Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a V-shaped antenna and a communication system. Background Art

[0002] With the development of wireless communication technology, the communication system can support more and more communication frequency bands, so the structure of the communication system antenna is becoming more and more complex, and the antenna integration is becoming higher and higher. However, due to the limitations of wind load and other conditions, it is difficult to further increase the front size of the antenna, resulting in a small number of integrated radiation units in the antenna, and the intensity and range of the radiated signal are also limited, making it difficult to improve the performance of the communication system. Summary of the invention

[0003] The present application provides a V-shaped antenna and a communication system, which optimizes the relationship between the windward surface and the radiation area. Adjacent V-shaped antenna brackets are less likely to cause signal shielding problems, which is beneficial to improving the gain of the communication system.

[0004] In a first aspect, the present application provides a communication system. The communication system includes a mounting frame and at least two antennas, wherein the at least two antennas are mounted on the mounting frame around the periphery of the mounting frame to cover the area around the periphery of the mounting frame. Among them: at least two antennas include V-shaped antennas, for example, some of the at least two antennas may be V-shaped antennas, or all of the at least two antennas may be V-shaped antennas. The V-shaped antenna includes two mounting plates, and a radiation unit array is mounted on the surface of each mounting plate on the side away from the mounting frame, and the planes where the two mounting plates are located intersect to form a V-shaped structure. A first angle is provided between the first mounting plate and the second mounting plate. Specifically, one of the two mounting plates has a first axis, and the other mounting plate has a second axis, and the first axis and the second axis are perpendicular to the center line of the mounting frame extending along the axis. A first angle β is provided between the first axis and the second axis, and the first angle β is less than or equal to 150°. The V-shaped antenna occupies a smaller area of ​​the windward surface, and more radiation units can be arranged, thereby maximizing the optimization of the relationship between the windward surface and the radiation area. In addition, adjacent V-shaped antenna brackets are not prone to signal shielding problems, which is conducive to improving the gain of the communication system.

[0005] In an optional technical solution, the first angle β can be 60° or 120°. Then, the shielding between adjacent antennas can be minimized, which is beneficial to improving the gain of the communication system. It is also beneficial to achieve coordination between different V-shaped antennas in the communication system to serve different cells.

[0006] Specifically, the two mounting plates of a V-shaped antenna have the same area, which is helpful to simplify the design of the V-shaped antenna and the control of the radiation signal.

[0007] When the V-shaped antenna is mounted on the mounting frame, two mounting plates of the V-shaped antenna are symmetrical about the first plane, and a center line of the mounting frame extending in the axial direction is located on the first plane.

[0008] In a specific technical solution, the V-shaped antenna includes a first V-shaped antenna, a second V-shaped antenna and a third V-shaped antenna. Among them; the mounting plate of the first V-shaped antenna includes a first mounting plate and a second mounting plate, the surface of the first mounting plate is mounted with a first radiation unit array, and the surface of the second mounting plate is mounted with a second radiation unit array; the mounting plate of the second V-shaped antenna includes a third mounting plate and a fourth mounting plate, the surface of the third mounting plate is mounted with a third radiation unit array, and the surface of the fourth mounting plate is mounted with a fourth radiation unit array; the mounting plate of the third V-shaped antenna includes a fifth mounting plate and a sixth mounting plate, the surface of the fifth mounting plate is mounted with a fifth radiation unit array, and the surface of the sixth mounting plate is mounted with a sixth radiation unit array. By reasonably arranging the above-mentioned first V-shaped antenna, the second V-shaped antenna and the third V-shaped antenna, the three antennas can cover a 360° range around the mounting frame. And by controlling the coordination of the radiation unit arrays of different antennas, multiple collaborative working modes can be provided.

[0009] When installing the first V-shaped antenna, the second V-shaped antenna and the third V-shaped antenna, the three V-shaped antennas can be evenly arranged around the mounting frame along the circumferential direction, so that the signal coverage is relatively uniform and the radiation signal generated by the antenna can be fully utilized.

[0010] In a specific working scenario, the first V-shaped antenna, the second V-shaped antenna and the third V-shaped antenna cooperate to cover three cells. Specifically, the signal radiated by the second radiation unit array and the signal radiated by the third radiation unit array cover the first cell; the signal radiated by the fourth radiation unit array and the signal radiated by the fifth radiation unit array cover the second cell; the signal radiated by the sixth radiation unit array and the signal radiated by the first radiation unit array cover the third cell. The three antennas in this solution are all V-shaped antennas, and there is less obstruction between the antennas, which is conducive to improving the gain of the communication system.

[0011] When the above working scenario is implemented, the second mounting plate is adjacent to the third mounting plate, the fourth mounting plate is adjacent to the fifth mounting plate, and the sixth mounting plate is adjacent to the first mounting plate. That is, the adjacent radiation units work together to cover the same cell, which is conducive to signal coordination, and is conducive to reducing signal shielding, and improving the signal coverage effect and strength in the cell.

[0012] In order to improve the signal coverage effect of each cell, the second mounting plate and the third mounting plate are parallel so that the normals of the second radiation unit array and the third radiation unit array are the same, which is beneficial to improving the uniformity of the signal in the coverage cell and increasing the coverage area of ​​the signal of the second radiation unit array and the third radiation unit array, or increasing the area of ​​the first cell. Similarly, the fourth mounting plate and the fifth mounting plate are parallel, and the sixth mounting plate and the first mounting plate are parallel. As a result, the signal uniformity in each cell is better and the signal coverage area is larger.

[0013] In another specific technical solution, the above-mentioned V-shaped antenna includes a fourth V-shaped antenna and a fifth V-shaped antenna. Among them; the mounting plate of the fourth V-shaped antenna includes a seventh mounting plate and an eighth mounting plate, the surface of the seventh mounting plate is mounted with a seventh radiation unit array, and the surface of the eighth mounting plate is mounted with an eighth radiation unit array. The mounting plate of the fifth V-shaped antenna includes a ninth mounting plate and a tenth mounting plate, the surface of the ninth mounting plate is mounted with a ninth radiation unit array, and the surface of the tenth mounting plate is mounted with a tenth radiation unit array. The signal radiated by the seventh radiation unit array covers the fourth cell, the signal radiated by the eighth radiation unit array and the signal radiated by the ninth radiation unit array cover the fifth cell, and the tenth radiation unit array covers the sixth cell. In this embodiment, three cells are covered by two V-shaped antennas, which is conducive to reducing the cost of the communication system.

[0014] The V-shaped antenna includes a circuit module, the circuit module includes multiple signal channels, a radiation unit array includes multiple radiation units, and a signal channel is connected to at least one radiation unit; the arrangement of the two radiation unit arrays that radiate signals covering the same cell is the same, and the connection relationship between the radiation units in the two radiation unit arrays and the signal channels is the same. In this solution, SRS channel estimation can be performed for the two radiation unit arrays respectively, which can realize the reuse of hardware resources and is conducive to reducing the cost of the V-shaped antenna.

[0015] In another technical solution, the arrangement of two radiating element arrays whose radiated signals cover the same cell is axisymmetric, and the connection relationship between the radiating elements in the two radiating element arrays and the signal channels is also axisymmetric. This solution is conducive to the joint signal estimation of the two radiating element arrays, and it is easy to design the A2B transformation matrix, thereby improving the channel estimation performance of the communication system. Among them, the A2B transformation matrix is ​​the transformation matrix from the antenna domain to the beam domain.

[0016] The driving relationship of two radiation unit arrays corresponding to the same cell can be the same or different. For example, in one technical solution, the arrangement of the two radiation unit arrays whose radiation signals cover the same cell is different, in one of the two radiation unit arrays, every N radiation units are connected to a signal channel; in the other of the two radiation unit arrays, some of the multiple radiation units are connected to a signal channel for every M radiation units, and some of the multiple radiation units are connected to a signal channel for every L radiation units; wherein M≠L.

[0017] In one technical solution, the radiated signal covers one of the two radiating element arrays in the same cell, and each O radiating elements are connected to a signal channel; in the other radiating element array of the two radiating element arrays, some of the radiating elements in the plurality of radiating elements are connected to a signal channel for each P radiating elements, where O≠P. Then the driving relationship in the two radiating element arrays 12 is different, which improves the flexibility of signal channel arrangement. Alternatively, in another technical solution, the above O=P, then the driving relationship of the two radiating element arrays is the same, and the same beam weights can be designed for the two radiating element arrays.

[0018] In order to improve the flexibility of the antenna, the V-shaped antenna includes a driving mechanism, which is connected to the two mounting plates respectively. The driving mechanism is used to drive the mounting plate to rotate around the mechanical downtilt rotation axis, so that the normal direction of the radiation element array on the mounting plate can be adjusted, and the coverage area of ​​the radiation element array can be adjusted. The mechanical downtilt rotation axis of each mounting plate is parallel to the corresponding mounting plate, so as to facilitate the control of the direction and angle of rotation of the mounting plate.

[0019] In a specific technical solution, the driving mechanism includes a first driving mechanism and a second driving mechanism, wherein the first driving mechanism is connected to a mounting plate of the V-shaped antenna and is used to drive the mounting plate to rotate around its mechanical downtilt rotation axis. The other driving mechanism is connected to another mounting plate of the V-shaped antenna and is used to drive the other mounting plate to rotate around its mechanical downtilt rotation axis. The mechanical downtilt of two mounting plates of a V-shaped antenna is decoupled, and when the mechanical downtilt of one mounting plate is adjusted, the other mounting plate can be mechanically tilted or remain stationary, or the angles or directions of the mechanical downtilt of the two mounting plates are different, etc.

[0020] Specifically, the mechanical tilt axis is perpendicular to the center line of the mounting frame extending along the axis. When the mounting plate rotates around the mechanical tilt axis, a certain positional relationship between the mounting plate and the mounting frame can be ensured, and the mounting plate does not deflect along the direction of the mechanical tilt axis.

[0021] In a specific technical solution, the mounting plate is a square mounting plate, and the mechanical tilt rotation axis is parallel to at least one side of the square mounting plate. For example, the mechanical tilt rotation axis is parallel to the top side or the bottom side of the square mounting plate.

[0022] In actual application, even if the angle of the mounting plate is adjusted by the driving mechanism, the mounting plates where the two radiating unit arrays of the same cell are located remain parallel, thereby maintaining a certain uniformity of the signal in a cell and covering a larger area.

[0023] The V-shaped antenna also includes a circuit module, which is connected to the radiation unit array and mounted on one side of the two mounting plates away from the radiation unit array. The circuit module and the mounting plate are integrated into an integral structure, which can realize the modularization of the V-shaped antenna.

[0024] In the second aspect, the present application also provides a V-shaped antenna, which is installed on a mounting frame. The V-shaped antenna includes two mounting plates, and a radiation unit array is installed on the surface of each mounting plate on the side facing away from the mounting frame, and the planes where the two mounting plates are located intersect to form a V-shaped structure. There is a first angle between the first mounting plate and the second mounting plate. Specifically, one of the two mounting plates has a first axis, and the other mounting plate has a second axis, and the first axis and the second axis are perpendicular to the center line of the mounting frame extending along the axis. There is a first angle β between the first axis and the second axis, and the first angle β is less than or equal to 150°. The V-shaped antenna occupies a smaller area of ​​the windward surface, and more radiation units can be arranged, which maximizes the optimization of the relationship between the windward surface and the radiation area. In addition, adjacent V-shaped antenna brackets are less prone to signal shielding problems, which is conducive to improving the gain of the communication system.

[0025] In an optional technical solution, the first angle β can be 60° or 120°. Then, the shielding between adjacent antennas can be minimized, which is beneficial to improving the gain of the communication system. It is also beneficial to achieve coordination between different V-shaped antennas in the communication system to serve different cells.

[0026] Specifically, the two mounting plates of a V-shaped antenna have the same area, which is helpful to simplify the design of the V-shaped antenna and the control of the radiation signal.

[0027] When the V-shaped antenna is mounted on the mounting frame, two mounting plates of the V-shaped antenna are symmetrical about the first plane, and a center line of the mounting frame extending in the axial direction is located on the first plane.

[0028] In order to improve the flexibility of the antenna, the V-shaped antenna includes a driving mechanism, which is connected to the two mounting plates respectively. The driving mechanism is used to drive the mounting plate to rotate around the mechanical downtilt rotation axis, so that the normal direction of the radiation element array on the mounting plate can be adjusted, and the coverage area of ​​the radiation element array can be adjusted. The mechanical downtilt rotation axis of each mounting plate is parallel to the corresponding mounting plate, so as to facilitate the control of the direction and angle of rotation of the mounting plate.

[0029] In a specific technical solution, the driving mechanism includes a first driving mechanism and a second driving mechanism, wherein the first driving mechanism is connected to a mounting plate of the V-shaped antenna and is used to drive the mounting plate to rotate around its mechanical downtilt rotation axis. The other driving mechanism is connected to another mounting plate of the V-shaped antenna and is used to drive the other mounting plate to rotate around its mechanical downtilt rotation axis. The mechanical downtilt of two mounting plates of a V-shaped antenna is decoupled, and when the mechanical downtilt of one mounting plate is adjusted, the other mounting plate can be mechanically tilted or remain stationary, or the angles or directions of the mechanical downtilt of the two mounting plates are different, etc.

[0030] Specifically, the mechanical tilt axis is perpendicular to the center line of the mounting frame extending along the axis. When the mounting plate rotates around the mechanical tilt axis, a certain positional relationship between the mounting plate and the mounting frame can be ensured, and the mounting plate does not deflect along the direction of the mechanical tilt axis.

[0031] In a specific technical solution, the mounting plate is a square mounting plate, and the mechanical tilt rotation axis is parallel to at least one side of the square mounting plate. For example, the mechanical tilt rotation axis is parallel to the top side or the bottom side of the square mounting plate.

[0032] The V-shaped antenna also includes a circuit module, which is connected to the radiation unit array and mounted on one side of the two mounting plates away from the radiation unit array. The circuit module and the mounting plate are integrated into an integral structure, which can realize the modularization of the V-shaped antenna. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] To facilitate understanding of the V-shaped antenna and communication system provided in the embodiments of the present application, the application scenarios thereof are introduced below. Figure 1 A schematic diagram of a communication system architecture applicable to the embodiment of the present application is shown as an example. Figure 1As shown, the communication system can be a base station antenna feed system. The application scenario may include a base station and a terminal. Wireless communication can be achieved between the base station and the terminal. The base station can be located in a base station subsystem (base station subsystem, BBS), a terrestrial radio access network (UMTSterrestrial radio access network, UTRAN) or an evolved terrestrial radio access network (evolveduniversal terrestrial radio access, E-UTRAN), and is used to provide cell coverage for wireless signals to achieve communication between terminal equipment and a wireless network. Specifically, the base station can be a base transceiver station (base transceiver station, BTS) in a global system for mobile communications (globalsystem for mobile communication, GSM) or (code division multiple access, CDMA) system, or a node B (NodeB, NB) in a wideband code division multiple access (wideband code division multiple access, WCDMA) system, or an evolutionary node B (evolutional NodeB, eNB or eNodeB) in a long term evolution (long term evolution, LTE) system, or a wireless controller in a cloud radio access network (cloud radio access network, CRAN) scenario. Alternatively, the base station may also be a relay station, an access point, a vehicle-mounted device, a wearable device, a g-node (gNodeB or gNB) in a new wireless (NR) system, or a base station in a future evolved network, etc., which is not limited in the embodiments of the present application.

[0073] In addition, the above-mentioned base station can be a macro base station or a micro base station, and the above-mentioned communication system can realize multi-point coordinated transmission between macro base stations and macro base stations, micro base stations and micro base stations, or macro base stations and micro base stations. In addition, the communication system in this application is used for low-frequency scenarios (sub 6G) and is also applicable to high-frequency scenarios (above 6G); in addition, it is also applicable to 4G, 5G or future mobile communication systems; it is applicable to single-transmission reception point (Single-TRP) or multi-transmission reception point (Multi-TRP) scenarios, and any of their derivative scenarios; it is applicable to the scenario of new radio access technology (NR) uplink transmission; it is applicable to the scenarios of homogeneous networks and heterogeneous networks.

[0074] Figure 2 A possible structural diagram of a communication system is shown. The base station antenna feeding system may generally include structures such as an antenna 100, a mounting bracket 200, and an antenna mounting member 300. Among them, the antenna 100 of the base station may include an antenna cover 110. The antenna cover 110 has good electromagnetic wave penetration characteristics in electrical performance and can withstand the influence of external harsh environments in mechanical performance, thereby protecting the antenna 100 from external environmental influences. The antenna 100 can be installed on the mounting bracket 200 through the antenna mounting member 300 to facilitate the reception or transmission of signals by the antenna 100. Of course, Figure 2 The embodiment shown is only an optional implementation method. In specific implementation, the antenna and base station antenna feeding system in the embodiment of the present application may be Figure 2 The embodiment shown.

[0075] In addition, the base station may further include a radio frequency processing unit 400 and a baseband processing unit 500. For example, the radio frequency processing unit 400 may be used to perform frequency selection, amplification, and down-conversion processing on the signal received by the antenna 100, and convert it into an intermediate frequency signal or a baseband signal and send it to the baseband processing unit 500, or the radio frequency processing unit 400 may be used to convert the baseband processing unit 500 or the intermediate frequency signal into an electromagnetic wave through the antenna 100 after up-conversion and amplification processing and send it out. The baseband processing unit 500 may be connected to the feeding network of the antenna 100 through the radio frequency processing unit 400. In some embodiments, the radio frequency processing unit 400 may also be referred to as a remote radio unit (RRU), or may also be a radio frequency module in an active antenna unit (AAU), and the baseband processing unit 500 may also be referred to as a baseband unit (BBU).

[0076] In a possible embodiment, Figure 2 As shown, the RF processing unit 400 can be integrally provided with the antenna 100, and the baseband processing unit 500 is located at the far end of the antenna 100. In some other embodiments, the RF processing unit 400 and the baseband processing unit 500 can also be located at the far end of the antenna 100 at the same time. The RF processing unit 400 and the baseband processing unit 500 can be connected via a cable 600.

[0077] More specifically, please refer to Figure 2 and Figure 3 , Figure 3 FIG. 1 is a schematic diagram of the composition of an antenna of a possible embodiment of the present application. Figure 3 As shown, the antenna 100 of the base station may include a radiation unit 120 and a reflector 130. The above-mentioned radiation unit 120 may also be referred to as an antenna vibrator, a vibrator, etc., which can effectively send or receive antenna signals. In the antenna 100, the frequencies of different radiation units 120 may be the same or different. The reflector 130 may also be referred to as a bottom plate, an antenna panel or a reflective surface, etc., which may be made of metal. When the antenna 100 receives a signal, the reflector 130 may reflect the antenna signal to the target coverage area. When the antenna 100 transmits a signal, the reflector 130 may reflect and transmit the signal incident on the reflector 130. The radiation unit 120 is usually placed on one side of the reflector 130, which can not only greatly enhance the receiving or transmitting capability of the antenna 100 signal, but also block and shield the interference of other radio waves from the back side of the reflector 130 (the back side of the reflector 130 in this application refers to the side opposite to the reflector 130 for setting the radiation unit 120) on the reception of the antenna signal.

[0078] In the antenna 100 of the base station, the radiation unit 120 is connected to the feed network 140. The feed network 140 is generally composed of a controlled impedance transmission line. The feed network 140 can feed the signal to the radiation unit 120 according to a certain amplitude and phase, or send the received signal to the baseband processing unit 500 of the base station according to a certain amplitude and phase. Specifically, in some embodiments, the feed network 140 can be used to achieve different radiation beam directions, or connected to a calibration network to obtain the calibration signal required by the system. A phase shifter may be included in the feed network 140 to change the phase of the antenna signal radiation. Some modules for expanding performance may also be set in the feed network 140, such as a combiner, which can be used to combine signals of different frequencies into one path and transmit them through the antenna 100; or when used in reverse, it can be used to divide the signal received by the antenna 100 into multiple paths according to different frequencies and transmit them to the baseband processing unit 500 for processing, and another example is a filter, which is used to filter out interference signals.

[0079] It is worth noting that the embodiments involving the word "specific", "specific settings" and "specific designs" that appear in this application all refer to optional embodiments, that is, the embodiment is a possible specific embodiment under the inventive concept of this application, but also includes other possible embodiments.

Figure 4 In the scheme shown, the above-mentioned communication system includes antennas 100 on the surrounding sides of the mounting frame 200, each antenna 100 is a planar antenna, and includes a planar mounting plate, on which a radiation unit is mounted. The number of radiation units arranged on a certain windward surface is small, and the system capacity gain is small. Figure 5 A schematic diagram of a communication system in the prior art is shown in FIG. Figure 5 As shown, in order to increase the capacity gain of the communication system, the antenna 100 in the communication system can also be a flag-mounted antenna, which includes two parallel mounting plates, which can reduce the area of ​​the windward surface and increase the number of radiation units in the system. However, there will be a problem of signal shielding between adjacent antennas, resulting in limited gain of the actual communication system. In addition, in this solution, interference is prone to occur between cells with different signal coverage.

The at least two antennas 100 include a V-shaped antenna 1. In an optional embodiment, the specific number of antennas 100 included in the communication system and the number of V-shaped antennas 1 included are not limited. Several possible embodiments are listed below for reference, for example Figure 6 As shown, in one embodiment, the communication system includes two antennas 100, one of the two antennas 100 is a V-shaped antenna 1, and the other antenna 100 can be a flag-mounted antenna.

[0082] When the V-shaped antenna 1 is mounted on the mounting frame 200, the antenna mounting member 300 can be used to connect the V-shaped antenna 1 and the mounting frame 200. In one embodiment, the antenna mounting member 300 is a Y-shaped structure. Specifically, one end of the antenna mounting member 300 includes two branches, and the two branches are respectively connected to the two mounting plates 11 in a one-to-one correspondence, and the other end is connected to the mounting frame 200, so that the V-shaped antenna 1 can be mounted on the mounting frame 200 more stably and reliably.

Fig. 9 As shown, in one embodiment, the V-shaped antenna 1 provided in the present application includes two mounting plates 11, and a radiation unit array 12 is installed on the surface of each mounting plate 11 on the side facing away from the mounting frame 200 to form two antenna panels. A radiation unit array 12 includes a plurality of radiation units. The planes where the above-mentioned two mounting plates 11 are located intersect, and the angle between the above-mentioned two mounting plates 11 is a first angle β.

Specifically, the V-shaped antenna 1 includes a total of two mounting plates 11 for setting the radiation unit array 12, and the two mounting plates 11 form a V-shaped structure, or a substantially V-shaped structure, and the radiation unit array 12 is arranged on the outer surface of the V-shaped structure. There can be multiple ways to determine the above-mentioned first angle β. In one determination method, the angle between the planes where the two mounting plates 11 are located can be used as the first angle β; or, in one determination method, one of the two mounting plates 11 has a first axis, and the other mounting plate 11 has a second axis, the first axis and the second axis are perpendicular to the center line of the mounting frame 200 extending along the axis, and the angle between the first axis and the second axis is the first angle β. Alternatively, in another determination method, both mounting plates 11 are rectangular mounting plates 11, and at least one set of sides of the two mounting plates 11 are parallel, for example, the long side of one mounting plate 11 of the two mounting plates 11 is parallel to the long side of the other mounting plate 11, and is parallel to the center line of the mounting frame 200 extending along the axis. The angle between the short side of one mounting plate 11 of the two mounting plates 11 and the short sides of the two mounting plates 11 is the first angle β. When the mounting plates 11 are all square mounting plates, the long side and the short side are not distinguished, and the two perpendicular sides of the square mounting plate can be considered to be equivalent to the long side and the short side, respectively. When the mounting plate 11 is a rectangular mounting plate, the first axis may be parallel to one side of the corresponding mounting plate 11 , and the second axis may be parallel to one side of the corresponding mounting plate 11 .

[0084] In the embodiment of the present application, a V-shaped antenna 1 is provided. The V-shaped antenna 1 occupies a smaller area of ​​the windward surface and can arrange more radiation units, thereby maximizing the relationship between the windward surface and the radiation area. Figure 8The adjacent V-shaped antenna 1 bracket is not prone to signal shielding, which is beneficial to improving the gain of the communication system.

[0085] In one embodiment, the mounting plate 11 includes a reflector 130, that is, the mounting plate 11 is used not only to mount the radiation unit 120, but also to reflect the signal of the radiation unit as the reflector 130. For example, the mounting plate 11 itself can be a structure made of metal material, etc., so that it can serve as the reflector 130; or, the reflector 130 can be prepared by coating a reflective material layer on the surface of the mounting plate 11.

[0086] In a specific embodiment, the first angle β is 60° or 120°. Figure 8 In the illustrated embodiment, in a typical application scenario, the communication system includes three V-shaped antennas 1 evenly arranged around the mounting frame 200. The shielding between adjacent antennas 100 can be minimized, which is beneficial to improving the gain of the communication system. It is also beneficial to achieve coordination between different V-shaped antennas 1 in the communication system to serve different cells.

[0087] In an optional embodiment, the shapes and areas of the two mounting plates 11 of a V-shaped antenna 1 may be the same or different. In a specific embodiment, the shapes and areas of the two mounting plates 11 of a V-shaped antenna 1 are the same, so that the structure of the V-shaped antenna 1 is more regular, and the antenna radiation unit array 12 is arranged, which is conducive to simplifying the control of the antenna 100.

[0088] When the V-shaped antenna 1 is mounted on the mounting frame 200, there are multiple options for the positional relationship between the V-shaped antenna 1 and the mounting frame 200, and the V-shaped antenna 1 can be arranged according to the signal coverage requirements. Figure 8 As shown, in one application scenario, two mounting plates 11 of a V-shaped antenna 1 are symmetrical about a first plane, and the center line of the mounting frame 200 extending axially is located in the first plane. Two mounting plates 11 of a V-shaped antenna 1 are also symmetrical about the center line of the mounting frame 200 extending axially.

[0089] In one embodiment, the multiple V-shaped antennas 1 in the communication system are evenly arranged around the circumference of the mounting frame 200 , thereby facilitating improving the uniformity of the signals of the multiple V-shaped antennas 1 within the coverage range.

[0090] For ease of description, it is considered Figure 8The three V-shaped antennas 1 included in the communication system shown are respectively a first V-shaped antenna 13, a second V-shaped antenna 14 and a third V-shaped antenna 15. Among them, the mounting plate 11 of the first V-shaped antenna 13 includes a first mounting plate 131 and a second mounting plate 132, the surface of the first mounting plate 131 is mounted with a first radiation element array, and the surface of the second mounting plate 132 is mounted with a second radiation element array; the mounting plate 11 of the second V-shaped antenna 14 includes a third mounting plate 141 and a fourth mounting plate 142, the surface of the third mounting plate 141 is mounted with a third radiation element array, and the surface of the fourth mounting plate 142 is mounted with a fourth radiation element array; the mounting plate 11 of the third V-shaped antenna 15 includes a fifth mounting plate 151 and a sixth mounting plate 152, the surface of the fifth mounting plate 151 is mounted with a fifth radiation element array, and the surface of the sixth mounting plate 152 is mounted with a sixth radiation element array.

[0091] Fig.10 A schematic diagram of the structure of the communication system in the embodiment of the present application is shown in FIG. Fig.10 As shown, in the actual working process, the antenna 100 can have multiple networking forms. In a typical networking form, the signal radiated by the second radiation element array on the second mounting plate 132 and the signal radiated by the third radiation element array on the third mounting plate 141 cover the first cell, that is, the second radiation element array and the third radiation element array correspond to one cell; the signal radiated by the fourth radiation element array on the fourth mounting plate 142 and the signal radiated by the fifth radiation element array on the fifth mounting plate 151 cover the second cell. That is, the fourth radiation element array and the fifth radiation element array correspond to one cell; the signal radiated by the sixth radiation element array on the sixth mounting plate 152 and the signal radiated by the first radiation element array on the first mounting plate 131 cover the third cell, and the sixth radiation element array and the first radiation element array correspond to one cell. In order to realize the above functions, the second radiation element array and the third radiation element array work together, the fourth radiation element array and the fifth radiation element array work together, and the sixth radiation element array and the first radiation element array work together.

[0092] When the three V-shaped antennas 1 of the communication system are specifically arranged, the second mounting plate 132 is adjacent to the third mounting plate 141, the fourth mounting plate 142 is adjacent to the fifth mounting plate 151, and the sixth mounting plate 152 is adjacent to the first mounting plate 131. Thus, the two radiation unit arrays 12 corresponding to the same cell are adjacent, which is conducive to the coordination between the two, and is conducive to reducing signal shielding and improving the signal coverage effect and strength in the cell.

[0093] In addition, the second mounting plate 132 and the third mounting plate 141 are parallel, so that the normal directions of the second radiation unit array and the third radiation unit array are the same, which is conducive to improving the uniformity of the signal in the coverage area, and is conducive to increasing the coverage area of ​​the signal of the second radiation unit array and the third radiation unit array, or increasing the area of ​​the first area. Similarly, the fourth mounting plate 142 and the fifth mounting plate 151 are parallel, so that the normal directions of the fourth radiation unit array and the fifth radiation unit array are the same, which is conducive to improving the uniformity of the signal in the coverage area, and is conducive to increasing the coverage area of ​​the signal of the fourth radiation unit array and the fifth radiation unit array, or increasing the area of ​​the second area. The sixth mounting plate 152 and the first mounting plate 131 are parallel, so that the normal directions of the sixth radiation unit array and the first radiation unit array are the same, which is conducive to improving the uniformity of the signal in the coverage area, and is conducive to increasing the coverage area of ​​the signal of the sixth radiation unit array and the first radiation unit array, or increasing the area of ​​the third area.

[0094] In one embodiment, the first angle β of the three V-shaped antennas 1 is 60°, and the three V-shaped antennas 1 are evenly arranged around the mounting frame 200. The communication system serves three cells, so that the three cells are equally divided along the circumference, and each cell covers a range of 120°. In other embodiments, the three cells may not be evenly arranged around the mounting frame 200, or at least one of the V-shaped antennas 1 is not symmetrically arranged relative to the mounting frame 200, so that the signal strength of individual cells can be enhanced in a targeted manner.

[0095] Fig.11 A schematic diagram of the structure of the communication system in the embodiment of the present application is shown in FIG. Fig.11 As shown, in another embodiment, the V-shaped antenna 1 included in the communication system includes a fourth V-shaped antenna 16 and a fifth V-shaped antenna 17. Among them; the mounting plate 11 of the fourth V-shaped antenna 16 includes a seventh mounting plate 161 and an eighth mounting plate 162, the surface of the seventh mounting plate 161 is mounted with a seventh radiation element array, and the surface of the eighth mounting plate 162 is mounted with an eighth radiation element array; the mounting plate 11 of the fifth V-shaped antenna 17 includes a ninth mounting plate 171 and a tenth mounting plate 172, the surface of the ninth mounting plate 171 is mounted with a ninth radiation element array, and the surface of the tenth mounting plate 172 is mounted with a tenth radiation element array. In specific operation, the signal radiated by the seventh radiation element array on the seventh mounting plate 161 covers the fourth cell, the signal radiated by the eighth radiation element array on the eighth mounting plate 162 and the signal radiated by the ninth radiation element array on the ninth mounting plate 171 cover the fifth cell, and the tenth radiation element array on the tenth mounting plate 172 covers the sixth cell. In this embodiment, two V-shaped antennas 1 are used to cover three cells.

[0096] It is worth noting that, in addition to the fourth V-shaped antenna 16 and the fifth V-shaped antenna 17, the communication system may include other antennas or may not include other antennas. For example, the communication system may only include the fourth V-shaped antenna 16 and the fifth V-shaped antenna 17; or, in addition to the fourth V-shaped antenna 16 and the fifth V-shaped antenna 17, the communication system may also include one antenna 100, two antennas 100, or a greater number of antennas 100. In addition, in addition to the fourth V-shaped antenna 16 and the fifth V-shaped antenna 17, the communication system may include the V-shaped antenna 1, a flag antenna, or a planar antenna.

[0097] In order to realize the working process of the V-shaped antenna 1, the V-shaped antenna 1 in the embodiment of the present application also includes a circuit module 18, which can also be called a radio frequency board. The above-mentioned circuit module 18 is connected to the radiation unit of the radiation unit array 12, so that the signals transmitted or received by the radiation unit can be processed and transmitted by the circuit module 18. In one embodiment, the circuit module 18 and the mounting plate 11 can be fixed to each other, so that the V-shaped antenna 1 can be formed into a module with certain functions, the modularization of the V-shaped antenna 1 can be realized, and the process of installing the V-shaped antenna 1 in the communication system can be simplified.

[0098] Figure 12 to Figure 15 Schematic diagrams of several structures of V-shaped antennas in the embodiments of the present application, such as Figure 12 to Figure 15 As shown, the V-shaped antenna has a V-shaped bracket on the side away from the radiation unit array, and a V-shaped accommodating cavity is formed between the V-shaped bracket and the mounting plate, and the circuit module 18 is arranged in the above-mentioned V-shaped accommodating cavity. Specifically, there are multiple options for the position of the circuit module 18 of the V-shaped antenna 1. For example, when installing the above-mentioned circuit module 18, the circuit module 18 can be installed on the side of the two mounting plates 11 away from the radiation unit array 12, thereby reducing the influence of the circuit module 18 on the signal of the radiation unit, and the two mounting plates 11 of the V-shaped antenna 1 have a certain accommodating space on the side away from the radiation unit array 12 for installing the above-mentioned circuit module 18. Figure 12 to Figure 14 As shown, in an optional embodiment, the V-shaped antenna 1 may include a circuit module 18, and the circuit module 18 is connected to the two mounting plates 11 respectively, and may be connected to different positions of the two mounting plates 11. For example, the widths of the two mounting plates 11 of a V-shaped antenna 1 are the same. Fig.12 As shown, in one embodiment, both ends of the circuit module 18 are connected to two mounting plates 11, and the connection points between the circuit module 18 and the mounting plates 11 are symmetrically arranged. Fig.12 In the equation, d1=d2,d3=d4. Fig.13As shown, in one embodiment, the two ends of the circuit module 18 are connected to the two mounting plates 11 respectively, and the two ends of the circuit module 18 are in a centrally symmetrical relationship with the connection points of the two mounting plates 11, such as Fig.13 In the equation, d1=d4,d2=d3. Fig.14 As shown, in one embodiment, the two ends of the circuit module 18 are connected to the head and tail of the two mounting plates 11 respectively. Fig.14 As shown, one end of the circuit module 18 is connected to an end of one mounting board 11 away from another mounting board 11, and the other end is connected to an end of the other mounting board 11 toward the one mounting board 11. Fig.15 As shown, in one embodiment, the V-shaped antenna 1 may further include two circuit modules 18 , one of the two circuit modules 18 is connected to one of the two mounting plates 11 of the V-shaped antenna 1 , and the other circuit module 18 is connected to the other mounting plate 11 .

[0099] Figure 16 to Figure 18 Schematic diagrams of several structures of V-shaped antennas in the embodiments of the present application, such as Figure 16 to Figure 18 As shown, the V-shaped antenna has a flat bracket on one side away from the radiation unit array, and a triangular accommodating cavity is formed between the flat bracket and the mounting plate. The circuit module 18 is arranged in the triangular accommodating cavity. Specifically, the circuit module 18 is fixed to the flat bracket, which is conducive to improving the heat dissipation effect of the circuit module. Specifically, there are multiple options for the connection position of the circuit module 18 and the radiation unit arrays of the two mounting plates. For example, Fig.16 As shown, the two ends of the circuit module 18 are connected to the first and the second ends of the two mounting boards 11 respectively; or as shown in FIG. Fig.17 As shown, the two ends of the circuit module 18 are connected to the tails of the two mounting plates 11 respectively; or Fig.18 As shown, two ends of the circuit module 18 are connected to the middle parts of the two mounting plates 11 respectively.

[0100] In a specific embodiment, a circuit module 18 includes multiple signal channels, a radiation element array 12 includes multiple radiation elements, and a signal channel is connected to at least one radiation element. Then a signal channel can be connected to one radiation element or to two or more radiation elements.

[0101] Fig.19 is a schematic diagram of a radiation unit array in an embodiment of the present application, such as Fig.19As shown, in one embodiment, the arrangement of the two radiation unit arrays 12 radiating signals covering the same cell is the same, and the connection relationship between the radiation units in the two radiation unit arrays 12 and the signal channels is the same. It can be understood that the two radiation unit arrays 12 corresponding to the same cell are equivalent to a translation relationship, the arrangement of the radiation units is the same, and the connection relationship between the radiation units and the signal channels is also the same. In this solution, SRS channel estimation can be performed for the two radiation unit arrays 12 separately, and hardware resources can be reused, which is conducive to reducing the cost of the V-shaped antenna 1.

[0102] Specifically, Fig.19 As shown, the radiation element array 12 in the figure is a matrix of 10 columns and 24 rows, which is a triangular array of 128T DBF. The adjacent crosses of the same color in the vertical direction indicate that the radiation elements are connected by a channel. For the convenience of description, this connection relationship of 1 channel corresponding to multiple arrays is called a driving relationship. If a channel connects 10 arrays, it is called 1 drive 10. The radiation element array 12 on a mounting plate 11 in the figure includes two driving relationships: 1 drive 6 and 1 drive 12. Specifically, the first two columns and the last two columns on the panel each have 2 channels, and the middle 6 columns each contain 4 channels.

[0103] Fig. 20 is a schematic diagram of a radiation unit array in an embodiment of the present application, such as Fig. 20 As shown, in another embodiment, the arrangement of the two radiation element arrays 12 whose radiated signals cover the same cell is axially symmetrical, and the connection relationship between the radiation elements in the two radiation element arrays 12 and the signal channels is also axially symmetrical. It can be understood that the two radiation element arrays 12 corresponding to the same cell are equivalent to a mirror relationship. This scheme is conducive to the joint signal estimation of the two radiation element arrays 12, and it is easy to design the A2B transformation matrix, thereby improving the channel estimation performance of the communication system. Among them, the A2B transformation matrix is ​​the transformation matrix from the antenna domain to the beam domain.

[0104] Specifically, Fig. 20 As shown, the radiation element array 12 in the figure is a matrix of 11 columns and 24 rows, which is a triangular array of 128T DBF. The adjacent crosses of the same color in the vertical direction indicate that the radiation elements are connected by a channel. The radiation element array 12 on a mounting plate 11 in the figure includes two driving relationships: 1 drive 6 and 1 drive 12.

[0105] Fig.21 is a schematic diagram of a radiation unit array in an embodiment of the present application, such as Fig.21As shown, in a specific embodiment, the arrangement of two radiation element arrays 12 whose radiated signals cover the same cell is different. In one of the two radiation element arrays 12, every N radiation elements are connected to a signal channel, that is, there is a 1-drive-N driving relationship. In another of the two radiation element arrays 12, some of the multiple radiation elements are connected to a signal channel for every M radiation elements, and some of the multiple radiation elements are connected to a signal channel for every L radiation elements, and M≠L, that is, there are two driving relationships, 1-drive-M and 1-drive-L. Then the driving relationships of the two radiation element arrays 12 corresponding to the same cell may be different.

[0106] Specifically, Fig.21 As shown, the radiation element array 12 in the figure is a matrix of 11 columns and 24 rows, which is a triangular array of 128T DBF. Crosses of the same color adjacent to each other in the vertical direction indicate that the radiation elements are connected by a channel. In the figure, the radiation element array 12 on a mounting plate 11 (left side) is a 1-drive-12 driving relationship, and the radiation element array 12 on another mounting plate 11 (right side) includes two driving relationships: 1-drive-6 and 1-drive-12. That is, N=6, M=6, L=12, and in this embodiment, N=M. In other embodiments, N≠L and N≠M can also be made.

[0107] In a specific embodiment, the two radiation element arrays 12 of the two radiation element arrays 12 whose radiated signals cover the same cell may respectively have a driving relationship. Each radiation element array 12 has a driving relationship, which makes it easier to design weights. For example, in one of the two radiation element arrays 12 whose radiated signals cover the same cell, every O radiation elements are connected to a signal channel, that is, there is a driving relationship of 1 driving O. In the other radiation element array 12 of the two radiation element arrays 12, every P radiation elements are connected to a signal channel, that is, there is a driving relationship of 1 driving P. In one embodiment, the above O≠P, then the driving relationships in the two radiation element arrays 12 are different, which improves the flexibility of signal channel arrangement. In another embodiment, the above O=P, then the driving relationship of the two radiation element arrays 12 is the same, and the same beam weights can be designed for the two radiation element arrays 12.

[0108] Fig. 22 Schematic diagram of mechanical downtilt of a V-shaped antenna in an embodiment of the present application, such as Fig. 22As shown, in one embodiment, in order to improve the performance of the V-shaped antenna 1, in the embodiment of the present application, the V-shaped antenna 1 may also include a driving mechanism 19, and the driving mechanism 19 is respectively connected to the two mounting plates 11, and the driving mechanism 19 is used to drive the mounting plate 11 to rotate around a mechanical downtilt rotation axis 191, and the mechanical downtilt rotation axis 191 of each mounting plate 11 is parallel to the corresponding mounting plate 11. In one embodiment, the above-mentioned mechanical downtilt rotation axis 191 may be located in the plane where the mounting plate 11 is located, or the above-mentioned mechanical downtilt rotation axis 191 may also be located outside the plane where the above-mentioned mounting plate 11 is located. In this solution, by adjusting the mechanical downtilt of the mounting plate 11, the normal direction of the radiation unit array 12 can be adjusted, thereby adjusting the area covered by the radiation unit signal and the signal strength for different areas, enriching the application scenarios of the communication system.

[0109] In order to realize the rotation of the mounting plate 11 , the mounting plate 11 may be rotatably mounted relative to the antenna mounting component 300 .

[0110] In other embodiments, the driving mechanism 19 may be connected to only one mounting plate 11 to drive the mounting plate 11 to rotate around the mechanical downtilt rotation axis 191 to meet specific application requirements of the V-shaped antenna 1 .

[0111] In addition, in one embodiment, the driving mechanism 19 includes a first driving mechanism and a second driving mechanism, wherein the first driving mechanism is connected to a mounting plate 11 of the V-shaped antenna 1, and is used to drive the mounting plate 11 to rotate around its mechanical downtilt rotation axis 191; the other driving mechanism is connected to another mounting plate 11 of the V-shaped antenna 1, and is used to drive the other mounting plate 11 to rotate around the mechanical downtilt rotation axis 191. In this embodiment, the mechanical downtilt of the two mounting plates 11 of a V-shaped antenna 1 is decoupled, and when the mechanical downtilt of one mounting plate 11 is adjusted, the other mounting plate 11 can be mechanically tilted or kept stationary, or the angles or directions of the mechanical downtilts of the two mounting plates are different, etc.

[0112] In an embodiment, a driving mechanism 19 may be used to drive the two mounting plates 11 to mechanically tilt downward, thereby simplifying the structure of the V-shaped antenna 1 and reducing the cost of the V-shaped antenna 1 .

[0113] In a specific embodiment, the mechanical tilt rotation axis 191 is perpendicular to the center line of the mounting frame 200 extending along the axis. When the mounting plate 11 rotates around the mechanical tilt axis, it can be ensured that there is a certain positional relationship between the mounting plate 11 and the mounting frame 200, and the mounting plate 11 does not deflect along the direction of the mechanical tilt rotation axis 191. In one embodiment, the mechanical tilt axis of one mounting plate 11 is parallel to the first axis, and the mechanical tilt axis of another mounting plate 11 is parallel to the second axis.

[0114] When the mounting plate 11 of the V-shaped antenna 1 is a square mounting plate 11, for example, the mounting plate 11 can be a rectangular mounting plate 11 or a square mounting plate 11. The mechanical downward tilt rotation axis 191 is parallel to at least one side of the square mounting plate 11. For example, the mounting plate 11 is a rectangular mounting plate 11, and the long side of one mounting plate 11 of the two mounting plates 11 is parallel to the long side of the other mounting plate 11, and is parallel to the center line extending along the axis of the mounting frame 200. Then the mechanical downward tilt rotation axis 191 is parallel to the short side of the square mounting plate 11. Alternatively, the above-mentioned mechanical downward tilt rotation axis 191 is parallel to the top side or the bottom side of the square mounting plate 11.

[0115] In a specific application, the above-mentioned driving mechanism 19 drives the radiated signal to cover the mounting plates 11 where the two radiating unit arrays 12 of the same cell are located to remain parallel. In this solution, the signal in a cell can be kept uniform to a certain extent, and the coverage area is large. In addition, according to actual needs, the signal driven by the driving mechanism 19 to radiate the signal to cover the mounting plates 11 where the two radiating unit arrays 12 of the same cell are located can be kept parallel to each other, and have a certain angle, so as to improve the signal coverage strength of some areas in a targeted manner.

[0116] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
