Technical field

The present disclosure relates to the field of electronic technologies, and in particular, to an antenna structure, a mobile terminal, and an antenna control method.

Background technique

At present, as the working frequency band of mobile terminals increases, the antenna environment becomes worse and worse, and the challenges faced by the antennas increase. One of the problems is that the antenna space is insufficient, and the number of antennas is increased. For example, 5G communication technology requires more than four main antennas, and there is a problem of isolation between the antenna and the antenna. The related art usually combines antennas of multiple frequency bands in one common antenna, such as GPS, WIFI and main antenna, and is realized by a multiplexer.

However, the frequency close to the external signal received by the shared antenna will cause a large insertion loss to the multiplexer, such as a GPS damper insertion loss of about 2 dB, and a WIFI decimator insertion loss of about 2.3 dB. This leads to a drop in antenna performance.

Summary of the invention

An object of the present disclosure is to provide an antenna structure, a mobile terminal, and an antenna control method, which are used to solve the problem that a signal having a similar frequency in an external signal received by a mobile terminal in the related art causes a large insertion loss to a multiplexer.

a multiplexer having a signal input end and a plurality of signal output ends, wherein the plurality of signal output ends respectively correspond to a radio frequency module connected to a preset frequency band;

a bypass switch connected between the signal input terminal and each of the signal output terminals;

Wherein, one end of the bypass switch is connected to the signal input end, and the other end is connected between the corresponding signal output end and the radio frequency module.

In another aspect, an embodiment of the present disclosure further provides a mobile terminal, including the antenna structure as described in the foregoing embodiments.

In a further aspect, the embodiment of the present disclosure further provides an antenna control method, which is applied to the mobile terminal as described above, and includes:

Obtaining the number of antennas that the mobile terminal is currently in working state;

When the number of the antennas in the working state is one, generating a first control instruction for controlling the bypass switch closure of the corresponding antenna;

According to the first control instruction, the bypass switch corresponding to the antenna in the working state is controlled to be closed.

Thus, in the above solution of the embodiment of the present disclosure, by connecting a bypass switch between the signal input end of the multiplexer and each of the signal output ends, when the mobile terminal is in an active state, only one antenna is associated with the antenna. The bypass switch is closed, which can reduce the insertion loss of the signal with similar frequency in the external signal to the multiplexer, improve the performance of the antenna, and improve the user experience.

First embodiment

1 and 2 are schematic diagrams showing the circuit configuration of an antenna structure according to a first embodiment of the present disclosure. The hardware architecture of the antenna structure will be specifically described below.

The embodiment provides an antenna structure, including: a multiplexer having a signal input end and a plurality of signal output ends, wherein the plurality of signal output ends respectively correspond to a radio frequency module connected to a preset frequency band; and are connected to the signal input end and each A bypass switch between the signal outputs.

It should be noted that the preset frequency band refers to the working frequency band of the mobile terminal antenna, that is, different RF modules have different working frequency bands.

Here, as shown in FIG. 1, an alternative embodiment of the antenna structure of the present disclosure.

The multiplexer includes: a signal input end, a first signal output end, a second signal output end, and a third signal output end.

The first signal output end is electrically connected to the radio frequency module of the first preset frequency band.

Here, specifically, the radio frequency module of the first preset frequency band may be a communication radio frequency module, which can be understood as a communication antenna, as shown in FIG. 1 .

Here, the communication antennas on the mobile terminal are generally four, and one of the communication antennas is connected to the signal output end of the multiplexer.

It should be noted that the working frequency band of the communication radio frequency module may be multiple frequency bands. For example, the GSM communication system usually uses the frequency band, GSM850 (global mobile communication system), its working frequency band is 824MHz ~ 894MHz, GSM900 (global mobile communication system) its working frequency band is 890MHz ~ 960MHz, DCS1800 (digital communication system), its working frequency band For: 1710MHz ~ 1880MHz, PCS1900 (personal communication service system), its working frequency range is: 1880MHz ~ 1990MHz.

The second signal output end is electrically connected to the radio frequency module of the second preset frequency band.

Here, specifically, the radio frequency module of the second preset frequency band may be a WIFI radio frequency module, which can be understood as a WIFI antenna, as shown in FIG. 1 .

It should be noted that the working frequency bands of the WIFI radio frequency module are: 2.4 GHz and 5 GHz.

Here, there are generally two WIFI antennas on the mobile terminal, and the working frequency bands are 2.4 GHz and 5 GHz, respectively. One of the WIFI antennas is connected to the signal output of the multiplexer.

The third signal output end is electrically connected to the radio frequency module of the third preset frequency band.

Here, specifically, the radio frequency module of the third preset frequency band may be a GPS radio frequency module, which can be understood as a GPS antenna, as shown in FIG. 1 .

It should be noted that the working frequency band of the GPS radio frequency module is: 1575.42±1.023MHz.

As shown in FIG. 1, the bypass switch includes: a first bypass switch 2, one end of the first bypass switch 2 is directly connected to the signal input end, and the other end is connected to the first signal output end and the first preset frequency band. Between RF modules (communication RF modules);

a second bypass switch 3, one end of the second bypass switch 3 is directly connected to the signal input end, and the other end is connected between the second signal output end and the radio frequency module (WIFI radio frequency module) of the second preset frequency band;

The third bypass switch 4 has one end directly connected to the signal input end and the other end connected between the third signal output end and the radio frequency module (GPS radio frequency module) of the third preset frequency band.

Further, the antenna structure of this embodiment further includes: a shared antenna 1 connected to the signal input end.

Here, the signal input end of the multiplexer can be connected to the shared antenna 1 in two ways.

First, the signal input terminal is directly connected to the shared antenna 1, as shown in FIG.

Second, as shown in FIG. 2, another alternative embodiment of the antenna structure of the present disclosure. The signal input end can also be connected with the shared antenna 1 with a switch 5, one end of the switch 5 connected to the shared antenna 1, and the first bypass switch 2, the second bypass switch 3 and the third bypass switch 4. One end of any one of the bypass switches is connected.

As shown in FIG. 1, the signal input end of the multiplexer is directly connected to the shared antenna 1, based on the hardware configuration and connection relationship of the antenna structure, when the GPS antenna (GPS radio frequency module), the WIFI antenna (WIFI radio frequency module), and the communication antenna When only one antenna is in operation (the communication RF module), the mobile terminal can control the bypass switch corresponding to the antenna in the working state to be closed, and the other bypass switches are disconnected.

For example, if only the GPS antenna is currently working, the third bypass switch 4 is closed, and the remaining bypass switches are turned off, and the external receiving signal received by the shared antenna 1 is turned on to the GPS path through the third bypass switch 4. In this way, the external receiving signal is prevented from flowing into the WIFI antenna or the communication antenna, and the external receiving signal basically passes only through the third bypass switch 4, which is less than the loss through the multiplexer, and the performance of the antenna is improved.

It should be noted that after the external signal is turned on to the GPS path through the third bypass switch 4, the internal filter processing is performed, and only the antenna signal of the working frequency band corresponding to the GPS antenna passes, and the antenna signals of the remaining working frequency bands are filtered out. .

Here, the radio frequency module on other mobile terminals also has a filtering processing function, which will not be described here.

When more than one of the GPS antenna (GPS radio frequency module), the WIFI antenna (WIFI radio frequency module), and the communication antenna (communication radio frequency module) work, the mobile terminal can control the bypass switch corresponding to the antenna in the working state to be off. The bypass switch corresponding to the antenna that is on and not in operation is also disconnected.

Further, the mobile terminal is provided with a plurality of communication antennas (generally four) and a plurality of WIFI antennas (generally two). Wherein one of the plurality of communication antennas is connected to a signal output end of the multiplexer and one of the plurality of WIFI antennas is connected to a signal input end of the multiplexer.

Here, if one of the GPS antenna and the WIFI antenna in the antenna structure works simultaneously with the communication antenna, the mobile terminal may choose to temporarily turn off the communication antenna (the communication antenna is a shared communication antenna), and control the third bypass switch 4 or the The two bypass switches 3 are closed. In this way, the shared antenna 1 works only for the GPS antenna or the WIFI antenna, so that the performance of the GPS antenna or the WIFI antenna is improved, and user satisfaction is improved.

It can be further explained that when the GPS antenna, the WIFI antenna and the communication antenna work at the same time, and the signal of the WIFI antenna is good, the mobile terminal can choose to temporarily turn off the WIFI antenna (the WIFI antenna is a shared WIFI antenna) and the communication antenna ( The communication antenna is a shared communication antenna), and the third bypass switch 4 is controlled to be closed. In this way, the shared antenna 1 is only operated by the GPS antenna, so that the performance of the GPS antenna is improved and the user satisfaction is improved.

Similarly, when the GPS antenna or the WIFI antenna (the WIFI antenna is a shared WIFI antenna) is in a standby state, and the communication antenna is downloading data from the mobile network, the mobile terminal may select to temporarily turn off the GPS and WIFI functions of the shared antenna 1. , the first bypass switch 2 is controlled to be closed. In this way, the shared antenna works only for the communication antenna, which improves the performance of the communication antenna and ultimately improves user satisfaction.

As shown in FIG. 2, a signal switch can be connected to the shared antenna 1 with a switch 5, an end of the switch 5 connected to the shared antenna 1, and a first bypass switch 2, a second bypass switch 3, and a third One end of any one of the bypass switches 4 is connected. Based on the hardware configuration and connection relationship of the antenna structure, when only one antenna of the GPS antenna (GPS radio frequency module), WIFI antenna (WIFI radio frequency module) and communication antenna (communication radio frequency module) works, the mobile terminal can be controlled to work. The bypass switch corresponding to the state antenna is closed and the switch 5 is open, and the other bypass switches are open.

When more than one of the GPS antenna (GPS radio frequency module), the WIFI antenna (WIFI radio frequency module), and the communication antenna (communication radio frequency module) work, the mobile terminal can control the bypass switch corresponding to the antenna in the working state to be off. The bypass switch corresponding to the antenna that is on and not in operation is also turned off, while the control switch 5 is closed.

It should be noted that, as shown in the antenna structure shown in FIG. 2, since the switch 5 is connected between the signal input end and the shared antenna 1, the influence of the multiplexer on the switching path can be further reduced, and the antenna performance can be further improved.

Embodiments of the present disclosure also provide a medium mobile terminal including the antenna structure as described above.

According to the antenna structure provided by the embodiment of the present disclosure, by connecting a bypass switch between the signal input end of the multiplexer and each signal output end, based on the antenna structure, when there is only one antenna in the working state of the mobile terminal, The bypass switch corresponding to the antenna is closed, which can reduce the insertion loss of the signal with similar frequency in the external signal to the multiplexer, improve the performance of the antenna, and improve the user experience.

Second embodiment

As shown in FIG. 3, a flowchart of an antenna control method according to a second embodiment of the present disclosure is applied to a mobile terminal including the antenna structure as described in the first embodiment. The implementation process of the method will be specifically described below with reference to the flowchart.

Step 101: Obtain the number of antennas that the mobile terminal is currently in working state.

Here, when the number of antennas in the working state is one, step 102 is performed; when the number of antennas in the working state is greater than one, step 104 is performed.

It should be noted that there are multiple antennas disposed on the mobile terminal. Generally include: GPS antenna, WIFI antenna and communication antenna. Of course, with the development of communication technology, more antennas with other functions can be set.

Step 102: When the number of the antennas in the working state is one, generating a first control instruction for controlling the bypass switch closure of the corresponding antenna.

For example, when the mobile terminal acquires that only the GPS antenna is currently working, a first control command for controlling the closing of the GPS antenna corresponding bypass switch is generated.

It should be noted that the remaining bypass switches that do not receive the first control command may be disconnected, or the mobile terminal may also generate control for controlling the bypass switch disconnection except the GPS antenna corresponding bypass switch. The switch is turned off, so that the bypass switches corresponding to the other antennas are disconnected except for the bypass switch corresponding to the antenna in the working state.

Step 103: Control, according to the first control instruction, that the bypass switch corresponding to the antenna in the working state is closed.

Step 104: When the number of antennas in the working state is greater than one, generate a second control command for controlling the bypass switch of the antenna to be turned off.

Step 105: According to the second control instruction, the bypass switch corresponding to the antenna that controls the working state and the bypass switch corresponding to the antenna that is not in the working state are all turned off.

It should be noted that steps 101 to 105 of the above method can be applied to the antenna structure of the mobile terminal as shown in FIG. 1.

The antenna control method provided by the embodiment of the present disclosure is based on an antenna structure connecting a bypass switch between a signal input end of the multiplexer and each signal output end, and the antenna can be used when there is only one antenna in the working state of the mobile terminal. The corresponding bypass switch is closed, which can reduce the insertion loss of the signal with similar frequency in the external signal to the multiplexer, improve the performance of the antenna, and improve the user experience.

Third embodiment

As shown in FIG. 4, a flowchart of an antenna control method according to a third embodiment of the present disclosure is applied to a mobile terminal including the antenna structure as described in the first embodiment. The implementation process of the method will be specifically described below with reference to the flowchart.

First, it should be noted that the embodiments of the present disclosure are applicable to the antenna structure as shown in FIG. 2. That is, a switch 5 is connected between the signal input end of the multiplexer of the mobile terminal and the shared antenna 1, and one end of the switch 5 connected to the shared antenna 1 and the first bypass switch 2, the second bypass switch 3, and the Any one of the three bypass switches 4 is connected.

The specific steps of the antenna control method of the embodiment of the present disclosure are as follows:

Step 201: Obtain the number of antennas that the mobile terminal is currently in working state.

Here, when the number of antennas in the active state is one, step 202 and step 204 are respectively performed. That is, step 202 is performed in parallel with step 204; when the number of antennas in the active state is greater than one, step 206 and step 208 are respectively performed, wherein step 206 and step 208 are performed in parallel.

Step 202: When the number of the antennas in the working state is one, generate a first control instruction for controlling the bypass switch closure of the corresponding antenna.

Step 203: Control, according to the first control instruction, that the bypass switch corresponding to the antenna in the working state is closed;

Step 204: When the number of antennas in the working state is one, generating a third control instruction for controlling the disconnection of the switch.

Step 205, controlling the switch to be turned off according to the third control instruction.

It should be noted that when there is only one antenna in the working state, the mobile terminal closes the bypass switch corresponding to the antenna in the working state, and also disconnects the switch 5, so that the external antenna 1 is received. The receiving signal is turned on to the antenna path in the working state through the bypass switch, and the external receiving signal only passes through the working path, so that the multiplexer can be further reduced while preventing the external receiving signal from flowing into other antennas. The effect on the switching path further improves the antenna performance.

Step 206: When the number of antennas in the working state is greater than one, generate a second control instruction for controlling the bypass switch of the antenna to be turned off.

Step 207: Control, according to the second control instruction, that the bypass switch corresponding to the antenna in the working state and the bypass switch corresponding to the antenna not in the working state are all disconnected.

Step 208, when the number of antennas in the working state is greater than one, generating a fourth control instruction for controlling the closing of the switch.

Step 209, controlling the switch to be closed according to the fourth control instruction.

It should be noted that when more than one antenna of the GPS antenna (GPS radio frequency module), the WIFI antenna (WIFI radio frequency module), and the communication antenna (communication radio frequency module) work, the mobile terminal can control the antenna corresponding to the working state. The bypass switches are all open, and the bypass switch corresponding to the antenna that is not in operation is also turned off, while the control switch 5 is closed.

The antenna control method provided by the embodiment of the present disclosure is based on connecting a bypass switch between a signal input end of the multiplexer and each signal output end, and connecting a switch antenna between the signal input end of the multiplexer and the shared antenna. The structure, when there is only one antenna in the working state of the mobile terminal, the bypass switch corresponding to the antenna can be closed, and the switch between the connection signal input end and the shared antenna can be disconnected, thereby reducing the frequency of the external signal. The insertion loss caused by the signal to the multiplexer can further reduce the influence of the multiplexer on the switching path, thereby further improving the antenna performance and improving the user experience.
