In recent years, with the development of information communication technologies such as mobile internet and internet of things, data traffic is continuously and explosively increasing. The number of 5G base stations is rapidly increasing, and the problem of shortage of site resources is increasingly appearing.
In order to rapidly deploy 5G communication equipment, a 5G site is mainly implemented by adding a 5G antenna and equipment to the original 4G site resources, so that a multi-frequency base station antenna becomes the mainstream. The 4G and 5G integrated active and passive integrated base station antenna has more advantages in space size, wind load and management, is widely accepted and applied in the 5G base station deployment process, and is an important direction for the future base station antenna evolution.
Fig. 1 shows a schematic connection diagram of an integrated active and passive base station antenna 100, with a conventional passive antenna on the top and an active antenna on the bottom, both antennas being stacked together. The most critical technology in the integrated deployment of the base station antenna with integrated active antenna and passive antenna is the application of the frequency selective surface 110, and the patent CN 112599974a discloses a frequency selective surface. The frequency selective surface has wave-transparent characteristics for high frequency signals emitted from the antenna element 130 such as 5G, and forms an open circuit for the high frequency signals, while it forms a ground structure for low frequency signals emitted from the low frequency radiation unit 120 of the conventional antenna, and prohibits the penetration of the low frequency signals. Based on the application of the technology, the integrated fusion of the front and back stacking forms of the active antenna and the passive antenna can be completed.
Unlike the conventional antenna, the conventional plate-shaped antenna basically uses an aluminum alloy plate with certain strength and rigidity as a reflection surface and a mounting surface of the oscillator, and the frequency selection surface is made of resin, plastic and the like and has a small thickness as a whole, so that the conventional plate-shaped antenna generally does not have high rigidity, so that the whole is highly fragile, and particularly when the antenna vibrates, the frequency selection surface is easily broken. In addition, the frequency selection surface usually needs to be provided with a vibrator, but the vibrator is usually not easy to place due to the weak rigidity of the frequency selection surface.

As mentioned above, the technical problem of the prior art is that the conventional problems in the background art are solved by the present disclosure, namely, the problem that the frequency selective surface has insufficient rigidity during the application process, and when the antenna vibrates, the frequency selective surface is easily broken.
In view of this technical problem, the inventors of the present disclosure have innovated to provide the frequency selection device with a protection device in which, since the middle portion of the frequency selection surface can be connected to the middle portion of the bridge member, the structural strength of the frequency selection surface becomes large, thereby being able to serve the purpose of protecting the frequency selection surface so that the frequency selection surface does not easily fail even in a vibration state.
The specific structure of the protection device proposed by the present disclosure is described below with reference to fig. 2A to 6, but those skilled in the art will appreciate that the specific embodiments herein are merely illustrative and not restrictive, as long as the technical solution that falls within the scope of the claims is the claimed content of the present disclosure.
In particular, the present disclosure proposes a protection device for protecting a frequency selective surface. The protection device 200 disclosed according to the present disclosure will be described below with the aid of fig. 2A and 2B. Fig. 2A shows a schematic structural view of a protection device 200 for protecting a frequency selective surface according to an embodiment of the present disclosure, and fig. 2B shows an assembly view of the protection device 200 for protecting a frequency selective surface mounted with a frequency selective surface and a bracket of the embodiment shown in fig. 2A.
As can be seen in fig. 2A and 2B, a protective device 200 for protecting a frequency selective surface 270 according to one embodiment of the present disclosure includes a support portion 210 at least one end (e.g., a left end of fig. 2A) of the protective device 200, the support portion 210 being configured for being fixed to a bracket (e.g., the bracket 280 of fig. 2B) via a mechanical connection; in addition, the protection device 200 for protecting the frequency selective surface 270 according to one embodiment of the present disclosure further includes a bridge member extending between both end portions (e.g., end portions on both left and right sides) of the protection device 200, wherein a connection member 220 for connecting a middle portion of the frequency selective surface 270 is provided at a middle portion of the bridge member to connect the middle portion of the frequency selective surface (e.g., the frequency selective surface 270 of fig. 2B) to the middle portion of the bridge member. In the technical solution according to the present disclosure, since the middle portion of the frequency selection surface 270 can be connected to the middle portion of the bridge member, the structural strength and rigidity of the frequency selection surface 270 become large, thereby being able to serve the purpose of protecting the frequency selection surface 270.
Here, the middle portion of the frequency selective surface 270 is not necessarily located in the middle of the frequency selective surface 270, and accordingly, the middle portion of the bridge member is not necessarily located in the middle of the bridge member. It will be understood by those skilled in the art that the middle portion or middle portion is merely an area, and can even be said to be the rest of the area except for the end portions (e.g., the left and right end portions). In the solution according to the present disclosure, it is sufficient that the middle portion of the frequency selective surface 270 can be connected to the middle portion of the bridge member via the connecting action of the connecting member 220, thereby increasing the overall rigidity of the frequency selective surface 270.
Preferably, in order to enable the frequency selective surface 270 to be smoothly connected to the bridge member shown in fig. 2A, in the embodiment shown in fig. 2B according to the present disclosure, the connection member 220 is configured on a mounting portion 221 extending from the protection device toward the frequency selective surface 270. That is, the mounting portion 221 is, for example, a mounting leg portion, and the connecting member 220 is, for example, an end portion with a screw hole through which the frequency selective surface 270 can be connected with the bridge member, for example, by means of a screw or a rivet, thereby increasing the structural strength of the frequency selective surface 270. Of course, it will be appreciated by those skilled in the art that the frequency selective surface may also be bonded to the above-described connecting member 220, for example, by means of glue.
Furthermore, preferably, in an embodiment according to the present disclosure (e.g., the embodiment shown in fig. 2A and 2B), the supporting portion 210 is further configured to support an end surface, i.e., for example, having a flat area, and the supporting end surface crimps the frequency selection surface 270 to the bracket 280 via the mechanical connection. In this manner, the frequency selective surface 270 can be crimped onto the carrier 280, thereby firmly securing the frequency selective surface 270 to the carrier 280. More preferably, in one embodiment according to the present disclosure (such as the embodiment shown in fig. 2A and 2B), the protection device 200 has two supporting end surfaces 210 and 210' at both ends of the protected device 200, so as to firmly press the frequency selection surface 270 onto the bracket 280 at both ends, respectively. In this way, the frequency selective surface 270 can be pressed against the bracket 280 more firmly, so that the frequency selective surface 270 can be fixed to the bracket 280 more firmly, further enhancing the rigidity of the frequency selective surface 270, thereby improving the interference resistance of the frequency selective surface 270.
In addition, as further shown in fig. 2A and 2B, in the embodiment shown in fig. 2A and 2B according to the present disclosure, the protection device 200 further includes a vibrator supporting portion 230, the vibrator supporting portion 230 being configured between the supporting portion 210' and the connection member 220 and configured to support a vibrator on a side of the protection device 200 away from the frequency selection surface 270. Furthermore, in the example shown in fig. 2A and 2B, a vibrator support is also formed between the support 210 and the connecting member 220 and is also formed for supporting a vibrator on a side of the protective device 200 remote from the frequency selective surface 270, so that the protective device 200 according to the example shown in fig. 2A and 2B can simultaneously support, for example, two vibrators. In this way, the vibrator (not shown in fig. 2A and 2B, but described later in conjunction with fig. 3A and 3B) can be supported well, so that on the one hand the vibrator can be supported well, and on the other hand the adverse effect on the frequency selective surface 270 due to the weight of the vibrator can also be reduced, i.e. the vibrator can be supported by means of the vibrator support portion 230, rather than by the frequency selective surface 270 alone, so that the frequency selective surface 270 is freed from the task of supporting the vibrator, further improving the immunity of the frequency selective surface 270. In the embodiment shown in fig. 2A and 2B, the protection device 200 includes two vibrator support portions 230, and those skilled in the art will appreciate that other numbers of vibrator support portions are possible. The height of the vibrator support portion 230 does not necessarily correspond to the height of the vibrator, and may be slightly lower than the height of the vibrator, for example.
In case the height of the vibrator and the height of the vibrator supporting part are close, in one embodiment according to the present disclosure, the vibrator supporting part 230 can further include a snap 232 configured to mechanically connect the vibrator to be mounted to the frequency selection surface 270 to the protection device 200. In this way, the vibrator can be well fixed to the protection device 200 disclosed according to the present disclosure. Specifically, the vibrator such as the low frequency radiation unit can be fixed to the protection device 200 for the antenna by, for example, the snaps 232 at four corners of the vibrator supporting part 230, the snaps 232 being circumferentially distributed by 4, and the reliability of the connection can be secured. Of course, it should be understood by those skilled in the art that two or more snaps 232 are possible, for example. The buckles 232 distributed circumferentially can fix not only the vibrator with the square radiating surface, but also the vibrator in a Cross (Cross) form. In the embodiment shown in fig. 2B, the protection device 200 for an antenna is in the form of a "bridge-type" support structure, and two ends of the support structure respectively bridge over the metal brackets 280 on two sides, and the fixing method may be in the form of detachable connection such as screws, rivets, or hooks, or in other fixed connection manners. It should be understood by those skilled in the art that the snap fastener is only one form of the snap fastener for fixing the vibrator to the vibrator supporting portion 230, and other forms of fixing structures are also feasible, such as fixing holes on the vibrator, and corresponding supporting convex columns or supporting fixing disks on the vibrator supporting portion 230, respectively.
It is also preferable that, in an embodiment according to the present disclosure, the protection device 200 further includes a receiving cavity 240, and the receiving cavity 240 is configured to allow a feeding member for feeding the vibrator to pass therethrough. More preferably, in an embodiment according to the present disclosure, a feeding board protection seat 250 is disposed at an end of the receiving cavity 240 close to the frequency selection surface 270, and the feeding board protection seat 250 is configured to receive a feeding board of the vibrator and is mechanically connected to the frequency selection surface 270. Specifically, the protection device 200 for an antenna is provided with a receiving cavity 240 for mounting a feeding member for feeding an element such as a low-frequency radiating element, which may be a receiving cavity for covering the feeding member from top to bottom, or a groove-shaped receiving cavity for guiding and positioning only the feeding member. As mentioned above, the antenna protection device 200 is further provided with the feeding board protection seat 250, the feeding board of the low-frequency radiating element can be accommodated in the feeding board protection seat 250, the feeding board protection seat 250 and the frequency selection surface 270 can be connected through the rivets 251, for example, this structure not only protects the oscillator pad, but also strengthens the local connection rigidity of the frequency selection surface 270, and the antenna protection device 200 can be compatible with different forms and types of radiating elements by adjusting the characteristics of the radiating elements on which the antenna protection device 200 is installed.
In addition, in order to optimize the radio frequency performance, required parts such as an isolation pin, a parasitic element, and the like may also be installed. Preferably, in the embodiment shown in fig. 2A and 2B according to the present disclosure, a side of the bridge member away from the frequency selection surface 270 is provided with a fixing member 260, and the fixing member 260 is configured to fix a parasitic element or an isolation pin. In this case, parts required for optimizing radio frequency performance, such as an isolation pin, a parasitic element, and the like, may be placed between the two elements such as the low frequency radiating element. Optionally, the fixing member 260 includes a snap groove for snapping the part. Specifically, the fixing member includes a retaining arm including a base portion formed to protrude outward from the bridge member and a retaining portion located on a side of the base portion away from the bridge member, and wherein the part is located between the retaining portion and the bridge member when the retaining arm retains the part.
Here, fig. 2A and 2B specifically show the connection relationship between the protection device 200 according to the present disclosure and various components such as the vibrator, the frequency selection surface, and the bracket. The rivet fixes the protector 200 to the brackets 280 at both sides of the antenna through the rivet hole while crimping the protector 200 for an antenna to the frequency selective surface 270, thereby strengthening the constraint rigidity at both sides of the frequency selective surface 270, and at the same time, the protector 200 for an antenna is provided with the connection member 220 such as the mounting leg in the middle thereof, the connection member 220 is connected to the frequency selective surface 270 through the rivet, and the freedom of shaking in the middle of the frequency selective surface 270 can be effectively reduced. Thereby forming a "bridge-type" connection structure that effectively increases the stiffness of the frequency selective surface 270. At the same time, a fastening device for the radiating element of the high-frequency oscillator can also be placed below the oscillator, such as the low-frequency radiating element, which is connected, for example, to a fixed receiving chamber 240 for the feed of the low-frequency radiating element, in a similar manner to the fastening device for the low-frequency radiating element.
Fig. 3A shows an assembly schematic of a protection device 300 for protecting a frequency selective surface mounted with a vibrator according to yet another embodiment of the present disclosure. In the embodiment shown according to fig. 3A, the two vibrators 332 and 332' are connected to the protective device 300, for example by means of vibrator supports, and are supported by means of the protective device 300, so that the frequency selective surface 370 is freed from the task of supporting the vibrators, improving the interference resistance of the frequency selective surface 370. Furthermore, transducer 332 can be secured, for example, by a structure at its surface 333, such as an opening and snap. Furthermore, a parasitic element 362 required for optimizing the radio frequency performance is installed between the two oscillators 332 and 332', and the parasitic element 362 can be fixed by, for example, a snap connection. Also, to further illustrate the shape of the receiving cavity, FIG. 3B illustrates a partial enlarged view at the receiving cavity in FIG. 3A. As can be seen from fig. 3B, the receiving cavity can be formed, for example, by means of mutually intersecting receiving subcavities 341 and 342, each receiving subcavity 341 or 342 can receive a feeding element, respectively, which are mutually intersecting to form mutually intersecting feeding elements for feeding the elements, for example, intersecting PCB boards, and furthermore, a feeding board protection seat 350 can be provided on the upper portion of the frequency selection surface 370, which can be fixed, for example, by means of a fixing element 343 onto the frequency selection surface 370.
Fig. 4 shows a schematic structural diagram of a protection device 400 for protecting a frequency selective surface according to another embodiment of the present disclosure. Although substantially identical to the protection device 200 for protecting a frequency selective surface shown in fig. 2A and 2B in terms of mounting and connection, the protection device is easier to manufacture than the embodiment shown in fig. 2A and 2B. Specifically, as can be seen in fig. 4, a protection device 400 for protecting a frequency selective surface according to one embodiment of the present disclosure includes a support portion 410 at least one end portion of the protection device (e.g., a left end portion of fig. 4), the support portion 410 being configured to be fixed to a bracket (e.g., a bracket 480 in fig. 4) via a mechanical connection; further, the protection device 400 for protecting a frequency selective surface according to one embodiment of the present disclosure further includes a bridge member extending between both end portions (e.g., end portions on both left and right sides) of the protection device 400, wherein a connection member 420 for connecting a middle portion of the frequency selective surface 470 is provided at a middle portion of the bridge member to connect the middle portion of the frequency selective surface (e.g., the frequency selective surface 470 of fig. 4) to the middle portion of the bridge member. In the technical solution according to the present disclosure, since the middle portion of the frequency selection surface 470 can be connected to the middle portion of the bridge member, the structural strength of the frequency selection surface 470 becomes large, thereby being able to serve the purpose of protecting the frequency selection surface 470. Here, the middle portion of the frequency selective surface 470 is not necessarily located in the middle of the frequency selective surface 470, and accordingly, the middle portion of the bridge member is not necessarily located in the middle of the bridge member. It will be understood by those skilled in the art that the middle portion or middle portion is merely an area, and can even be said to be the rest of the area except for the end portions (e.g., the left and right end portions). In the solution according to the present disclosure, it is sufficient that the middle portion of the frequency selection surface 470 can be connected to the middle portion of the bridge member via the connecting action of the connecting member 420, thereby increasing the overall rigidity of the frequency selection surface 470.
Further, the protection device 400 further includes a vibrator supporting portion 430 for vibrator mounting, which is configured between the supporting portion 410' and the connection member 420 and configured to support a vibrator on a side of the protection device 400 away from the frequency selection surface 470. The difference from the embodiment shown in fig. 2A and 2B is that the vibrator support part 430 for vibrator mounting included in the protection apparatus 400 for protecting a frequency selective surface shown in fig. 4 does not have to be a closed quadrangular structure, for example, having only three sides as shown in fig. 4, which also enables good support of the vibrator.
In the embodiment shown in fig. 4, the protection device 400 includes two vibrator support portions 430, and those skilled in the art will appreciate that other numbers of vibrator support portions 430 are possible. The height of the vibrator support portion 430 does not necessarily correspond to the height of the vibrator, and may be slightly lower than the height of the vibrator, for example.
Furthermore, the aforementioned protection means and support for protecting the frequency selective surface are respectively located on both sides of the frequency selective surface, but in other embodiments, the protection means and support for protecting the frequency selective surface may also be located on the same side of the frequency selective surface. Further, for example, a support beam 555 may be provided on the lower side thereof, the support beam 555 being provided on the side of the frequency selection surface 370 remote from the vibrator 332 (in fig. 3, for example, on the lower surface of the frequency selection surface 370) and configured to support the frequency selection surface 370. FIG. 5 shows a schematic view of a support beam 555 according to yet another embodiment of the present disclosure. As shown in fig. 5, in order to increase the rigidity of the frequency selection surface 370, a support beam 555 may be further provided thereunder, and both ends are connected to the antenna side brackets 380 by rivets. A plurality of support beams 555 are placed in the vertical direction of the antenna to enhance the rigidity of the frequency selective surface 370. As shown in fig. 3 and 5, the frequency selection surface 370 and the support beam 555 are connected and fixed to the frequency selection surface 370 through rivet holes 5551, the support beam 555 is further provided with a mounting interface 5552 connected to a radiating unit such as a vibrator, and a vibrator support or a structural member of a radome support can be mounted above the support beam 555, so as to support the radome and protect the vibrator. This requirement is contingent on practical needs. The protection device disclosed by the disclosure has the advantages of compact structure, strong universality and strong applicability, can save the cost of the die, and has certain economic value.
Furthermore, the present disclosure also proposes a protection assembly for protecting a frequency selective surface, said protection assembly comprising at least two protection devices according to the above, wherein said at least two protection devices are fixedly connected by a cross beam. Preferably, in one embodiment according to the present disclosure, the protection device and the cross member are integrally formed. Fig. 6 shows a schematic structural diagram of a protection device 600 for protecting a frequency selective surface according to yet another embodiment of the present disclosure. The previous embodiment is to reinforce the rigidity of the frequency selective surface 270 and to mount an element such as a radiation unit by mounting a plurality of single antenna protection devices 200, and the embodiment is to fuse a plurality of single antenna protection devices 200 into one large single antenna protection device 600. The combination, which is illustrated as a fusion of 3 sets, and is shown in fig. 6 as being fixedly connected by a cross beam 690, may be installed from the front of the frequency selective surface, which is not intended to limit the disclosure.
Still further, a third aspect of the present disclosure proposes an antenna, comprising: a support; a frequency selective surface; the protection device according to the first aspect of the present disclosure or the protection assembly according to the second aspect of the present disclosure, wherein the protection device or the protection assembly is configured for mechanical connection with the frequency selective surface at a middle portion thereof; and a first radiating element located on a first side of the frequency selective surface and a second radiating element located on a second side of the frequency selective surface opposite the first side. Preferably, in one embodiment according to the present disclosure, the protection device or protection assembly is further configured for crimping the frequency selective surface onto the bracket. Preferably, in one embodiment according to the present disclosure, the antenna further includes a support beam disposed on a side of the frequency selective surface remote from the protection device or the protection component and configured to support the frequency selective surface.
In view of the above, the inventors of the present disclosure have innovated that a protection device is provided for the frequency selection device, in which, since the intermediate portion of the frequency selection surface can be connected to the middle portion of the bridge member, the structural strength and rigidity of the frequency selection surface become large, thereby making it possible to achieve the purpose of protecting the frequency selection surface so that the frequency selection surface does not fail even in an outdoor long-term operation state and even in a vibration state.
The above description is only an alternative embodiment of the present disclosure and is not intended to limit the embodiment of the present disclosure, and various modifications and variations of the embodiment of the present disclosure may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the embodiments of the present disclosure should be included in the scope of protection of the embodiments of the present disclosure.
