[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 March 30, 2024, with application number 202410396237.X and application name "A Radome Assembly, Antenna and Base Station", 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 radome assembly, an antenna, and a base station. Background Art

[0004] With the development of mobile communication technology, the usage rate of mobile terminals is increasing. The network coverage of mobile cellular networks is crucial for mobile communications. A key component in mobile cellular networks is the antenna. Generally, the antenna's gain is positively correlated with its physical size. In other words, a larger antenna is required for higher antenna gain.

[0005] Base station antennas are typically mounted on masts high up on towers or buildings. The larger the antenna, the greater the wind load it bears. This wind load directly impacts the antenna's mounting reliability on the mast and the pressure it can withstand on the mast and tower. Large-diameter antennas, in particular, may be unable to be mounted on a tower due to the tower's limited load-bearing capacity. Therefore, ensuring that the antenna's size meets performance requirements while improving its mounting reliability on the mast has become a pressing challenge for those skilled in the art. Summary of the Invention

[0006] The present application provides a radome assembly, an antenna, and a base station to improve the installation reliability of the radome assembly in the base station, thereby improving the structural reliability of the base station.

[0007] In a first aspect, the present application provides a radome assembly that can be mounted on a pole. The radome assembly includes a first radome and a second radome. The first and second radomes are detachably connected. When connected, the first and second radomes contain a mounting cavity. The height of the first and second radomes is defined as a first direction. The mounting cavity extends along the first direction and can accommodate a pole. In other words, when the radome assembly is mounted on a pole, the pole can be inserted into the mounting cavity. This design allows the radome assembly and the pole to form an integrated design. The wind loads experienced by the combined radome assembly and the pole are comparable to those of the radome assembly itself. This reduces lateral impacts on the pole caused by wind loads when the radome assembly is placed sideways on the pole, allowing the radome assembly to be more stably fixed to the pole, thereby improving the structural reliability of the base station.

[0008] In some embodiments, the first antenna cover is connected to the pole, and the second antenna cover is connected to the first antenna cover. There may be no connection between the second antenna cover and the pole. This allows the antenna cover assembly to be installed on the pole without increasing the difficulty of installation.

[0009] In some embodiments, the first antenna cover and the second antenna cover can be connected to form an installation cavity. This design can simplify the structural design of the first antenna cover or the second antenna cover to a certain extent, thereby helping to reduce the overall weight of the antenna cover assembly.

[0010] In some embodiments, the first antenna cover may include a first cover body, and the second antenna cover may include a second cover body. The first cover body and the second cover body each extend along a first direction, and the projection of the first cover body in the first direction includes a first arc segment, and the projection of the second cover body in the first direction includes a second arc segment. By designing the first and second covers in this manner, the contact area between the first and second covers and the air can be reduced, thereby reducing the wind load on the first and second covers.

[0011] In some embodiments, the first antenna cover can be used to install components such as the antenna's radiation unit and feeding network. The first antenna cover can include two end covers, which can be respectively arranged at the two ends of the first cover body along the first direction, and each end cover blocks one end of the first cover body, so that the first antenna cover forms a closed cavity, so that the first antenna cover can provide dust-proof, waterproof and other protection for the components accommodated in its cavity.

[0012] In some embodiments, the projection of the first cover in the first direction includes a first arc segment and a straight segment, with the ends of the first arc segment connected to the ends of the straight segment. The projection of the second cover in the first direction is a second arc segment, with the ends of the second arc segment connected to the ends of the straight segment. Thus, the shape enclosed by the second arc segment and the straight segment is the projection of the installation cavity in the first direction, thereby achieving a design in which the second cover and the first cover enclose a mounting cavity.

[0013] In some embodiments, the radius of the first arc segment is approximately equal to the radius of the second arc segment, and the center of the first arc segment and the center of the second arc segment are at the same point, so that the first arc segment and the second arc segment can form an approximate circle, which helps to further reduce the wind load of the antenna and improve the installation reliability of the antenna on the pole.

[0014] In some embodiments, the projection of the first cover in the first direction includes a first arc segment, a first straight segment, a second straight segment, and a third straight segment. The two ends of the first straight segment are respectively connected to one end of the first arc segment and one end of the third straight segment, and the two ends of the second straight segment are respectively connected to the other end of the first arc segment and the other end of the third straight segment, so that the projection of the first cover in the first direction forms a shape that is approximately half a runway. The projection of the second cover in the first direction includes a second arc segment, a fourth straight segment, and a fifth straight segment. The two ends of the fourth straight segment are respectively connected to one end of the second arc segment and one end of the third straight wall, and the two ends of the fifth straight segment are respectively connected to the other end of the second arc segment and the other end of the third straight wall. Therefore, the second arc segment, the fourth straight segment, the fifth straight segment, and the third straight segment can also form a shape that is approximately half a runway. In this way, the shape enclosed by the second arc segment, the fourth straight segment, the fifth straight segment, and the third straight segment is the projection of the installation cavity in the first direction, thereby realizing a design in which the second cover and the first cover enclose a mounting cavity. This design can not only reduce the wind load on the radome assembly to a certain extent, but also enable the first radome and the second radome to have a relatively large internal space.

[0015] In some embodiments, the diameter of the first arc segment is approximately equal to the diameter of the second arc segment, and the distance between the vertex of the first arc segment and the vertex of the second arc segment can be greater than or equal to the diameter of the first arc segment. The first antenna cover and the second antenna cover that meet this size design have better space utilization, which helps to further improve the radiation performance of the antenna.

[0016] In some embodiments, the second antenna cover further includes two fixing bars, which extend respectively along the first direction and are spaced apart on the side of the second cover body facing the first cover body. The second cover body can be connected to the first cover body through the two fixing bars to improve the connection reliability between the second cover body and the first cover body.

[0017] For example, the fixing strip can be connected to the first cover body by a snap-fitting manner. Alternatively, the fixing strip can be connected to the first cover body by a fastener.

[0018] In some embodiments, the first antenna cover and the second antenna cover can be one each, and the top of the first antenna cover is coplanar with the top of the second antenna cover, and the bottom of the first antenna cover is coplanar with the bottom of the second antenna cover. This can improve the wrapping of the antenna cover assembly on the pole, thereby helping to further improve the structural stability of the pole and the base station as a whole.

[0019] In some embodiments, there is a single first antenna cover and multiple second antenna covers, arranged along the first direction, with intervals between adjacent second antenna covers. In this case, each second antenna cover and the first antenna cover, when connected, contain a mounting cavity. The multiple mounting cavities are spaced apart along the first direction, and the mast is sequentially positioned within the multiple mounting cavities.

[0020] In some embodiments, among the multiple second antenna covers arranged along the first direction, the top of one second antenna cover is coplanar with the top of the first antenna cover, and the bottom of another second antenna cover is coplanar with the bottom of the first antenna cover. In this way, except for the gaps between adjacent second antenna covers, other positions of the antenna can wrap the pole, thereby improving the structural stability of the pole and the base station as a whole.

[0021] In some embodiments, the first radome is made of, but not limited to, thermosetting or thermoplastic materials such as fiberglass, polyvinyl chloride, or a copolymer of styrene, acrylonitrile, and acrylic rubber. This ensures that the first radome has sufficient structural strength while still achieving cell wave penetration. Similarly, the second radome is made of, but not limited to, thermosetting or thermoplastic materials such as fiberglass, polyvinyl chloride, or a copolymer of styrene, acrylonitrile, and acrylic rubber.

[0022] In a second aspect, the present application further provides an antenna comprising a radiating unit, a feed network, and a radome assembly according to any possible implementation scheme of the first aspect, wherein the radiating unit and the feed network are disposed within at least one of the first radome and the second radome, and the radiating unit is connected to the feed network. In the present application, the radome assembly and the pole can form an integrated fusion design, and the wind load on the structure after the radome assembly and the pole are combined is equivalent to the wind load on the radome assembly itself. Therefore, when the radome assembly is placed sideways on the pole, the lateral impact of the radome assembly on the pole when subjected to wind load can be avoided, so that the radome assembly can be more stably fixed to the pole, thereby improving the structural reliability of the base station.

[0023] In the third aspect, the present application also provides a base station, which includes a holding pole and the antenna provided in the second aspect above. The first antenna cover is connected to the holding pole, and the holding pole is arranged in the installation cavity formed by the first antenna cover and the second antenna cover, thereby forming an integrated fusion design with the antenna cover assembly, so that the antenna cover assembly can be more stably fixed to the holding pole, thereby improving the structural reliability of the base station.

[0024] In some embodiments, the base station also includes a mounting member, and the first radome can be secured to the pole via the mounting member. This allows the mounting member to remain within the mounting cavity even after the entire antenna is mounted on the pole, more reliably connecting the antenna to the pole. Furthermore, since the antenna is fully supported by the mounting member, placing the mounting member between the first and second radomes brings the antenna's center of gravity closer to the mounting member, improving the force applied to the mounting member and enhancing its reliability.

[0025] In a fourth aspect, the present application further provides a communication system, comprising the base station of the third aspect. Furthermore, the communication system may further include a terminal, wherein the base station and the terminal are communicatively connected so that the terminal can transmit and receive signals through the base station. The communication system provided by the present application has high reliability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all explained using the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings in the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0047] It should be noted that the following description sets forth specific details to facilitate understanding of the present application. However, the embodiments of the present application can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotations of the embodiments of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0048] Figure 1 exemplarily shows a schematic diagram of a system architecture applicable to an embodiment of the present application. As shown in Figure 1, the system architecture includes a wireless access network communication device and a terminal, and wireless communication can be carried out between the communication device and the terminal. The embodiment shown in Figure 1 is explained by taking the communication device as a base station as an example. 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 connection between the terminal device and the wireless network radio frequency end.

[0049] Specifically, a 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, a node B (NB) in a wideband code division multiple access (WCDMA) system, an evolutionary node B (eNB or eNodeB) in a long term evolution (LTE) system, a transmission reception point (TRP), a next generation node B (gNB) in a 5G mobile communication system, an access network device or a module of an access network device in a future communication network or open access network (ORAN) system, a base station in a future mobile communication system, or an access node in a WiFi system. A base station can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). In the ORAN system, CU can also be called O-CU, DU can also be called open (O)-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CUP-UP, and RU can also be called O-RU. A base station can communicate with a terminal or communicate with the terminal through a relay station. A terminal can communicate with multiple base stations using different access technologies.

[0050] Figure 2 illustrates an installation scenario for a base station 1000 according to an embodiment of the present application. Referring to Figure 2 , in this embodiment, base station 1000 includes a mast 100 and an antenna 200. Antenna 200 is used to receive or transmit electromagnetic waves and is mounted on mast 100, which is in turn secured to a mounting surface. For example, this mounting surface can be a structural plane high up in a building, such as a rooftop, to meet the required radiation distance for antenna 200 and increase the base station's coverage area.

[0051] In one implementation, the base station 1000 further includes a mounting member 300, through which the antenna 200 can be detachably mounted on the mast 100, thereby improving the installation convenience of the antenna 200. Furthermore, the base station 1000 may further include a support rod 400, one end of which is connected to the mast 100 and the other end of which is fixed to the mounting surface. The support rod 400 is arranged at an angle relative to the mast 100, and the angle between the support rod 400 and the mast 100 is acute. The support rod 400 supports the mast 100, thereby improving the structural stability of the mast 100 and reducing the risk of the mast 100 toppling due to external forces. For example, there may be multiple support rods 400, which may be spaced circumferentially around the mast 100 to further improve the support reliability of the mast 100.

[0052] FIG3 is another installation scenario diagram of a base station 1000 provided in an embodiment of the present application. Referring to FIG3 , in an embodiment of the present application, the base station 1000 also includes a pole 100 and an antenna 200. Unlike the aforementioned embodiment, the base station in this embodiment further includes a support structure 500. The support structure 500 can be an antenna pole or an antenna tower. This application does not limit this. FIG3 uses an antenna pole as an example for illustration. The pole 100 is installed at a high point of the support structure 500, and the support structure 500 is fixed to the installation surface. When the support structure is an antenna pole, the installation surface can be either the ground or a structural plane at a high point of a building. In actual applications, an antenna pole of appropriate height can be selected according to the specific installation location of the base station 1000. When the support structure 500 is an antenna tower, the installation surface is usually the ground.

[0053] In this embodiment, the base station may include multiple antennas 200 and multiple poles 100. The multiple antennas 200 are mounted on the multiple poles 100 in a one-to-one correspondence. The multiple poles 100 may be arranged around the perimeter of the support structure 500. In this way, the base station 1000 can radiate electromagnetic waves in all directions or receive electromagnetic waves from all directions through the multiple antennas 200 arranged around the perimeter, thereby improving the communication capabilities of the base station 1000.

[0054] In one implementation, the base station 1000 further includes a crossbar 600, which can be arranged substantially horizontally. One end of the crossbar 600 is fixedly connected to the support structure, and the other end of the crossbar 600 is fixedly connected to the mast 100, so that the mast 100 can be secured to the support structure 500 via the crossbar 600. Furthermore, the support structure 500 can further include a mounting platform 510, which is arranged in a ring-shaped manner around the main body of the support structure 500. One end of the crossbar 600 can be connected to the mounting platform 510. If there are multiple antennas 200, the mounting platform 510 can provide sufficient installation space for multiple antennas 200, while also improving the reliability of the connection between the antennas 200 and the support structure 500. Furthermore, if the support structure 500 is an antenna tower, the mounting platform 510 can also provide standing space for operators during installation or adjustment of the antennas 200, thereby improving operational convenience.

[0055] Each mast 100 can be secured to the support structure 500 via a single crossbar 600, or via multiple crossbars 600. This is not a limitation of the present application and can be designed based on the size and weight of the antenna 200 mounted on the mast 100. For example, FIG3 illustrates a scenario in which the mast 100 is secured via two crossbars 600. In the example shown in FIG3 , along the length of the mast 100, the connection between one crossbar 600 and the mast 100 is within the overlapping length range of the mast 100 and the antenna 200, while the connection between the other crossbar 600 and the mast 100 is outside the overlapping region. Alternatively, a plane perpendicular to the crossbar 600 is defined as a reference plane, with the projection of one crossbar 600 on the reference plane within the projection of the antenna 200 on the reference plane, and the projection of the other crossbar 600 on the reference plane outside the projection of the antenna 200 on the reference plane. This mounting method is suitable for relatively short antennas 200.

[0056] Figure 4 is an installation scenario diagram of another base station provided in an embodiment of the present application. Referring to Figure 4, in an embodiment of the present application, the base station is also in the form of a supporting structure 500 such as an antenna 200 pole or an antenna 200 tower, and the holding pole 100 is fixedly connected to the supporting structure through one or more cross bars 600. Figure 4 shows another situation in which the holding pole 100 is fixed by two cross bars 600. Unlike the aforementioned embodiment, in this embodiment, the connection positions of the two cross bars 600 and the holding pole 100 are both within the length range of the overlapping of the holding pole 100 and the antenna 200, that is, the projections of the two holding poles 100 on the reference plane are both within the projection range of the antenna 200 on the reference plane, and the reference plane here is also a plane perpendicular to the cross bars 600. This installation method can be applied to situations where the height of the antenna 200 is relatively high.

[0057] Currently, with the development of mobile communication technology, the coverage range of base stations 1000 continues to increase, which places higher requirements on the diameter of antenna 200. A larger diameter of antenna 200 means a larger structural size of antenna 200. As can be seen from the above description of base stations, antenna 200 is installed high up on a building or support structure 500 via a mast 100. The larger the size of antenna 200, the more likely it is to be subjected to excessive wind loads, which in turn can lead to reliability issues with the antenna 200's installation on the mast 100 and excessive wind loads on the mast 100 itself.

[0058] In view of this, an embodiment of the present application provides an antenna 200 that can be mounted around the perimeter of a mast 100, achieving an integrated design with the mast 100. Therefore, the wind load on the combined structure of the antenna 200 and the mast 100 is equivalent to the wind load on the antenna 200 itself. This allows the antenna 200 to meet dimensional design requirements while improving the installation stability of the antenna 200 on the mast 100 and the structural reliability of the mast 100 itself. The antenna 200 provided in this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] Figure 5 is a schematic diagram of the assembled structure of an antenna 200 and a mast 100 according to an embodiment of the present application, and Figure 6 is a partially exploded schematic diagram of the antenna 200 and mast 100 shown in Figure 5 . Referring to Figures 5 and 6 , in an embodiment of the present application, the antenna 200 may include a radome assembly, a radiating element 230, and a feed network (not shown). The radome assembly may include a first radome 210 and a second radome 220. The radiating element 230 and the feed network may be disposed within at least one of the first radome 210 and the second radome 220, and the radiating element 230 is connected to the feed network. Figures 5 and 6 illustrate an example in which the radiating element 230 and the feed network are disposed within the first radome 210, while the second radome 220 is not. Of course, in some other implementations, the second antenna cover 220 may be provided with a radiation unit 230 and a feeding network, and the first antenna cover 210 may not be provided with a radiation unit 230 and a feeding network, or the first antenna cover 210 and the second antenna cover 220 may be provided with a radiation unit 230 and a feeding network respectively.

[0060] The first antenna cover may be made of, but not limited to, thermosetting or thermoplastic materials such as fiberglass, polyvinyl chloride (PVC), or a plastic copolymerized from styrene, acrylonitrile, and acrylic rubber (ASA plastic). This ensures that the first antenna cover has sufficient structural strength while ensuring cell wave penetration. Similarly, the second antenna cover may be made of, but not limited to, thermosetting or thermoplastic materials such as fiberglass, PVC, or ASA plastic.

[0061] Radiating element 230, also known as an antenna element or vibrator, effectively radiates or receives antenna signals. Antenna 200 may include multiple radiating elements 230 arranged in an array, thereby forming one or more antenna arrays to enhance the directivity of the radiation field of antenna 200. For example, in this embodiment, multiple radiating elements 230 form three antenna arrays, each of which includes several radiating elements 230. Antenna 200 may also include a reflector 240, located within the antenna housing where radiating elements 230 are located. Reflector 240 may also be referred to as a base plate, antenna panel, or reflective surface. Reflector 240 can reflect and focus received signals at the receiving point. The radiation unit 230 is usually placed on one side of the reflector 240, which not only enhances the reception or transmission capability of the antenna 200 signal, but also blocks and shields the interference of other radio waves from the back side of the reflector 240 (the back side of the reflector 240 in this embodiment refers to the side opposite to the reflector 240 used to set the radiation unit 230) on the reception of the antenna 200 signal.

[0062] The feed network can feed signals sent by the base station's RF processing unit to the radiating unit at a specific amplitude and phase, or can transmit wireless signals received by the radiating unit to the base station's RF processing unit at a specific amplitude and phase. The feed network can include at least one of a phase shifter, a combiner, a transmission or calibration network, or a filter. This application does not limit the components, types, or functions of the feed network.

[0063] It is worth mentioning that when radiation units 230 are provided in both the first antenna cover 210 and the second antenna cover 220, the operating frequency band of the radiation unit 230 in the first antenna cover 210 and the operating frequency band of the radiation unit 230 in the second antenna cover 220 may be the same or different, and this application does not limit this.

[0064] Continuing with Figures 5 and 6 , in this embodiment of the present application, the first antenna cover 210 and the second antenna cover 220 are detachably connected. When connected, the first and second antenna covers 210, 220 contain a mounting cavity 250. The height of the first and second antenna covers 210, 220 is defined as a first direction. The mounting cavity 250 extends along the first direction and can accommodate the pole 100. In other words, when the antenna 200 is mounted on the pole 100, the pole 100 can be inserted into the mounting cavity 250. Through this design, the antenna 200 and the pole 100 can form an integrated fusion design. The wind load on the structure after the antenna 200 and the pole 100 are combined is equivalent to the wind load on the antenna 200 itself. Therefore, when the antenna 200 is placed sideways on the pole 100, the lateral impact on the pole 100 caused by the wind load on the antenna 200 can be avoided. The antenna 200 can be fixed to the pole 100 more stably, which provides feasibility for the reliable installation of large-diameter antennas 200 in base stations.

[0065] In one embodiment, there is one first radome 210 and one second radome 220. The first radome 210 and the second radome 220 are of the same height, and the top of the first radome 210 is coplanar with the top of the second radome 220, and the bottom of the first radome 210 is coplanar with the bottom of the second radome 220. This prevents a situation where a radome is located on one side of the pole 100 but not on the other side, thereby improving the antenna 200's wrapping around the pole 100 and further helping to enhance the overall structural stability of the pole 100 and the base station. This design of antenna 200 can be used in base stations where the pole 100 is directly fixed to a mounting surface, such as the base station shown in Figure 2.

[0066] When mounting the antenna 200 on the mast 100, the first radome 210 can be first secured to the mast 100, and then the second radome 220 can be secured to the first radome 210, so that the mast 100 is enclosed within the mounting cavity 250 formed by the first and second radomes 210, 220. For example, the first radome 210 can be secured to the mast 100 via a mounting member 300. This allows the mounting member 300 to remain within the mounting cavity 250 after the antenna 200 is fully mounted on the mast 100, thus more reliably connecting the antenna 200 to the mast 100. Furthermore, since the antenna 200 is fully supported by the mounting member 300, placing the mounting member 300 between the first and second radomes 210, 220 brings the center of gravity of the antenna 200 closer to the mounting member 300, thereby improving the stress on the mounting member 300 and enhancing its reliability.

[0067] Figure 7 is a top view of the antenna 200 and mast 100 shown in Figure 5 , and Figure 8 is a top view of the antenna 200 and mast 100 shown in Figure 6 . Referring to Figures 7 and 8 , in this embodiment of the present application, the first antenna cover 210 and the second antenna cover 220, when connected, can enclose a mounting cavity 250 . The first antenna cover 210 can include a first cover 211, and the second antenna cover 220 can include a second cover 221. The first cover 211 and the second cover 221 can each extend along a first direction (see Figure 5 ). The first cover 211 can be a circumferentially closed structure, meaning that its projection in the first direction forms a closed shape. The outer wall of the first cover 211 is fixedly connected to the mast 100 via a mounting member 300 . The second cover 221 can be a circumferentially open structure, meaning that its projection in the first direction forms an open shape. The opening of the second cover 221 is disposed toward the first cover 211 and can be blocked by a portion of the first cover 211. Thus, the second cover 221 and a portion of the first cover 211 enclose the installation cavity 250.

[0068] In addition, referring to Figure 6 , when a radiating element 230 is disposed within the first radome 210, the first radome 210 may further include two end caps 212. These end caps 212 may be disposed at the two ends of the first housing 211 along the first direction, with each end cap 212 sealing one end of the first housing 211. This allows the first radome 210 to form a closed cavity, enabling the first radome 210 to provide dustproof and waterproof protection for the components housed therein. When a radiating element 230 is not disposed within the second radome 220, the second radome 220 may or may not include end caps, as this is not specifically limited in this application. That is, for either the first radome 210 or the second radome 220, when a radiating element 230 is disposed within the radome, the two end caps seal the ends of the radome to form a closed cavity. When a radiating element 230 is not disposed within the radome, the end caps may or may not be present.

[0069] In the embodiment of the present application, the projection of the first cover 211 in the first direction may include a first curved segment 2111, and the projection of the second cover 221 in the first direction may include a second curved segment 2211. In other words, the outer wall of the first cover 211 and the second cover 221 each include a curved wall. Compared to a planar outer wall structure, the curved walls of the first and second covers 211, 221 can reduce their contact area with air, effectively reducing air resistance. This can reduce wind loads on the first and second covers 211, 221, and thus reduce wind loads on the combined structure of the antenna 200 and the mast 100, thereby improving the structural reliability of the base station.

[0070] In this embodiment, the first housing 211 can be approximately semi-cylindrical. In addition to the curved wall, the first housing 211 also includes a straight wall. The curved wall 211a of the first housing 211 projects in the first direction as the aforementioned first curved segment 2111. The straight wall 211b of the first housing 211 projects in the first direction as a straight segment 2112. The two ends of the first curved segment 2111 are connected to the two ends of the straight segment 2112, respectively, so that the projection of the first housing 211 in the first direction forms an approximately semi-circular shape. The straight wall 211b of the first housing 211 is positioned toward the second housing 221 and serves as the outer wall connecting the first radome 210 to the mounting member 300. The second cover 221 is connected to the straight wall 211b of the first cover 211. The projection of the curved wall 221a of the second cover 221 in the first direction forms a second curved segment 2211. The two ends of the second curved segment 2211 are respectively connected to the two ends of the straight segment 2112. Therefore, the second curved segment 2211 and the straight segment 2112 can also form a shape that is approximately semicircular. It is easy to understand that the shape enclosed by the second curved segment 2211 and the straight segment 2112 is the projection of the installation cavity 250 in the first direction.

[0071] In a specific implementation, the radius of the first arc segment 2111 is approximately equal to the radius of the second arc segment 2211, and the center of the first arc segment 2111 and the center of the second arc segment 2211 are at the same point, so that the first arc segment 2111 and the second arc segment 2211 can form an approximate circle, that is, the arc wall 211a of the first cover body 211 and the arc wall 221a of the second cover body 221 can be connected to form the outer wall of a cylinder, so the outer wall of the entire circumference of the antenna 200 is an arc structure, which helps to further reduce the wind load of the antenna 200 and improve the installation reliability of the antenna 200 on the pole 100. In addition, in combination with Figures 5 and 6, it can be seen that the first cover body 211 is completely located on one side of the holding pole 100, and the second cover body 221 extends from the other side of the holding pole 100 to the side where the first cover body 211 is located. Therefore, in the specific design, the central angle of the first arc segment 2111 can be smaller than the central angle of the second arc segment 2211.

[0072] Continuing with reference to Figures 7 and 8, in the embodiment of the present application, the second antenna cover 220 may include fixing bars 222, each extending along a first direction. The fixing bars 222 are connected to a side of the second cover 221 facing the first cover 211. The second cover 221 may be detachably connected to the first cover 211 via the fixing bars 222. There may be two fixing bars 222, and utilizing two fixing bars 222 can increase the connection positions between the second cover 221 and the first cover 211, thereby improving the reliability of the connection between the second cover 221 and the first cover 211. For example, the two fixing bars 222 may be connected to the two ends of the curved wall 221a of the second cover 221, and the two fixing bars 222 may be connected to the straight wall 211b of the first cover 211.

[0073] In one implementation, the fixing bar 222 can be connected to the first cover body 211 by snapping. For example, the fixing bar 222 is provided with a hook, and the straight wall 211b of the first cover body 211 is provided with a hole, or the fixing bar 222 is provided with a hole, and the straight wall 211b of the first cover body 211 is provided with a hook. In this way, the second cover body 221 can be fixed to the first cover body 211 through the cooperation of the hook and the hole.

[0074] In another embodiment, the fixing bar 222 can be connected to the first cover 211 via fasteners. In a specific embodiment, the fixing bar 222 and the straight wall 211b of the first cover 211 are respectively provided with mounting holes. The fasteners are sequentially inserted through the mounting holes of the fixing bar 222 and the mounting holes of the straight wall 211b of the first cover 211, and are locked at the ends of the fasteners via nuts.

[0075] Figure 9 is a top view of the alternative antenna 200 and the mast 100 shown in Figure 5 , and Figure 10 is a top view of the alternative antenna 200 and the mast 100 shown in Figure 6 . Referring to Figures 9 and 10 , in the embodiment of the present application, both the first cover 211 and the second cover 221 can be circumferentially closed structures. The structure of the first cover 211 can be designed with reference to the embodiments shown in Figures 7 and 8 , and will not be repeated here. In addition to the curved wall, the second cover 221 may also include an extension wall 221d. The curved wall 221a of the second cover 221 projects in the first direction as the second curved segment 2211. The extension wall 221d of the second cover 221 projects in the first direction as an extension segment 2214. The ends of the extension segment 2214 are respectively connected to two points of the second curved segment 2211 other than the two endpoints, thereby connecting the second curved segment 2211 and the extension segment 2214 to form a closed shape. In this case, the second housing 221 may also include two end caps, one disposed at each end of the second housing 221 along the first direction. Each end cap can block the space enclosed by the curved wall 221a of the second housing 221 and the extended wall 221d of the second housing 221, thereby forming the second antenna housing 220 into a closed cavity. With this design, the second antenna housing 220 may also be provided with a radiating element 230 and a feed network. The extension section 2214 may be a straight segment, an arc segment, or a curved segment, which is not limited in this application. Figures 9 and 10 illustrate this by taking the extension section 2214 as a curved segment as an example.

[0076] In addition, the two ends of the second arc segment 2211 can be respectively connected to the two ends of the straight segment 2112, so that the second arc segment 2211, the extension segment 2214 and the straight segment 2112 can enclose and form a closed figure. It is easy to understand that the closed figure is the projection of the installation cavity 250 in the first direction. In this embodiment, the second cover body 221 can also be detachably connected to the first cover body 211 via two fixing bars 222. The two fixing bars 222 can be respectively arranged on the side of the second cover body facing the first cover body 211, and the two fixing bars 222 are respectively detachably connected to the first cover body 211. For example, the fixing bars 222 and the first cover body 211 can be snap-fitted or connected by fasteners. The specific connection method can be referred to the description in the previous embodiment and will not be repeated here.

[0077] Figure 11 is a top view of the alternative antenna 200 and the mast 100 shown in Figure 5 , and Figure 12 is a top view of the alternative antenna 200 and the mast 100 shown in Figure 6 . Referring to Figures 11 and 12 , in the embodiment of the present application, the first cover 211 may also be a circumferentially closed structure. In addition to the curved wall, the first cover 211 also includes three straight walls, namely a first straight wall 211c, a second straight wall 211d, and a third straight wall 211e. The first straight wall 211c and the second straight wall 211d are respectively connected between the curved wall 211a and the third straight wall 211e of the first cover 211, and the first straight wall 211c and the second straight wall 211d are substantially parallel. The curved wall 211a of the first cover 211 projects in the first direction as a first curved segment 2111. The first straight wall 211c projects in the first direction as a first straight segment 2113. The second straight wall 211d projects in the first direction as a second straight segment 2114. The third straight wall 211e projects in the first direction as a third straight segment 2115. The first straight segment 2113's two ends connect to one end of the first curved segment 2111 and one end of the third straight segment 2115, respectively. The second straight segment 2114's two ends connect to the other end of the first curved segment 2111 and the other end of the third straight segment 2115, respectively. As a result, the projection of the first cover 211 in the first direction forms a shape similar to half a runway. The third straight wall 211e faces the second cover 221 and serves as the outer wall connecting the first radome 210 to the mounting member 300.

[0078] The second cover 221 is a structure with an opening in its circumference. The second cover 221 is connected to the third straight wall 211e of the first cover 211. In addition to the curved wall, the second cover 221 also includes two straight walls: a fourth straight wall 221b and a fifth straight wall 221c. The fourth and fifth straight walls 221b and 221c are respectively connected to the curved wall 221a of the second cover 221 and are substantially parallel to each other. The curved wall 221a of the second cover 221 is projected in the first direction as a second curved segment 2211. The fourth and fifth straight walls 221b are projected in the first direction as a fourth straight segment 2212. The fifth straight wall 221c is projected in the first direction as a fifth straight segment 2213. The ends of the fourth straight segment 2212 are connected to one end of the second curved segment 2211 and one end of the third straight wall 211e, respectively. The ends of the fifth straight segment 2213 are connected to the other end of the second curved segment 2211 and the other end of the third straight wall 211e, respectively. Therefore, the second curved segment 2211, the fourth straight segment 2212, the fifth straight segment 2213, and the third straight segment 2115 can also form a shape that approximates half a runway. It is easy to understand that the shape enclosed by the second curved segment 2211, the fourth straight segment 2212, the fifth straight segment 2213, and the third straight segment 2115 is the projection of the mounting cavity 250 in the first direction.

[0079] In a specific implementation, the radius of the first arc segment 2111 is approximately equal to the radius of the second arc segment 2211, the first straight segment 2113 is collinear with the fourth straight segment 2212, and the second straight segment 2114 is collinear with the fifth straight segment 2213. Thus, the first arc segment 2111, the first straight segment 2113, the fourth straight segment 2212, the second arc segment 2211, the fifth straight segment 2213, and the second straight segment 2114 form a shape that approximates a runway. This design not only reduces the wind load on the antenna 200 to a certain extent, but also allows the first radome 210 and the second radome 220 to have a relatively large internal space. If radiating elements 230 are disposed within the radomes, the number of radiating elements 230 can be increased, thereby enabling the radiating elements 230 to form more antenna arrays, or increasing the number of radiating elements 230 in each antenna array, thereby improving the radiation performance of the antenna 200.

[0080] For example, in this embodiment, the distance H between the vertex of the first arc segment 2111 and the vertex of the second arc segment 2211 can be greater than or equal to the diameter of the first arc segment. The space utilization rate of the first antenna cover and the second antenna cover that meet this size design is better, which helps to further improve the radiation performance of the antenna 200.

[0081] In addition, in the embodiment of the present application, the second cover 221 can also be detachably connected to the first cover 211 via two fixing bars 222. The two fixing bars 222 can be respectively disposed at one end of the fourth straight wall 221b and the fifth straight wall 221c away from the curved wall of the second cover 221. The two fixing bars 222 are respectively connected to the third straight wall 211e of the first cover 211. For example, the fixing bars 222 and the first cover 211 can be connected by snapping or by fasteners. The specific connection method can be referred to the description of the previous embodiment and will not be repeated here.

[0082] Figure 13 is a top view of the alternative antenna 200 and the mast 100 shown in Figure 5 , and Figure 14 is a top view of the alternative antenna 200 and the mast 100 shown in Figure 6 . Referring to Figures 13 and 14 , in the embodiment of the present application, the first cover 211 and the second cover 221 are each a circumferentially closed structure. The structure of the first cover 211 can be designed with reference to the embodiments shown in Figures 11 and 12 , and will not be repeated here. In addition to the arcuate wall, the fourth straight wall 221b and the fifth straight wall 221c, the second cover body 221 also includes an extension wall 221d. The projection of the arcuate wall 221a of the second cover body 221 in the first direction is the second arcuate segment 2211, the projection of the fourth straight wall 221b in the first direction is the fourth straight segment 2212, the projection of the fifth straight wall 221c in the first direction is the fifth straight segment 2213, and the projection of the extension wall 221d in the first direction is the extension segment 2214. One end of the extension segment 2214 is connected to another point of the fourth straight segment 2212 other than the two endpoints, and the other end of the extension segment 2214 is connected to another point of the fifth straight segment 2213 other than the two endpoints, so that the second arcuate segment 2211, the fourth straight segment 2212, the fifth straight segment 2213 and the extension segment 2214 are connected to form a closed figure. In this case, the second housing 221 may also include two end caps, one disposed at each end of the second housing 221 along the first direction. Each end cap can block the space enclosed by the curved wall 221a, the fourth straight wall 221b, the fifth straight wall 221c, and the extension wall of the second housing 221, thereby forming the second antenna housing 220 into a closed cavity. With this design, the second antenna housing 220 may also be provided with a radiating element 230 and a feed network. The extension section 2214 may be a straight segment, an arcuate segment, or a curved segment, which is not limited in this application. Figures 13 and 14 illustrate the curved extension section 2214 as an example.

[0083] In addition, the end of the fourth straight segment 2212 away from the second curved segment 2211 is connected to the second curved segment 2211, and the end of the fifth straight segment 2213 away from the second curved segment 2211 is connected to the third straight wall 211e. Thus, the fourth straight segment 2212, the fifth straight segment 2213, the extension segment 2214, and the third straight segment 2115 can enclose and form a closed shape. As will be readily understood, this closed shape is the projection of the mounting cavity 250 in the first direction. In this embodiment, the second cover 221 can also be detachably connected to the first cover 211 via two fixing bars 222. The two fixing bars 222 can be respectively disposed at the ends of the fourth and fifth straight walls 221b and 221c away from the curved walls of the second cover 221. The two fixing bars 222 are respectively connected to the third straight wall 211e of the first cover 211. Exemplarily, the fixing strip 222 and the first cover body 211 may be snap-fitted or connected via fasteners. The specific connection method may refer to the description in the aforementioned embodiment and will not be repeated here.

[0084] Figure 15 is a schematic diagram of the assembly structure of another antenna 200 and a mast 100 according to an embodiment of the present application, and Figure 16 is a partially exploded schematic diagram of the antenna 200 and mast 100 shown in Figure 15 . Referring to Figures 15 and 16 , in this embodiment of the present application, the antenna 200 can also include a first radome 210 and a second radome 220. At least one of the first radome 210 and the second radome 220 has a radiating element 230 disposed therein. The specific structures of the first radome 210 and the second radome 220 can also be designed in accordance with the aforementioned embodiments. Unlike the aforementioned embodiments, in this embodiment, there can be multiple second antenna covers 220, arranged along a first direction, with intervals between adjacent second antenna covers 220. For example, Figures 15 and 16 illustrate an example in which two second antenna covers 220 are provided.

[0085] In this embodiment, the heights of the second antenna covers 220 can be the same or different, and this application does not impose any restrictions on this. Each second antenna cover 220 and the first antenna cover 210 include a mounting cavity 250 when connected. The multiple mounting cavities 250 are arranged in a first direction, and the holding pole 100 is sequentially inserted into the multiple mounting cavities 250. This design of the antenna 200 can be applied to a base station having a supporting structure such as an antenna 200 pole or an antenna 200 tower, such as the base station shown in Figure 3. In this case, the holding pole 100 is fixed to the supporting structure via two cross bars 600, one end of which is fixedly connected to the supporting structure, and the other end of the cross bar 600 is fixedly connected to the holding pole 100 through the gap between adjacent second antenna covers 220.

[0086] Figure 17 is a schematic diagram of the assembly structure of another antenna 200 and mast 100 according to an embodiment of the present application, and Figure 18 is a partially exploded schematic diagram of the antenna 200 and mast 100 shown in Figure 17 . Referring to Figures 17 and 18 , in this embodiment of the present application, antenna 200 may also include a first radome 210 and a second radome 220. At least one of the first radome 210 and the second radome 220 may contain a radiating element 230. The specific structures of the first radome 210 and the second radome 220 may also be designed in accordance with the aforementioned embodiments. Similar to the embodiment shown in Figures 15 and 16 , in this embodiment, multiple second antenna radomes 220 may be provided. The multiple second antenna radomes 220 are arranged along a first direction, with intervals between adjacent second antenna radomes 220. Figures 17 and 18 illustrate an example in which three second antenna radomes 220 are provided.

[0087] In this embodiment, the heights of the second antenna covers 220 can be the same or different. For example, the figure shows an example in which the middle second antenna cover 220 is taller and the second antenna covers 220 at the ends are shorter. Each second antenna cover 220 can enclose a mounting cavity 250 with the first antenna cover 210. Multiple mounting cavities 250 are arranged in a first direction, and the mast 100 is sequentially inserted into the multiple mounting cavities 250. This antenna 200 design can be used in a base station having a support structure such as an antenna pole or tower, such as the base station shown in Figure 4. In this case, the mast 100 is secured to the support structure via two crossbars 600. One end of each crossbar 600 is fixedly connected to the support structure, and the other end of each crossbar 600 is fixedly connected to the mast 100 through the gap between adjacent second antenna covers 220.

[0088] In addition, in each embodiment shown in Figures 15 to 18, among the multiple second antenna covers 220 arranged along the first direction, the top of one (the topmost one) second antenna cover 220 is coplanar with the top of the first antenna cover 210, and the bottom of another (the bottommost one) second antenna cover 220 is coplanar with the bottom of the first antenna cover 210. In this way, except for the gap between adjacent second antenna covers 220, other positions of the antenna 200 can wrap the pole 100, thereby improving the structural stability of the pole 100 and the base station as a whole.

[0089] Figure 19 is a schematic diagram of a partial structure of a base station 1000 provided in an embodiment of the present application. Referring to Figure 19, in an embodiment of the present application, the base station 1000 may further include a radio frequency processing unit 700 and a baseband processing unit 800. The radio frequency processing unit 700 is connected to the feed network of the antenna 200, and the baseband processing unit 800 is connected to the radio frequency processing unit 700. The radio frequency processing unit 700 may be used to perform frequency selection, amplification, and frequency conversion processing on the electromagnetic wave signal received by the antenna 200, and convert it into a baseband signal and send it to the baseband processing unit 800. Alternatively, the radio frequency processing unit 700 is used to convert the baseband signal of the baseband processing unit 800 into an electromagnetic wave after up-conversion and amplification processing and send it out through the antenna 200. The baseband processing unit 800 is used to process and modulate and demodulate the baseband signal. In some embodiments, the radio frequency processing unit 700 may also be referred to as a remote radio unit (RRU), and the baseband processing unit 800 may also be referred to as a baseband unit (BBU).

[0090] The RF processing unit 700 and the baseband processing unit 800 may be connected via a connecting wire. In one possible embodiment, the RF processing unit 700 and the baseband processing unit 800 may be located at a distal end of the antenna 200. In another possible embodiment, the RF processing unit 700 may be integrally provided with the antenna 200, and the baseband processing unit 800 may be located at a distal end of the antenna 200. In this example, the RF processing unit 700 and the antenna 200 may be collectively referred to as an active antenna unit (AAU).

[0091] 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.
