The smart pen 100 and the electronic device according to an embodiment of the present application are described below with reference to fig. 2 to 13.

As shown in fig. 2 and 3, according to the smart pen 100 of some embodiments of the present application, the smart pen 100 includes: a pen body 102 and a first antenna module 104. The first antenna module 104 is disposed on the pen body 102, so that a disadvantage that the first antenna module 104 is disposed on the device body 202 of the electronic device is avoided, especially, an influence of the first antenna module 104 on an original antenna layout of the device body 202 is avoided, and an influence of the first antenna module 104 on a screen occupation ratio of a display screen in the device body 202 is also avoided.

Further, as shown in fig. 2, the first antenna module 104 includes a radio frequency module 106, a horn antenna 108, and a waveguide 110. The rf module 106 and the feedhorn 108 are communicated with each other through the waveguide 110, and the rf module 106 and the feedhorn 108 are used in cooperation, so that the first antenna module 104 has the capability of transmitting and receiving signals, and the first antenna module 104 can be used independently of the device body 202. That is, in the process of using the smart pen 100 in cooperation with an electronic device, the first antenna module 104 can be directly controlled to transmit and receive signals, and it is ensured that the first antenna module 104 does not affect the use of the antenna module on the device body 202 of the electronic device used in cooperation with the smart pen 100.

Therefore, in this embodiment, the first antenna module 104 is directly disposed on the pen body 102 of the smart pen 100, so that structural interference between the original antenna modules on the first antenna module 104 and the device body 202 of the electronic device can be avoided, and the device body 202 does not need to be greatly improved, and meanwhile, the screen occupation ratio of the display screen on the device body 202 is ensured, and the relative independence of the antenna module 104 is ensured.

Particularly, as shown in fig. 1, the antenna module 104 ' in the related art has a small gain, and if the gain is to be increased, a plurality of antenna modules 104 ' are required to be used together, and a feed network with one or more feed ports is required to be used together with a plurality of antenna modules 104 ', which brings loss of the feed network itself. The structure improvement of the horn antenna 108 in this embodiment effectively improves the gain of the first antenna module 104 itself, and then avoids using a plurality of first antenna module 104 arrays, and further avoids using one-to-many feed networks, and also avoids the loss of the feed networks themselves.

As shown in fig. 2, in the embodiment of the present invention, one end of the feedhorn 108 is communicated with the rf module 106 through the waveguide 110, and the other end of the feedhorn 108 is provided with an opening, and the opening of the feedhorn 108 is gradually increased in a direction away from the rf module 106. That is, the horn antenna 108 is a horn-shaped structure, and the end of the horn antenna 108 with the smaller opening is disposed toward the rf module 106, and the end of the horn antenna 108 with the larger opening is disposed toward the outside of the pen body 102. This can greatly improve the gain of the first antenna module 104, so that when the signal transmitted by the rf module 106 propagates in the feedhorn 108, the signal increases with the increase of the aperture of the feedhorn 108, and the gain on the rf path is also improved.

As a possible implementation, the first antenna module 104 is a millimeter wave antenna module, and the number of the first antenna modules 104 is one. That is, the millimeter wave antenna module can be directly disposed on the pen body 102 in this embodiment, and only one millimeter wave antenna module needs to be disposed.

Specifically, the size of the millimeter wave antenna module is generally 6mm × 6mm, and considering the size of the millimeter wave antenna module, if the millimeter wave antenna module is disposed on the device body 202 of the electronic device, on one hand, the millimeter wave antenna module will affect other original antenna modules of the device body 202, and on the other hand, the screen occupation ratio of the display screen will be sacrificed (because the millimeter wave antenna cannot penetrate through the metal of the display layer of the screen, only in the black border area of the display screen, that is, the non-display area). Therefore, the present embodiment skillfully installs the millimeter wave antenna module on the pen body 102, thereby avoiding various disadvantages of installing the millimeter wave antenna module on the device body 202.

In addition, because the first antenna module 104 includes the horn antenna 108 with gradually changing aperture, the horn antenna 108 can improve the overall gain effect of the first antenna module 104, only one first antenna module 104 needs to be used, a plurality of first antenna module 104 arrays do not need to be used, and then one-to-many feed network is avoided, and the loss of the feed network itself is also avoided.

As shown in fig. 4 and 5, according to the electronic device of some embodiments of the present application, the electronic device includes a device body 202, a smart pen 100, and a first antenna module 104. Wherein, the smart pen 100 uses with the cooperation of equipment body 202 to the smart pen 100 is detachable with the equipment body 202 and is connected, and the smart pen 100 can be installed on the equipment body 202, also can separate the use with the equipment body 202. The first antenna module 104 is disposed on the smart pen 100, so that a disadvantage that the first antenna module 104 is disposed on the device body 202 is avoided, especially, an influence of the first antenna module 104 on an original antenna layout of the device body 202 is avoided, and an influence of the first antenna module 104 on a screen occupation ratio of a display screen in the device body 202 is also avoided.

In addition, as shown in fig. 4 and 5, the first antenna module 104 includes a radio frequency module 106, a horn antenna 108, and a waveguide 110. The rf module 106 and the feedhorn 108 are communicated with each other through the waveguide 110, and the rf module 106 and the feedhorn 108 are used in cooperation, so that the first antenna module 104 has the capability of transmitting and receiving signals, and the first antenna module 104 can be used independently of the device body 202. That is, in the process of using the smart pen 100 in cooperation with an electronic device, the first antenna module 104 can be directly controlled to transmit and receive signals, and it is ensured that the first antenna module 104 does not affect the antenna module on the device body 202 of the electronic device used in cooperation with the smart pen 100.

As shown in fig. 4 and 5, in the present embodiment, the first antenna module 104 is directly disposed on the smart pen 100, so that structural interference between the first antenna module 104 and the original antenna module on the device body 202 can be avoided, and further, the device body 202 does not need to be improved greatly. And this application embodiment directly sets up first antenna module 104 on smart pen 100, has guaranteed that the screen of display screen accounts for than on equipment body 202. Meanwhile, the first antenna module 104 can be used independently of the device body 202, which ensures the relative independence of the first antenna module 104.

In addition, as shown in fig. 6, one end of the feedhorn 108 is communicated with the rf module 106 through the waveguide 110, and the other end of the feedhorn 108 is provided with an opening, and the opening of the feedhorn 108 is gradually increased in a direction away from the rf module 106. That is, the horn antenna 108 is a horn-shaped structure, and the end of the horn antenna 108 with the smaller opening is disposed toward the rf module 106, and the end of the horn antenna 108 with the larger opening is disposed toward the outside of the pen body 102. In this way, in the direction away from the rf module 106, the aperture of the opening of the horn antenna 108 is gradually increased, which greatly improves the gain of the first antenna module 104, so that when a signal transmitted by the rf module 106 propagates in the horn antenna 108, the signal increases with the increase of the aperture of the horn antenna 108, and also improves the gain on the rf path.

Particularly, as shown in fig. 1, the antenna module 104 ' in the related art has a small gain, and if the gain is to be increased, a plurality of antenna modules 104 ' are required to be used together, and a feed network with one or more feed ports is required to be used together with a plurality of antenna modules 104 ', which brings loss of the feed network itself. In this embodiment, through the structural improvement of the horn antenna 108, the gain of the first antenna module 104 itself is effectively improved, so that the use of a plurality of first antenna module 104 arrays is avoided, the use of one-to-many feed networks is further avoided, and the loss of the feed networks is also avoided.

As a possible implementation, the first antenna module 104 is a millimeter wave antenna module, and the number of the first antenna modules 104 is one. That is, the present embodiment can directly set the millimeter wave antenna module on the smart pen 100, and only one millimeter wave antenna module needs to be set.

Specifically, the size of the millimeter wave antenna module is generally 6mm × 6mm, and considering the size of the millimeter wave antenna module, if the millimeter wave antenna module is disposed on the device body 202 of the electronic device, on one hand, the millimeter wave antenna module will affect other original antenna modules of the electronic device, and on the other hand, the screen occupation ratio of the display screen will be sacrificed (because the millimeter wave antenna cannot penetrate through the metal of the display layer of the screen, only in the black border area of the display screen, that is, the non-display area). Therefore, the present embodiment skillfully sets the millimeter wave antenna module on the smart pen 100, thereby avoiding various disadvantages of setting the millimeter wave antenna module on the device body 202.

As a possible implementation mode, the device body is provided with a mounting groove 204, and the smart pen can be accommodated in the mounting groove 204, so that the detachable connection between the smart pen 100 and the device body 202 is ensured. And, when the smart pen 100 is received in the mounting groove 204, the opening direction of the horn antenna 108 is the same as the opening direction of the mounting groove 204 to ensure the transmission and reception of signals.

As a possible embodiment, the device body 202 includes a side wall, and the opening of the mounting groove 204 is located on the side wall. In this way, after the smart pen 100 is mounted to the apparatus body 202 through the mounting groove 204, the opening of the horn antenna 108 is disposed toward the side of the apparatus body 202, so that the first antenna module 104 can transmit or receive signals toward the side of the apparatus body 202.

Particularly, when the first antenna module 104 is used for gesture recognition, since the first antenna module 104 can transmit and receive signals to and from the side of the device body 202, the side of the device body 202 can be used as a recognition area, and the user's actions on the side of the device body 202 can be captured by the first antenna module 104, so that the recognition range of the electronic device is enlarged, and the user can use the electronic device conveniently.

As a possible implementation manner, as shown in fig. 6, 7 and 8, an annular groove 206 is provided on the smart pen 100, a positioning structure is provided inside the mounting groove 204, and the positioning of the smart pen 100 in the mounting groove 204 is ensured by the cooperation of the positioning structure and the annular groove 206. Specifically, when the smart pen 100 is installed inside the mounting groove 204, the annular groove 206 is opposite to the position of the positioning structure, and at this time, the positioning structure can stretch into the inside of the annular groove 206, so that the positioning of the smart pen 100 is realized by abutting against the inside of the annular groove 206, and the smart pen 100 is prevented from falling off.

As a possible embodiment, as shown in fig. 8, the positioning structure includes an elastic member 208 and a positioning portion 210 used in cooperation. One end of the elastic element 208 is connected with the inner wall of the mounting groove 204, the other end of the elastic element 208 is provided with a positioning part 210, and the structure of the positioning part 210 is matched with the inner wall of the annular groove 206.

In the in-process at installation smart pen 100, stretch into the mounting groove 204 with smart pen 100 inside, location portion 210 forces elastic component 208 to shrink under the butt effect of smart pen 100 outer wall, when ring channel 206 is located the position at location structure place, elastic component 208 orders about the inside that location portion 210 stretched into ring channel 206, and make the inner wall looks butt of location portion 210 and ring channel 206, and then realized that smart pen 100 is spacing at ring channel 206 opening direction, guaranteed that smart pen 100 stable installation is in mounting groove 204, can not drop because of the accident.

In one embodiment, the elastic member 208 may be a spring, and the positioning portion 210 may be an iron ball.

As a possible embodiment, as shown in fig. 8, in the axial direction of the mounting groove 204, the inner wall of the mounting groove 204 includes a first wall section 212 and a second wall section 214 connected, the second wall section 214 is connected to the notch of the mounting groove 204 and the first wall section 212, and the caliber of the mounting groove 204 at the second wall section 214 is gradually increased. That is, the structure of the mounting groove 204 is further optimized in this embodiment, so that the inner wall of the mounting groove 204 is divided into two parts, and the inside of the mounting groove 204 near the opening can be used in cooperation with the horn antenna 108, thereby improving the gain of the first antenna module 104.

Specifically, after the smart pen 100 is installed inside the installation slot 204, the smart pen 100 is located at the position of the first wall section 212, and the second wall section 214 is located between the smart pen 100 and the slot of the installation slot 204, and is connected to the horn antenna 108 and the slot of the smart pen 100. So designed, after the smart pen 100 is installed inside the mounting groove 204, the second wall section 214 can further diffuse the signal, so that the second wall section 214 cooperates with the horn antenna 108, and the gain of the first antenna module 104 is further improved.

As a possible implementation manner, as shown in fig. 8, in the axial cross section of the mounting groove 204, the slope of the second wall section 214 relative to the axis of the mounting groove 204 is equal to the slope of the horn 108 relative to the axis of the mounting groove 204. That is, when the smart pen 100 is installed inside the installation slot 204, there is a smooth transition between the horn antenna 108 and the second wall section 214, and in the axial cross section of the installation slot 204, the second wall section 214 is located on the same line as the inner wall of the horn antenna 108. So design for square smart pen 100 installs the inside back of mounting groove 204, and horn antenna 108 and second wall section 214 directly link up, and the ladder can not appear in the position that both link up, and guaranteed that horn antenna 108 and second wall section 214 are the same for the degree of inclination of mounting groove 204 axis, and then guaranteed that horn antenna 108 is the same to the diffusion effect of signal with second wall section 214, and then make second wall section 214 and horn antenna 108 cooperation, further promote the gain nature of first antenna module 104.

As a possible implementation, as shown in fig. 5 and 8, the electronic device further includes a second antenna module 216, a detection component, and a control module. The second antenna module 216 and the detection component are arranged on the equipment body 202, and the control module is electrically connected with the first antenna module 104 and the second antenna module 216; the detection part can detect the relative position of the smart pen 100 and the equipment body 202, detect whether the smart pen 100 is installed on the equipment body 202, and send the detection result to the control module, and the control module controls at least one of the first antenna module 104 and the second antenna module 216 to work according to the detection result of the detection part.

In a specific embodiment, the detection component may be a sensor.

Specifically, as shown in fig. 9, if the detection component detects that the smart pen 100 is installed on the device body 202, the control module controls the first antenna module 104 and the second antenna module 216 to have both transmitting and receiving functions, and at this time, the first antenna module 104 and the second antenna module 216 can be used independently. Since the first antenna module 104 faces the side of the apparatus body 202 at this time, the first antenna module 104 and the second antenna module 216 are used cooperatively, the first antenna module 104 can detect the area on the side of the apparatus body 202, and the second antenna module 216 can detect the area on the other direction. Compared with the scheme of fig. 1 in which the antenna module 104 'is disposed on the display screen of the device body 202', the present embodiment obviously expands the detection area of the electronic device and increases the identification range of the electronic device. The dotted line in fig. 9 indicates the detection area.

Specifically, if the detection component detects that the smart pen 100 is not installed on the device body 202, the control module controls the first antenna module 104 to have only a transmitting function, and controls the second antenna module 216 to have only a receiving function, at this time, the first antenna module 104 and the second antenna module 216 are used in cooperation, the second antenna module 216 on the device body 202 serves as a receiving antenna, and receives a signal transmitted by the first antenna module 104 on the smart pen 100, and in this state, because the gain of the horn antenna 108 is high, the device body 202 can be controlled at a longer distance, and the sensitivity of the device body 202 identification is improved.

As a possible implementation manner, the use of the horn antenna 108 effectively increases the gain of the first antenna module 104 itself, and further avoids using a plurality of first antenna module 104 arrays, so that it is not necessary to set a plurality of first antenna module 104 arrays for use, and only one first antenna module 104 may be provided. In addition, the device body 202 is provided with three display screens, and the number of the second antenna modules 216 is three and is distributed on the periphery of the display screens. Moreover, after the smart pen 100 is installed on the device body 202, the first antenna module 104 and the third second antenna module 216 are distributed along the periphery of the display screen, so that the display screen can work around, and the detection area and the detection range of the electronic device are effectively improved.

As a possible implementation, the first antenna module 104 is a millimeter wave antenna module. That is, the millimeter wave antenna module can be directly disposed on the pen body 102 in this embodiment, and only one millimeter wave antenna module needs to be disposed.

Specifically, the size of the millimeter wave antenna module is generally 6mm × 6mm, and considering the size of the millimeter wave antenna module, if the millimeter wave antenna module is disposed on the device body 202 of the electronic device, on one hand, the millimeter wave antenna module will affect other original antenna modules of the electronic device, and on the other hand, the screen occupation ratio of the display screen will be sacrificed (because the millimeter wave antenna cannot penetrate through the metal of the display layer of the screen, the millimeter wave antenna module can only be in the black border area, that is, the non-display area of the display screen). Therefore, the present embodiment skillfully arranges the millimeter wave antenna module on the pen body 102, thereby avoiding various disadvantages of arranging the millimeter wave antenna module on the device body 202.

As a possible implementation, the second antenna module 216 is a patch antenna module. That is, this embodiment is provided with the patch antenna module on equipment body 202 for millimeter wave antenna module on three patch antenna module cooperation smart pen 100 uses, can realize that the display screen of equipment body 202 and the directional diagram of the side of equipment body 202 cover. The side where the smart pen 100 is located has better detection sensitivity than the other sides.

As one possible implementation, the electronic devices include, but are not limited to, several: handheld terminal, panel computer, notebook computer.

Fig. 10 shows that an embodiment of the present application provides a control method of an electronic apparatus, which can be used for the electronic apparatus of the above embodiment, and as shown in fig. 10, the control method of the electronic apparatus:

step 302, acquiring the relative position of the intelligent pen and the equipment body;

and step 304, controlling the first antenna module on the smart pen and the second antenna module on the equipment body to work according to the relative position of the smart pen and the equipment body.

In the use process of the electronic equipment, the relative position between the intelligent pen and the equipment body is firstly obtained, and whether the intelligent pen and the equipment body are in a fit state or a separation device is judged. When the intelligent pen is installed on the equipment body, judging that the intelligent pen is attached to the equipment body; when the installation of intelligent pen was dismantled from the equipment body, judge the phase separation between intelligent pen and the equipment body. Then, according to the relative position between intelligent pen and the equipment body, the work of control first antenna module and second antenna module to adjust the mode of first antenna module and second antenna module.

Particularly, the first antenna module is arranged on the smart pen, and the first antenna module has stronger gain due to the horn antenna with the gradually-increased opening; the second antenna module is arranged on the equipment body and can be matched with the first antenna module for use. When the smart pen is installed on the equipment body through the installation part, the horn antenna of the first antenna module faces the side opening of the equipment body; the second antenna module is arranged above the equipment body, so that the first antenna module and the second antenna module can detect different positions of the equipment body.

In this embodiment, specifically, based on the condition that the smart pen was installed in the equipment body, control first antenna module and open transmission function and receive function, control second antenna module and open transmission function and receive function.

That is, if detect the smart pen and install on the equipment body, control first antenna module and second antenna module and all have transmission and receive function, first antenna module and the equal independent utility of second antenna module this moment. Because the first antenna module faces the side of the equipment body at this time, the first antenna module and the second antenna module are matched for use, the first antenna module can detect the area at the side of the equipment body, and the second antenna module can detect the area at the other direction. Compared with the scheme that the first antenna module is arranged on the display screen of the equipment body, the detection area of the electronic equipment is obviously enlarged, and the identification range of the electronic equipment is enlarged.

Fig. 12 is a schematic diagram showing a possible structure of a control device 500 of an electronic apparatus according to an embodiment of the present application. As shown in fig. 12, the control device 500 of the electronic apparatus includes:

a detection unit 502, configured to obtain a relative position between the smart pen 100 and the device body 202;

the control unit 504 is configured to control the first antenna module 104 on the smart pen 100 and the second antenna module 216 on the device body 202 to operate according to the relative positions of the smart pen 100 and the device body 202.

According to the embodiment of the present application, first, the detection unit 502 obtains the relative position between the smart pen 100 and the apparatus body 202, and the control unit 504 determines whether the smart pen 100 and the apparatus body 202 are in the attached state or the detached state. When the smart pen 100 is mounted on the device body 202, the control unit 504 determines that the smart pen 100 is attached to the device body 202; when the smart pen 100 is attached to and detached from the apparatus body 202, the control unit 504 determines that the smart pen 100 is separated from the apparatus body 202. Then, the control unit 504 controls the operation of the first antenna module 104 and the second antenna module 216 according to the relative position between the smart pen 100 and the device body 202, and adjusts the operation mode of the first antenna module 104 and the second antenna module 216. Specifically, the detection unit 502 may employ a sensor.

Specifically, if the detection unit 502 detects that the smart pen 100 is mounted on the device body 202, the control unit 504 controls the first antenna module 104 to have only transmitting and receiving functions, and controls the second antenna module 216 to have only transmitting and receiving functions. In this case, the first antenna module 104 and the second antenna module 216 can be used independently. Since the first antenna module 104 faces the side of the apparatus body 202 at this time, the first antenna module 104 and the second antenna module 216 are used cooperatively, the first antenna module 104 can detect the area on the side of the apparatus body 202, and the second antenna module 216 can detect the area on the other direction. By the design, the detection area of the electronic equipment is obviously enlarged, and the identification range of the electronic equipment is enlarged.

Specifically, if the detection unit 502 detects that the smart pen 100 is not installed on the device body 202, the control unit 504 controls the first antenna module 104 to have only a transmitting function, and controls the second antenna module 216 to have only a receiving function, at this time, the first antenna module 104 and the second antenna module 216 are used in cooperation, the second antenna module 216 on the device body 202 serves as a receiving antenna, and receives a signal transmitted by the first antenna module 104 on the smart pen 100, and in this state, because the gain of the horn antenna 108 is high, the device body 202 can be controlled at a longer distance, and the sensitivity of the device body 202 identification is improved.

The control device 500 of the electronic device in the embodiment of the present application may be a device, or may be a component, an integrated circuit, or a chip in the electronic device.

In a specific embodiment, the embodiment of the present application provides a new scheme for implementing a millimeter wave antenna module. Appearance: the millimeter wave antenna module is arranged at the top of the intelligent pen 100 of the electronic equipment, so that the influence on the appearance of the equipment body 202 of the electronic equipment is reduced, the space of the intelligent pen 100 is fully utilized, and the millimeter wave antenna does not need to be avoided by sacrificing too much appearance; the layout that the millimeter wave antenna is designed on the top of the smart pen 100 has the advantages that the influence on the original antenna module of the device body 202 is reduced to the minimum, and the performance of other antenna modules is guaranteed; the gain of a common millimeter wave antenna module is small, if the gain is to be improved, a plurality of antenna modules are required to be grouped together, and the loss of the feed network is brought in due to the fact that the grouped arrays of the plurality of antenna modules need one-to-many feed networks, in this embodiment, because the horn antenna 108 has the characteristic of high gain (the feed network is increased along with the increase of the aperture of the horn antenna 108), the horn antenna 108 is arranged on the smart pen 100 to achieve high gain, meanwhile, the loss of the feed network caused by the grouped arrays is reduced, and then, the gain on a radio frequency path is also improved; the millimeter wave antenna module is designed at the top of the intelligent pen 100, and other materials which attenuate signals greatly do not exist around the intelligent pen 100, so that the attenuation of the materials to the signals is reduced; when the smart pen 100 and the equipment body 202 are in the laminating state, because the smart pen 100 is generally designed at the bottom or the top or the side of the equipment body 202, under the laminating state, compared with the scheme of only the gesture recognition antenna module under the screen, the gesture recognition range can be increased.

Specifically, the smart pen 100 may be a square shape with a size of 5.7 × 4.5mm, or a cylindrical shape with a size of 8.9 mm. Under the intelligent pen 100 with the size, the gain horn of the horn antenna 108(12dBi) provided by the embodiment of the application is 6dB higher than the gain (6dBi) of the millimeter wave antenna module; the larger the size (aperture) of the horn antenna 108, the higher the gain.

In a specific embodiment, as shown in fig. 2 and fig. 3, a horn antenna 108 and a waveguide 110 are formed at the top of the smart pen 100, the horn antenna 108 is connected to the waveguide 110, and the waveguide 110 is connected to the radio frequency module 106; horn antenna 108 is used for transmission and reception; 3 patch antenna modules are arranged on the screen of the equipment body 202, and the 3 patch antennas are combined with the millimeter wave antenna module on the smart pen 100, so that the directional diagram coverage of the mobile phone screen and the side edge can be realized; wherein, the sensitivity of the side where the smart pen 100 is located is better than that of other sides.

A sensor is added at the joint of the intelligent pen 100 and the equipment body 202 and used for sensing the state of the intelligent pen 100; the smart pen 100 and the equipment body 202 have two states, which are respectively the attaching state and the separating state, and the attaching state is after the smart pen 100 is inserted into the equipment body 202, and the separating state is after the intelligent pen 100 is extracted from the equipment body 202, so that the working mode of the millimeter wave antenna module on the smart pen 100 and the patch antenna module on the equipment body 202 is determined.

When the smart pen 100 and the device body 202 are in a fit state, the sensor detects the state of the smart pen 100, and the device body 202 and the smart pen 100 have transmitting and receiving functions at the same time; compared with the scheme of only a millimeter wave gesture radar on the screen, the gesture recognition range is enlarged in the attaching state of the intelligent pen 100;

when the smart pen 100 separates with equipment body 202, the state that the sensor detected the smart pen 100, and the millimeter wave antenna module on the smart pen 100 only possesses the function of transmission, and the patch antenna module on the equipment body 202 only possesses the function of receiving, and both combine to use, and the patch antenna module under the screen is as receiving antenna, receives the signal that the smart pen 100 transmission was come. In this state, the horn antenna 108 has a high gain, so that the mobile phone can be controlled at a longer distance, and the recognition sensitivity of the device body 202 is improved.

Further, a ring of annular grooves 206 may be designed at a certain distance from the top of the smart pen 100, the opening of the mounting groove is designed to be in a "v" shape on the device body 202, the slope of the ring is the same as that of the horn antenna 108 on the smart pen 100, and an iron ball and a spring are added at a certain distance from the opening of the mounting groove.

The opening part of the mounting groove is provided with a splayed structure with a certain length, and meanwhile, the design of a spring and an iron ball is added at a certain distance of the opening of the mounting groove, so that the splayed structure is matched with the annular groove 206 of the intelligent pen 100, and the functions of positioning the intelligent pen 100 and electrically connecting the intelligent pen with the mounting groove are achieved. According to the design, when the intelligent pen 100 is in a laminating state, after the horn antenna 108 on the intelligent pen 100 is combined with the splayed structure on the mounting groove, the caliber of the horn antenna 108 is enlarged, and therefore radiation of the horn antenna 108 is increased.
