V-shaped antenna and communication system

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on October 31, 2023, with application number 202311438423.7 and invention name "A V-shaped antenna and communication system", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a V-shaped antenna and a communication system. Background Art

[0004] With the advancement of wireless communication technology, communication systems are able to support more and more frequency bands. Consequently, the antenna structures of communication systems are becoming increasingly complex, and the antenna integration is becoming increasingly high. However, due to limitations such as wind load, it is difficult to further increase the frontal size of the antenna. As a result, the number of integrated radiating elements in the antenna is small, which limits the strength and range of the radiated signal, making it difficult to improve the performance of the communication system.

[0005] Summary of the Invention

[0006] The present application provides a V-shaped antenna and 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 blocking problems, which is conducive to improving the gain of the communication system.

[0007] In a first aspect, the present application provides a communications system. The communications system includes a mounting frame and at least two antennas, which are mounted on the mounting frame around a perimeter of the mounting frame to cover the area around the mounting frame. The at least two antennas include V-shaped antennas. For example, some or all of the at least two antennas may be V-shaped antennas. The V-shaped antenna includes two mounting plates, each with an array of radiating elements mounted on a surface facing away from the mounting frame. The planes of the two mounting plates intersect, forming a V-shaped structure. A first angle is defined between the first and second mounting plates. Specifically, one of the two mounting plates has a first axis, and the other has a second axis. The first and second axes are perpendicular to a centerline of the mounting frame extending along the axis. A first angle β is defined between the first and second axes, and the first angle β is less than or equal to 150°. The V-shaped antenna occupies a smaller windward surface area and can accommodate a larger number of radiating elements, thereby maximizing the relationship between the windward surface and the radiation area. Furthermore, adjacent V-shaped antenna supports are less prone to signal obstruction, which helps improve the gain of the communication system.

[0008] In an optional technical solution, the first angle β can be 60° or 120°. This minimizes occlusion between adjacent antennas, improving the gain of the communication system. This also facilitates collaboration between different V-shaped antennas in the communication system to serve different cells.

[0009] Specifically, the two mounting plates of a V-shaped antenna have the same area, which is beneficial for simplifying the design of the V-shaped antenna and the control of the radiation signal.

[0010] When the V-shaped antenna is mounted on the mounting bracket, the two mounting plates of the V-shaped antenna are symmetrical about the first plane, and the center line of the mounting bracket extending in the axial direction is located on the first plane.

[0011] In a specific technical solution, a V-shaped antenna includes a first V-shaped antenna, a second V-shaped antenna, and a third V-shaped antenna. The mounting plate for the first V-shaped antenna includes a first mounting plate and a second mounting plate, with a first radiating element array mounted on the surface of the first mounting plate and a second radiating element array mounted on the surface of the second mounting plate. The mounting plate for the second V-shaped antenna includes a third mounting plate and a fourth mounting plate, with a third radiating element array mounted on the surface of the third mounting plate and a fourth radiating element array mounted on the surface of the fourth mounting plate. The mounting plate for the third V-shaped antenna includes a fifth mounting plate and a sixth mounting plate, with a fifth radiating element array mounted on the surface of the fifth mounting plate and a sixth radiating element array mounted on the surface of the sixth mounting plate. By rationally arranging the first, second, and third V-shaped antennas, the three antennas can provide 360-degree coverage around the mounting frame. By controlling the coordination of the radiating element arrays of different antennas, multiple collaborative working modes can be achieved.

[0012] 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 circumferentially around the mounting frame, thereby achieving more uniform signal coverage and fully utilizing the radiation signals generated by the antennas.

[0013] In one specific operating scenario, the first, second, and third V-shaped antennas collaborate to cover three cells. Specifically, the signals radiated by the second and third radiating element arrays cover the first cell; the signals radiated by the fourth and fifth radiating element arrays cover the second cell; and the signals radiated by the sixth and first radiating element arrays cover the third cell. All three antennas in this solution are V-shaped, minimizing inter-antenna interference and improving the gain of the communication system.

[0014] In the specific implementation of the above working scenario, 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 radiating units work together to cover the same cell, which is conducive to achieving signal coordination, reducing signal obstruction, and improving the signal coverage and strength within the cell.

[0015] To improve signal coverage in each cell, the second and third mounting plates are parallel, aligning the normals of the second and third radiating element arrays. This improves signal uniformity within the cell and increases the signal coverage area of ​​the second and third radiating element arrays, or in other words, the area of ​​the first cell. Similarly, the fourth and fifth mounting plates are parallel, and the sixth mounting plate is parallel to the first. This improves signal uniformity within each cell and expands the signal coverage area.

[0016] In another specific technical solution, the V-shaped antenna includes a fourth V-shaped antenna and a fifth V-shaped antenna. Specifically, 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 being mounted with a seventh radiating element array, and the surface of the eighth mounting plate being mounted with an eighth radiating element 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 being mounted with a ninth radiating element array, and the surface of the tenth mounting plate being mounted with a tenth radiating element array. The signal radiated by the seventh radiating element array covers the fourth cell, the signals radiated by the eighth radiating element array and the ninth radiating element array cover the fifth cell, and the tenth radiating element array covers the sixth cell. In this embodiment, three cells are covered using two V-shaped antennas, which helps reduce the cost of the communication system.

[0017] The V-shaped antenna includes a circuit module, which includes multiple signal channels. A radiating element array includes multiple radiating elements, and a signal channel is connected to at least one radiating element. The two radiating element arrays radiating signals covering the same cell are arranged identically, and the radiating elements in both arrays have the same connection relationship with the signal channels. This solution allows for separate SRS channel estimation for both radiating element arrays, enabling hardware resource reuse and reducing the cost of the V-shaped antenna.

[0018] In another technical solution, two radiating element arrays whose radiated signals cover the same cell are arranged in an axisymmetric manner, and the connections between the radiating elements and the signal channels in the two radiating element arrays are also axisymmetric. This solution facilitates joint signal estimation of the two radiating element arrays and facilitates the design of the A2B transformation matrix, thereby improving the channel estimation performance of the communication system. The A2B transformation matrix is ​​the transformation matrix from the antenna domain to the beam domain.

[0019] The driving relationship between two radiating element arrays corresponding to the same cell can be the same or different. For example, in one technical solution, the arrangement of the two radiating element arrays whose radiated signals cover the same cell is different. In one of the two radiating element arrays, every N radiating elements are connected to a signal channel; in the other of the two radiating element arrays, every M radiating elements of some of the multiple radiating elements are connected to a signal channel, and every L radiating elements of some of the multiple radiating elements are connected to a signal channel; wherein M≠L.

[0020] In one technical solution, the radiated signal covers one of two radiating element arrays in the same cell, with each O radiating element connected to a signal channel. In the other radiating element array, some of the multiple radiating elements are connected to a signal channel with each P radiating element connected, where O ≠ P. This results in different drive relationships in the two radiating element arrays 12, increasing the flexibility of signal channel arrangement. Alternatively, in another technical solution, if O = P, the drive relationships of the two radiating element arrays are the same, and the same beam weights can be designed for both radiating element arrays.

[0021] To enhance antenna flexibility, the V-shaped antenna includes a drive mechanism connected to each of the two mounting plates. This mechanism rotates the mounting plates about a mechanical downtilt axis, thereby adjusting the normal orientation of the radiating element arrays on the mounting plates and adjusting their coverage area. The mechanical downtilt axis of each mounting plate is parallel to the corresponding mounting plate, facilitating control over the direction and angle of rotation.

[0022] In one specific technical solution, the drive mechanism includes a first drive mechanism and a second drive mechanism. The first drive mechanism is connected to one mounting plate of the V-shaped antenna and is configured to drive the first mounting plate to rotate about its mechanical downtilt axis. The second drive mechanism is connected to the other mounting plate of the V-shaped antenna and is configured to drive the other mounting plate to rotate about its mechanical downtilt axis. The mechanical downtilt of the two mounting plates of a V-shaped antenna is decoupled, allowing adjustment of the mechanical downtilt of one mounting plate while the other can be mechanically tilted or held stationary, or the two can be mechanically tilted at different angles or directions.

[0023] Specifically, the mechanical tilt axis is perpendicular to the centerline 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.

[0024] 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 or bottom side of the square mounting plate.

[0025] In actual applications, even when the angle of the mounting plate is adjusted using the drive mechanism, the mounting plates of the two radiating element arrays covering the same cell remain parallel. This ensures a certain degree of signal uniformity within a cell and a larger coverage area.

[0026] The V-shaped antenna also includes a circuit module connected to the radiating element array and mounted on the side of the two mounting plates facing away from the radiating element array. The circuit module and the mounting plates are integrated into a single structure, enabling modularization of the V-shaped antenna.

[0027] 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 facing away from the mounting frame, and the planes where the two mounting plates are located intersect, thereby forming 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, thereby maximizing the optimization of the relationship between the windward surface and the radiation area. In addition, the adjacent V-shaped antenna brackets are less prone to signal shielding problems, which is conducive to improving the gain of the communication system.

[0028] In an optional technical solution, the first angle β can be 60° or 120°. This minimizes occlusion between adjacent antennas, improving the gain of the communication system. This also facilitates collaboration between different V-shaped antennas in the communication system to serve different cells.

[0029] Specifically, the two mounting plates of a V-shaped antenna have the same area, which is beneficial for simplifying the design of the V-shaped antenna and the control of the radiation signal.

[0030] When the V-shaped antenna is mounted on the mounting bracket, the two mounting plates of the V-shaped antenna are symmetrical about the first plane, and the center line of the mounting bracket extending in the axial direction is located on the first plane.

[0031] To enhance antenna flexibility, the V-shaped antenna includes a drive mechanism connected to each of the two mounting plates. This mechanism rotates the mounting plates about a mechanical downtilt axis, thereby adjusting the normal orientation of the radiating element arrays on the mounting plates and adjusting their coverage area. The mechanical downtilt axis of each mounting plate is parallel to the corresponding mounting plate, facilitating control over the direction and angle of rotation.

[0032] In one specific technical solution, the drive mechanism includes a first drive mechanism and a second drive mechanism. The first drive mechanism is connected to one mounting plate of the V-shaped antenna and is configured to drive the first mounting plate to rotate about its mechanical downtilt axis. The second drive mechanism is connected to the other mounting plate of the V-shaped antenna and is configured to drive the other mounting plate to rotate about its mechanical downtilt axis. The mechanical downtilt of the two mounting plates of a V-shaped antenna is decoupled, allowing adjustment of the mechanical downtilt of one mounting plate while the other can be mechanically tilted or held stationary, or the two can be mechanically tilted at different angles or directions.

[0033] Specifically, the mechanical tilt axis is perpendicular to the centerline 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.

[0034] 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 or bottom side of the square mounting plate.

[0035] The V-shaped antenna also includes a circuit module connected to the radiating element array and mounted on the side of the two mounting plates facing away from the radiating element array. The circuit module and the mounting plates are integrated into a single structure, enabling modularization of the V-shaped antenna. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] In order to facilitate the understanding of the V-shaped antenna and communication system provided in the embodiment of the present application, its application scenario is introduced below. Figure 1 exemplarily shows a schematic diagram of a communication system architecture applicable to the embodiment of the present application. As shown in Figure 1, 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 (BBS), a terrestrial radio access network (UMTS terrestrial radio access network, UTRAN) or an evolved universal terrestrial radio access (E-UTRAN), and is used to provide cell coverage of wireless signals to achieve communication between terminal devices and wireless networks. Specifically, the base station can be a base transceiver station (BTS) in a global system for mobile communication (GSM) or a code division multiple access (CDMA) system, or a node B (NB) in a wideband code division multiple access (WCDMA) system, or an evolutionary node B (eNB or eNodeB) in a long term evolution (LTE) system, or a wireless controller in a cloud radio access network (CRAN) scenario. Alternatively, the base station can also be a relay station, an access point, an on-board device, a wearable device, a g-node (gNodeB or gNB) in a new radio (NR) system, or a base station in a future evolved network, etc., and the embodiments of the present application are not limited thereto.

[0060] 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 in 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; applicable to single-transmission reception point (Single-TRP) or multiple-transmission reception point (Multi-TRP) scenarios, and any of their derivative scenarios; applicable to new radio access technology (NR) uplink transmission scenarios; applicable to homogeneous networks and heterogeneous networks.

[0061] FIG2 shows a possible structural diagram of a communication system. The base station antenna feeding system may generally include an antenna 100, a mounting bracket 200, an antenna mounting member 300 and other structures. Among them, the base station antenna 100 may include an antenna cover 110. The antenna cover 110 has good electromagnetic wave penetration characteristics in terms of electrical performance and can withstand the influence of harsh external environments in terms of mechanical performance, thereby protecting the antenna 100 from external environmental influences. The antenna 100 can be mounted on the mounting bracket 200 via the antenna mounting member 300 to facilitate the reception or transmission of signals by the antenna 100. Of course, the embodiment shown in FIG2 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 the embodiment shown in FIG2.

[0062] 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 can 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).

[0063] In one possible embodiment, as shown in FIG2 , the RF processing unit 400 may be integrated with the antenna 100, and the baseband processing unit 500 may be located at a remote end of the antenna 100. In other embodiments, the RF processing unit 400 and the baseband processing unit 500 may be located at the remote end of the antenna 100. The RF processing unit 400 and the baseband processing unit 500 may be connected via a cable 600.

[0064] More specifically, reference may be made to Figures 2 and 3 , where Figure 3 is a schematic diagram of the composition of an antenna according to a possible embodiment of the present application. As shown in Figure 3 , the base station antenna 100 may include a radiation unit 120 and a reflector 130. The radiation unit 120 may also be referred to as an antenna vibrator, 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 base plate, an antenna panel, or a reflective surface, etc., and 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 the signal incident on the reflector 130 and transmit it out. The radiation unit 120 is usually placed on one side surface of the reflector 130, which not only greatly enhances the reception or transmission capability of the antenna 100 signal, but also blocks and shields 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 used to set the radiation unit 120) on the antenna signal reception.

[0065] In the base station's antenna 100, the radiating element 120 is connected to a feed network 140. The feed network 140 typically consists of a controlled impedance transmission line. It can feed signals to the radiating element 120 at a specific amplitude and phase, or transmit received signals to the baseband processing unit 500 of the base station at a specific amplitude and phase. Specifically, in some embodiments, the feed network 140 can be used to implement different radiation beam directions or connect to a calibration network to obtain calibration signals required by the system. The feed network 140 may include a phase shifter to change the phase of the antenna signal being radiated. The feed network 140 may also include modules to expand performance, such as a combiner that can combine signals of different frequencies into one channel for transmission through the antenna 100. Alternatively, in reverse, it can be used to split the signals received by the antenna 100 into multiple channels based on frequency for transmission to the baseband processing unit 500 for processing. Alternatively, filters can be used to filter out interference signals.

[0066] It is worth noting that the embodiments involving the word "specific", "specific setting" and "specific design" appearing 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.

[0067] FIG4 is a schematic diagram of the structure of a communication system in the prior art. In the scheme shown in FIG4 , the communication system includes antennas 100 on the periphery of a mounting frame 200. Each antenna 100 is a planar antenna and includes a planar mounting plate. A radiation unit is mounted on the planar mounting plate. The number of radiation units arranged on a certain windward surface is relatively small, and the system capacity gain is relatively small. FIG5 is a schematic diagram of the structure of a communication system in the prior art. As shown in FIG5 , 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. The flag-mounted antenna 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 is a problem of signal shielding between adjacent antennas, resulting in limited gain of the actual communication system. In addition, in this scheme, interference is prone to occur between cells with different signal coverage.

[0068] Figure 6 is a schematic diagram of the structure of a communication system in an embodiment of the present application. As shown in Figure 6, in one embodiment, the communication system provided by the present application includes a mounting frame 200 and at least two antennas 100, and the at least two antennas 100 are mounted on the mounting frame 200 around the circumference of the mounting frame 200. 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, as shown in Figure 6, 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 antenna. Figure 7 is a schematic diagram of the structure of a communication system in an embodiment of the present application. As shown in Figure 7, in one embodiment, the communication system includes three antennas 100, including two V-shaped antennas 1 and a planar antenna. Figure 8 is a schematic diagram of the structure of a communication system in an embodiment of the present application. As shown in Figure 8, in one embodiment, the communication system includes three antennas 100, wherein all three antennas 100 are V-shaped antennas 1.

[0069] When mounting the V-shaped antenna 1 on the mounting bracket 200, an antenna mounting member 300 can be used to connect the V-shaped antenna 1 and the mounting bracket 200. In one embodiment, the antenna mounting member 300 has a Y-shaped structure. Specifically, one end of the antenna mounting member 300 includes two branches, which are connected to the two mounting plates 11 in a one-to-one manner. The other end of the antenna mounting member 300 is connected to the mounting bracket 200, thereby ensuring a relatively stable and reliable installation of the V-shaped antenna 1 on the mounting bracket 200.

[0070] Figure 9 is a structural schematic diagram of a V-shaped antenna in an embodiment of the present application. As shown in Figure 9, in one embodiment, the V-shaped antenna 1 provided in the present application includes two mounting plates 11, and a radiation element array 12 is mounted on the surface of each mounting plate 11 facing away from the mounting frame 200, forming two antenna panels. A radiation element array 12 includes a plurality of radiation elements. The planes on which 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. The above-mentioned first angle β is less than or equal to 150°, that is, β≤150°. Specifically, the V-shaped antenna 1 includes two mounting plates 11 for setting the radiation element array 12, and the two mounting plates 11 form a V-shaped structure, or a substantially V-shaped structure, and the radiation element array 12 is set on the outer surface of the V-shaped structure. There are multiple ways to determine the above-mentioned first angle β. In one determination method, the angle between the planes on which the two mounting plates 11 lie can be used as the first angle β. Alternatively, in one determination method, one of the two mounting plates 11 has a first axis and the other has a second axis, the first and second axes being perpendicular to the centerline of the mounting frame 200 extending along the axis, and the angle between the first and second axes being the first angle β. Alternatively, in another determination method, both mounting plates 11 are rectangular, and at least one set of sides of the two mounting plates 11 is parallel. For example, the long side of one mounting plate 11 is parallel to the long side of the other mounting plate 11 and to the centerline of the mounting frame 200 extending along the axis. The angle between the short side of one mounting plate 11 and the short sides of both mounting plates 11 is the first angle β. When both mounting plates 11 are square, the distinction between long and short sides is not made; the two perpendicular sides of the square mounting plate can be considered to be the long and short sides, 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 .

[0071] The present invention provides a V-shaped antenna 1 in an embodiment. This V-shaped antenna 1 occupies a relatively small area facing the wind and can accommodate a larger number of radiating elements, thereby maximizing the relationship between the windward surface and the radiating area. Referring to FIG8 , adjacent V-shaped antenna 1 brackets are less likely to cause signal obstruction, thereby improving the gain of the communication system.

[0072] In one embodiment, the mounting plate 11 includes a reflector 130. That is, in addition to being used to mount the radiating unit 120, the mounting plate 11 also serves as the reflector 130 to reflect signals from the radiating unit. For example, the mounting plate 11 itself can be made of a metal material, etc., thereby serving as the reflector 130. Alternatively, the reflector 130 can be formed by coating the surface of the mounting plate 11 with a layer of reflective material.

[0073] In a specific embodiment, the first angle β is 60° or 120°. In the embodiment shown in FIG8 , in a typical application scenario, the communication system includes three V-shaped antennas 1 evenly spaced around a mounting frame 200. This minimizes occlusion between adjacent antennas 100, improving the gain of the communication system. This also facilitates coordination between different V-shaped antennas 1 in the communication system to serve different cells.

[0074] 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, thereby making the structure of the V-shaped antenna 1 more regular and facilitating the arrangement of the antenna radiating element array 12, thereby simplifying the control of the antenna 100.

[0075] When mounting the V-shaped antenna 1 on the mounting bracket 200, the positional relationship between the V-shaped antenna 1 and the mounting bracket 200 can be adjusted in a variety of ways, allowing for the placement of the V-shaped antenna 1 based on signal coverage requirements. As shown in Figure 8 , in one application scenario, the two mounting plates 11 of a V-shaped antenna 1 are symmetrical about a first plane, with the axial centerline of the mounting bracket 200 located in the first plane. The two mounting plates 11 of the V-shaped antenna 1 are also symmetrical about the axial centerline of the mounting bracket 200.

[0076] In one embodiment, the multiple V-shaped antennas 1 in the communication system are evenly arranged around the circumference of the mounting bracket 200 , thereby facilitating improvement in the uniformity of the signals of the multiple V-shaped antennas 1 within the coverage area.

[0077] For ease of description, the three V-shaped antennas 1 included in the communication system shown in FIG8 are respectively a first V-shaped antenna 13, a second V-shaped antenna 14, and a third V-shaped antenna 15. The mounting plate 11 of the first V-shaped antenna 13 includes a first mounting plate 131 and a second mounting plate 132. A first radiating element array is mounted on the surface of the first mounting plate 131, and a second radiating element array is mounted on the surface of the second mounting plate 132. The mounting plate 11 of the second V-shaped antenna 14 includes a third mounting plate 141 and a fourth mounting plate 142. A third radiating element array is mounted on the surface of the third mounting plate 141, and a fourth radiating element array is mounted on the surface of the fourth mounting plate 142. The mounting plate 11 of the third V-shaped antenna 15 includes a fifth mounting plate 151 and a sixth mounting plate 152. A fifth radiating element array is mounted on the surface of the fifth mounting plate 151, and a sixth radiating element array is mounted on the surface of the sixth mounting plate 152.

[0078] Figure 10 is a schematic diagram of the structure of a communication system in an embodiment of the present application. As shown in Figure 10, in actual operation, the antenna 100 can have multiple networking configurations. In a typical networking configuration, the signals radiated by the second radiating element array on the second mounting plate 132 and the signals radiated by the third radiating element array on the third mounting plate 141 cover the first cell, i.e., the second radiating element array and the third radiating element array correspond to one cell; the signals radiated by the fourth radiating element array on the fourth mounting plate 142 and the signals radiated by the fifth radiating element array on the fifth mounting plate 151 cover the second cell, i.e., the fourth radiating element array and the fifth radiating element array correspond to one cell; the signals radiated by the sixth radiating element array on the sixth mounting plate 152 and the signals radiated by the first radiating element array on the first mounting plate 131 cover the third cell, i.e., the sixth radiating element array and the first radiating element array correspond to one cell. To achieve the above functions, the second radiating element array and the third radiating element array work in coordination, the fourth radiating element array and the fifth radiating element array work in coordination, and the sixth radiating element array and the first radiating element array work in coordination.

[0079] Specifically, the three V-shaped antennas 1 of the communication system are arranged so that 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 radiating element arrays 12 corresponding to the same cell are adjacent, which facilitates coordination between the two, reduces signal obstruction, and improves signal coverage and strength within the cell.

[0080] Furthermore, the second mounting plate 132 and the third mounting plate 141 are parallel, so that the normal directions of the second and third radiating element arrays are the same, which facilitates improving signal uniformity within the coverage cell and increasing the signal coverage area of ​​the second and third radiating element arrays, or in other words, increasing the area of ​​the first cell. Similarly, the fourth mounting plate 142 and the fifth mounting plate 151 are parallel, so that the normal directions of the fourth and fifth radiating element arrays are the same, which facilitates improving signal uniformity within the coverage cell and increasing the signal coverage area of ​​the fourth and fifth radiating element arrays, or in other words, increasing the area of ​​the second cell. The sixth mounting plate 152 is parallel to the first mounting plate 131, so that the normal directions of the sixth and first radiating element arrays are the same, which facilitates improving signal uniformity within the coverage cell and increasing the signal coverage area of ​​the sixth and first radiating element arrays, or in other words, increasing the area of ​​the third cell.

[0081] In one embodiment, the first angle β of each 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, such that the three cells are equally divided along the circumference, with each cell covering a 120° range. 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 may not be symmetrically positioned relative to the mounting frame 200, thereby enabling targeted enhancement of the signal strength of individual cells.

[0082] Figure 11 is a schematic diagram of the structure of a communication system according to an embodiment of the present application. As shown in Figure 11, in another embodiment, the communication system includes a V-shaped antenna 1 comprising a fourth V-shaped antenna 16 and a fifth V-shaped antenna 17. The mounting plate 11 of the fourth V-shaped antenna 16 comprises a seventh mounting plate 161 and an eighth mounting plate 162. The seventh mounting plate 161 has a seventh radiating element array mounted on its surface, while the eighth mounting plate 162 has an eighth radiating element array mounted on its surface. The mounting plate 11 of the fifth V-shaped antenna 17 comprises a ninth mounting plate 171 and a tenth mounting plate 172. The ninth mounting plate 171 has a ninth radiating element array mounted on its surface, while the tenth mounting plate 172 has a tenth radiating element array mounted on its surface. During operation, the signals radiated by the seventh radiating element array on the seventh mounting plate 161 cover the fourth cell, the signals radiated by the eighth radiating element array on the eighth mounting plate 162 and the ninth radiating element array on the ninth mounting plate 171 cover the fifth cell, and the tenth radiating 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.

[0083] It is worth noting that the communication system may or may not include other antennas in addition to the fourth V-shaped antenna 16 and the fifth V-shaped antenna 17. For example, the communication system may include only 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 include one antenna 100, two antennas 100, or a greater number of antennas 100. Furthermore, the antennas 100 in addition to the fourth V-shaped antenna 16 and the fifth V-shaped antenna 17 may include a V-shaped antenna 1, a flag antenna, or a planar antenna.

[0084] To enable the operation of the V-shaped antenna 1, the V-shaped antenna 1 in the embodiment of the present application further includes a circuit module 18, also referred to as a radio frequency board. This circuit module 18 is connected to the radiating elements of the radiating element array 12, so that signals transmitted or received by the radiating elements are processed and transmitted by the circuit module 18. In one embodiment, the circuit module 18 can be fixed to the mounting plate 11, thereby forming the V-shaped antenna 1 into a module with specific functions. This allows for modularization of the V-shaped antenna 1 and simplifies the process of installing the V-shaped antenna 1 in a communication system.

[0085] Figures 12 to 15 are schematic diagrams of several structures of a V-shaped antenna according to embodiments of the present application. As shown in Figures 12 to 15 , the V-shaped antenna has a V-shaped bracket on the side facing away from the radiating element array. A V-shaped cavity is formed between the V-shaped bracket and the mounting plate, and the circuit module 18 is disposed in the V-shaped cavity. Specifically, there are multiple options for the location of the circuit module 18 in the V-shaped antenna 1. For example, when installing the circuit module 18, the circuit module 18 can be mounted on the side of the two mounting plates 11 facing away from the radiating element array 12, thereby reducing the impact of the circuit module 18 on the radiating element signals. Furthermore, the two mounting plates 11 of the V-shaped antenna 1 have a certain amount of space on the side facing away from the radiating element array 12 for mounting the circuit module 18. As shown in Figures 12 to 14 , in an optional embodiment, the V-shaped antenna 1 can include a circuit module 18, which is connected to each of the two mounting plates 11 and can be connected to different locations on the two mounting plates 11. For example, consider a case where the two mounting plates 11 of a V-shaped antenna 1 have the same width. As shown in FIG12 , in one embodiment, the two ends of the circuit module 18 are respectively connected to the two mounting plates 11, and the connection points of the circuit module 18 and the mounting plates 11 are symmetrically arranged, such as d1=d2 and d3=d4 in FIG12 . As shown in FIG13 , in one embodiment, the two ends of the circuit module 18 are respectively connected to the two mounting plates 11, and the connection points of the two ends of the circuit module 18 and the two mounting plates 11 are respectively in a centrally symmetrical relationship, such as d1=d4 and d2=d3 in FIG13 . As shown in FIG14 , in one embodiment, the two ends of the circuit module 18 are respectively connected to the head and tail of the two mounting plates 11, as shown in FIG14 , one end of the circuit module 18 is connected to the end of one mounting plate 11 away from the other mounting plate 11, and the other end is connected to the end of the other mounting plate 11 toward the one mounting plate 11. Alternatively, as shown in Figure 15, in one embodiment, the above-mentioned V-shaped antenna 1 may also 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.

[0086] Figures 16 to 18 are schematic diagrams of several structures of the V-shaped antenna in the embodiment of the present application. As shown in Figures 16 to 18, the V-shaped antenna has a flat plate bracket on the side away from the radiation unit array. A triangular accommodating cavity is formed between the flat plate bracket and the mounting plate. The circuit module 18 is arranged in the above triangular accommodating cavity. Specifically, the circuit module 18 is fixed to the above flat plate 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, as shown in Figure 16, the two ends of the circuit module 18 are respectively connected to the head and tail of the two mounting plates 11; or as shown in Figure 17, the two ends of the circuit module 18 are respectively connected to the tail of the two mounting plates 11; or, as shown in Figure 18, the two ends of the circuit module 18 are respectively connected to the middle of the two mounting plates 11.

[0087] 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. A signal channel can be connected to one radiation element or to two or more radiation elements.

[0088] FIG19 is a schematic diagram of a radiation element array in an embodiment of the present application. As shown in FIG19 , in one embodiment, the arrangement of the two radiation element arrays 12 radiating signals covering the same cell is the same, and the connection relationship between the radiation elements in the two radiation element arrays 12 and the signal channels is the same. It can be understood that the two radiation element arrays 12 corresponding to the same cell are equivalent to a translation relationship, the arrangement of the radiation elements is the same, and the connection relationship between the radiation elements and the signal channels is also the same. In this solution, SRS channel estimation can be performed separately for the two radiation element arrays 12, which can realize the reuse of hardware resources and help reduce the cost of the V-shaped antenna 1.

[0089] Specifically, as shown in Figure 19, the radiating element array 12 is a 10-column, 24-row matrix, forming a triangular array with 128T DBF. Vertically adjacent crosses of the same color indicate that the radiating elements are connected by a single channel. For convenience, this connection relationship, where one channel corresponds to multiple arrays, is referred to as a drive relationship. If a channel connects 10 arrays, it is called a 1-drive-10 relationship. The radiating element array 12 on a mounting plate 11 shown in the figure has two drive relationships: 1-drive-6 and 1-drive-12. Specifically, the first two and last two columns on the panel each have two channels, while the six columns in the middle each contain four channels.

[0090] FIG20 is a schematic diagram of a radiation element array in an embodiment of the present application. As shown in FIG20 , 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 image relationship. This solution is conducive to 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.

[0091] Specifically, as shown in Figure 20, the radiating element array 12 is a matrix of 11 columns and 24 rows, forming a triangular array with 128T DBF. Vertically adjacent crosses of the same color indicate that the radiating elements are connected by a channel. The radiating element array 12 on a mounting plate 11 shown in the figure has two drive relationships: 1 drive 6 and 1 drive 12.

[0092] FIG21 is a schematic diagram of a radiating element array according to an embodiment of the present application. As shown in FIG21 , in a specific embodiment, two radiating element arrays 12 radiating signals covering the same cell are arranged differently. In one of the two radiating element arrays 12 , every N radiating elements are connected to a signal channel, i.e., a 1-drives-N driving relationship exists. In the other of the two radiating element arrays 12 , some of the multiple radiating elements are connected to a signal channel in a manner such that every M radiating elements are connected to a signal channel, and some of the multiple radiating elements are connected to a signal channel in a manner such that every L radiating elements are connected to a signal channel, with M ≠ L. This means that two driving relationships exist: 1-drives-M and 1-drives-L. Therefore, the driving relationships of the two radiating element arrays 12 corresponding to the same cell can be different.

[0093] Specifically, as shown in FIG21 , 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. Adjacent crosses of the same color in the vertical direction indicate that the radiation elements are connected by a channel. In the figure, the radiation element array 12 on one mounting plate 11 (left side) has a 1-drive-12 drive relationship, while the radiation element array 12 on the other mounting plate 11 (right side) has two drive relationships: 1-drive-6 and 1-drive-12. That is, N=6, M=6, and L=12, and in this embodiment, N=M. In other embodiments, N≠L and N≠M can also be made.

[0094] In a specific embodiment, the two radiation element arrays 12 of the two radiation element arrays 12 whose radiated signals cover the same cell can 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, if O≠P, the driving relationships of the two radiation element arrays 12 are different, which improves the flexibility of signal channel arrangement. In another embodiment, if O=P, the driving relationships of the two radiation element arrays 12 are the same, and the same beam weights can be designed for the two radiation element arrays 12.

[0095] Figure 22 is a schematic diagram of the mechanical downtilt of the V-shaped antenna in an embodiment of the present application. As shown in Figure 22, in one embodiment, in order to improve the performance of the V-shaped antenna 1, in an 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. 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 can be located in the plane where the mounting plate 11 is located, or the above-mentioned mechanical downtilt rotation axis 191 can 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.

[0096] In order to realize the rotation of the mounting plate 11 , the mounting plate 11 may be rotatably mounted relative to the antenna mounting member 300 .

[0097] In other embodiments, the driving mechanism 19 may be connected to only one mounting plate 11 to drive the one mounting plate 11 to rotate around the mechanical downtilt rotation axis 191 to meet specific application requirements of the V-shaped antenna 1 .

[0098] Furthermore, in one embodiment, the drive mechanism 19 includes a first drive mechanism and a second drive mechanism. The first drive mechanism is connected to one mounting plate 11 of the V-shaped antenna 1 and is used to drive the first mounting plate 11 to rotate about its mechanical downtilt axis 191. The second drive mechanism is connected to the other mounting plate 11 of the V-shaped antenna 1 and is used to drive the other mounting plate 11 to rotate about its mechanical downtilt axis 191. In this embodiment, the mechanical downtilt of the two mounting plates 11 of a V-shaped antenna 1 is decoupled. When adjusting the mechanical downtilt of one mounting plate 11, the other mounting plate 11 can either mechanically downtilt or remain stationary, or the two mounting plates 11 can mechanically downtilt at different angles or directions.

[0099] In one 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 .

[0100] In a specific embodiment, the mechanical tilt axis 191 is perpendicular to the centerline of the mounting frame 200 extending along its axis. Therefore, when the mounting plate 11 rotates about the mechanical tilt axis, a fixed positional relationship between the mounting plate 11 and the mounting frame 200 is maintained, and the mounting plate 11 does not deflect along the mechanical tilt axis 191. In one embodiment, the mechanical tilt axis of one mounting plate 11 is parallel to the first axis, while the mechanical tilt axis of the other mounting plate 11 is parallel to the second axis.

[0101] 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 tilt axis 191 is parallel to at least one side of the square mounting plate 11. For example, if the mounting plate 11 is a rectangular mounting plate 11, the long side of one mounting plate 11 is parallel to the long side of the other mounting plate 11 and is parallel to the centerline of the mounting frame 200 extending along the axis. In this case, the mechanical tilt axis 191 is parallel to the short side of the square mounting plate 11. Alternatively, the mechanical tilt axis 191 is parallel to the top or bottom side of the square mounting plate 11.

[0102] In specific applications, the driving mechanism 19 drives the radiated signal to cover the same cell, maintaining the mounting plates 11 of the two radiating element arrays 12 parallel to each other. This solution maintains a certain degree of signal uniformity within a cell and provides a larger coverage area. Furthermore, based on actual needs, the driving mechanism 19 can also be configured to maintain a certain angle between the mounting plates 11 of the two radiating element arrays 12 in the same cell, thereby specifically improving signal coverage strength in certain areas.

[0103] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
