Description

Technical Field

[0001] This invention relates to the field of base station antenna technology, and more particularly to a protective component and a base station antenna. Background Technology

[0002] With the continuous development of communication technology, especially the development and design of integrated multi-band antennas, a multi-band base station antenna must integrate radiating elements from multiple frequency bands in a staggered and integrated layout. Simultaneously, due to space constraints and high-altitude wind requirements, the overall dimensions of the base station antenna in the length, width, and height directions must be strictly controlled. In integrated antenna layouts, low-frequency radiating elements, due to their larger size, are often placed on both sides of the width direction. To maximize and optimize the electrical performance of low-frequency radiating elements, such as beamwidth and isolation, they are generally placed at the outermost edge, making the balun arm of the low-frequency radiating element very close to the inner wall of the base station antenna housing.

[0003] Most base station antenna shells are rectangular, and the shell material itself is easily deformed. During production, transportation, and operation, the shell is easily deformed when subjected to external pressure or flipping. The deformed shell may come into contact with the vibrator. If a large deformation occurs, it will crush the vibrator, affecting the performance indicators of the base station antenna. In more serious cases, it will lead to the complete failure of the base station antenna.

[0004] Currently, anti-collision supports are installed on the reflectors inside base station antennas. These supports are located between the outer shell and the radiating elements to protect them. When the base station antenna is large, multiple anti-collision supports are needed to support the outer shell, preventing contact between the outer shell and the radiating elements, and also preventing deformation of the base station antenna due to violent shaking. The radiating element layout inside existing multi-band integrated base station antennas is staggered, often allowing only one direction of anti-collision supports. Most supports only protect the top of the outer shell from deformation. However, during the base station antenna manufacturing process, before the outer shell is assembled, flipping the base station antenna may damage the side radiating elements, especially the balun arm welding points on the low-frequency radiating elements on the sides, affecting the intermodulation, bandwidth, and other related electrical parameters of the base station antenna.

[0005] In addition, in the outdoor environmental testing of existing base station antennas, the vibration test adds multi-directional vibration impact. Under such vibration impact, the sides and top of the base station antenna shell will be greatly deformed, which will cause damage to the radiating elements inside the base station antenna at the same time.

[0006] Therefore, it is urgent to address the defect that causes damage to the radiating element due to deformation of the base station antenna shell in multiple directions during the manufacturing and assembly process and environmental testing. Summary of the Invention

[0007] This invention provides a protective component and a base station antenna to solve the defect in the prior art where deformation of the base station antenna shell in multiple directions causes damage to the radiating element during the manufacturing and assembly process and environmental testing, thereby achieving a protective component that protects the base station antenna in multiple directions.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] Figure 1The diagram shows the positional relationship between the radiator 300 and the radome 400 in an existing base station antenna. It can be clearly seen that the radiator 300 is located on the reflector 200 near the radome 400. At the same time, the radiating balun arm 301 of the radiator 300 may be damaged by the impact of deformation from the top wall 401 and side wall 402 of the radome 400 during the manufacturing process and environmental vibration test, which may seriously affect the electrical performance of the base station antenna.

[0054] To solve the above problems, the following will combine... Figures 2-14 The protective component and base station antenna of the present invention are described.

[0055] like Figures 2 to 11 As shown, the protective component 100 provided in this embodiment of the invention includes a body 1, which includes an assembly part 11, a first support part 12, and a second support part 13. The assembly part 11 is used to fix and connect the reflector 200 of the base station antenna. The assembly part 11 includes an assembly surface 111, which is used to abut against the mounting surface of the reflector 200. The first support part 12 is spaced apart from the assembly part 11 along a first direction and is located on the side of the assembly part 11 away from the assembly surface 111. The distance between the first support part 12 and the assembly surface 111 is greater than the height of the radiating element 300 of the base station antenna. The first direction is perpendicular to the assembly surface 111, and the first support part 12 is used to provide support in the first direction. The second support part 13 is spaced apart from the assembly part 11 along a second direction, which is parallel to the assembly surface 111, and the second support part 13 is used to provide support in the second direction.

[0056] In this embodiment, an assembly part 11 is provided at one end of the main body 1 along the first direction. The assembly part 11 is used to fix the reflector 200 of the base station antenna, so that the protective member 100 can be fixedly installed on the reflector 200. A first support part 12 is provided at the other end of the main body 1 along the first direction, so that the first support part 12 and the assembly part 11 are spaced apart along the first direction, and the distance between the first support part 12 and the assembly surface 111 is greater than the height of the radiating element 300, so that when the protective member 100 is installed on the reflector 200, the first support part 12 can extend beyond the position of the radiating balun arm 301 of the radiating element 300, and the first support part 12 is close to the top wall 401 of the antenna cover 400, so that the top of the antenna cover 400 can be fixedly installed on the antenna cover 400. The top wall 401 provides support and protection, effectively preventing deformation of the top wall 401 of the radome 400 from damaging the radiating balun arm 301 of the radiator 300. At the same time, a second support portion 13 is provided at one end of the main body 1 along the second direction, and the second support portion 13 and the mounting portion 11 are spaced apart along the second direction, so that when the protective member 100 is installed on the reflector plate 200, the second support portion 13 can also extend beyond the position of the radiating balun arm 301 of the radiator 300. Furthermore, the second support portion 13 and the side wall 402 of the radome 400 are close to each other, thereby providing support and protection at the side wall 402 of the radome 400, effectively preventing deformation of the side wall 402 of the radome 400 from damaging the radiating balun arm 301 of the radiator 300.

[0057] The protective member 100 of the present invention, by providing a first support portion 12 and a second support portion 13, with the first support portion 12 and the second support portion 13 respectively located at different positions on the body 1, can provide support and protection corresponding to different directions respectively; the protective member 100 can be fixedly installed on the reflector plate 200 of the base station antenna by the assembly portion 11, so that the first support portion 12 and the second support portion 13 correspond to the top wall 401 and side wall 402 directions of the antenna cover 400 of the base station antenna respectively, and both directions exceed the radiating balun arm 3 of the radiating element 300 of the base station antenna. The position 01 allows for simultaneous support of the top wall 401 and side wall 402 of the protective radome 400, ensuring support and protection in two directions. This enables multi-directional anti-collision protection measures for the radiating element 300 during manufacturing, debugging, and environmental testing, preventing damage to the radiating element 300. This multi-directional protection of the base station antenna ensures its electrical performance and addresses the shortcomings of existing technologies where deformation of the antenna housing in multiple directions during manufacturing, assembly, and environmental testing damages the radiating element 300.

[0058] Specifically, when the base station antenna needs to be supported and protected against collisions in multiple directions, the protective component 100 can be further equipped with support parts in different directions as needed. That is, support parts can be set in places where protection is required, such as third support parts, fourth support parts, etc., to increase protection in different directions and achieve support and protection for the base station antenna in multiple directions.

[0059] Specifically, the support surface shapes of the first support portion 12 and the second support portion 13 are adapted to the inner wall shapes of the top wall 401 and side wall 402 of the radome 400 that needs to be supported and protected, which can effectively increase the protection range. For example, the support surface of the first support portion 12 is an inclined surface adapted to the top wall 401, and the support surface of the second support portion 13 is an arc surface adapted to the side wall 402.

[0060] Specifically, such as Figures 2 to 7 and Figure 11 As shown, the assembly part 11 also includes a first connecting part 112 and a second connecting part 113. The first connecting part 112 and the second connecting part 113 are both protruding from the assembly surface 111 and are arranged at intervals along the second direction. The first connecting part 112 and the second connecting part 113 are both used for detachable connection with the reflector 200.

[0061] like Figure 9 As shown, a base station antenna may include multiple radiating elements 300, such as a first radiating element 302 and a second radiating element 303. Typically, the first radiating element 302 and the second radiating element 303 in the base station antenna are arranged compactly, meaning the protective component 100 can only be installed in the middle of the first radiating element 302 and the second radiating element 303. Simultaneously, the protective component 100 is usually located on the side of the reflector 200 to provide a wider protection range. From an overall layout perspective, the installation space for the protective component 100 is relatively small.

[0062] In this embodiment, a first connecting portion 112 and a second connecting portion 113 arranged at intervals along the second direction are used to fix the protective component 100 and the reflector 200. The two-point fixing saves installation space, has a compact structure, and effectively solves the problem of insufficient installation space.

[0063] In one embodiment, such as Figures 2 to 7 As shown, the first connecting part 112 includes a hook, and the second connecting part 113 includes an elastic buckle, wherein the hook opening 1121 is disposed facing the elastic buckle.

[0064] In this embodiment, both the hook and the elastic buckle are located below the mounting surface 111. The hook is shaped like the letter C, forming a C-shape. The elastic buckle is spaced a certain distance from the C-shaped hook. For example, in the second direction, the C-shaped hook is located at the end of the mounting part 11 closer to the second support part 13, and the elastic buckle is located at the end away from the second support part 13. By adopting the combined installation structure of the C-shaped hook and the elastic buckle, the protective component 100 is easy and convenient to install. Compared with the conventional method of using a rotating buckle or a combination of two elastic buckles for fixing, the combination of the C-shaped hook and the elastic buckle can increase the stability of the fixation, which is beneficial to ensuring the support and protection effect.

[0065] Specifically, such as Figure 11 As shown, corresponding mounting holes are provided on the reflector 200 of the base station antenna for mounting the protective component 100; wherein, the mounting holes include square slots 201 and round slots 202, the square slots 201 are used for mounting with C-shaped hooks, and the round slots 202 are used for mounting with elastic buckles.

[0066] In one embodiment, the end of the latch 1121 of the hook is provided with a guide slope. The guide slope is an angled inclined slope that can play a guiding role, so that the hook can be assembled with the square hole 201 of the reflector 200 when the protective component 100 is installed, and the body 1 can be fixed at a certain angle.

[0067] Specifically, such as Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the elastic buckle is a petal-shaped snap fastener on both sides, including the elastic buckle body in the middle and the petal spring arms symmetrically arranged on both sides of the elastic buckle body. The elastic buckle body is fixedly connected to the assembly surface 111. The petal spring arms have an arc-shaped structure and strong elasticity. The petal spring arms are used to engage with the round hole groove 202 to secure and fix the connection firmly and stably.

[0068] Specifically, such as Figure 10 and Figure 11 As shown, multiple mounting holes can be set on the reflector 200 of the base station antenna as needed, allowing for the installation of multiple protective components 100.

[0069] In one specific embodiment, when the protective component 100 is installed on the reflector 200, the C-shaped hook of the protective component 100 is first inserted into the square slot 201 at a certain angle. Through the guide slope at the front end, the C-shaped hook completes the engagement and connection with the square slot 201 of the reflector 200. At the same time, during the assembly process, after the elastic buckle passes through the round slot 202 on the reflector 200, the petal arms on both sides of the elastic buckle open, so that the elastic buckle is fixed in the corresponding position on the reflector 200.

[0070] In one embodiment, such as Figures 2 to 7 As shown, the assembly part 11 also includes a reinforcing support part 114, which protrudes along a third direction and is disposed on both sides of the assembly part 11. The third direction is perpendicular to the first direction and the second direction, and the bottom surface of the reinforcing support part 114 is flush with the assembly surface 111.

[0071] In this embodiment, by providing reinforcing support portions 114 that protrude from opposite sides of the assembly portion 11, the lateral stability of the protective component 100 after installation can be increased, thereby increasing the installation stability in multiple directions, reducing shaking after installation, and effectively improving the stability of the support protection.

[0072] In one specific embodiment, the reinforcing support 114 is a reinforcing rib.

[0073] In one embodiment, such as Figures 2 to 7 As shown, the main body 1 also includes a first direction support arm 14 and a second direction support arm 15. One end of the first direction support arm 14 and the second direction support arm 15 are respectively connected to the two ends of the assembly part 11, and the other ends of the first direction support arm 14 and the second direction support arm 15 are connected to each other. Thus, the assembly part 11, the first direction support arm 14 and the second direction support arm 15 are connected to form the frame on the main body 1. The first support part 12 and the second support part 13 are respectively located in different directions on the frame of the main body 1 and are located away from the assembly part 11.

[0074] Specifically, the main body 1 also includes an inner wall panel 10 connected to the interior of the frame, and the inner wall panel 10 has weight reduction holes 101, such as two weight reduction holes 101.

[0075] In one embodiment, the body 1 further includes a first reinforcing rib 102, which is disposed on the outer side of the first direction support arm 14 near the assembly part 11. The first reinforcing rib 102 is perpendicular to the first direction support arm 14 and extends along the height direction of the first direction support arm 14, i.e., the first direction, thereby reinforcing the height direction of the frame.

[0076] Furthermore, the main body 1 also includes a second reinforcing rib 103. The second reinforcing rib 103 is disposed on the opposite two sides of the first direction support arm 14 near the assembly part 11. The second reinforcing rib 103 also extends along the height direction of the first direction support arm 14 and is perpendicular to the direction of the first reinforcing rib 102. Thus, the second reinforcing rib 103 and the first reinforcing rib 102 on both sides form a stable triangular layout on the frame of the main body 1, making the structure more robust and stable. It also serves to strengthen the height direction of the frame, thereby increasing the support and reinforcement. After assembly, it can stabilize the fixation of the base station antenna in multiple directions and increase the installation stability in multiple directions.

[0077] For example, both the first reinforcing rib 102 and the second reinforcing rib 103 can be triangular reinforcing rib walls.

[0078] Furthermore, the body 1 also includes a third reinforcing rib 104, which comprises a plurality of thin-walled ribs protruding from and evenly distributed on the inner wall plate 10 of the body 1. The plurality of thin-walled ribs are evenly distributed laterally or longitudinally on the inner wall plate 10 inside the frame. The third reinforcing rib 104 effectively increases the molding capacity of the injection molded part according to the shape layout of the frame; at the same time, the direction of the third reinforcing rib 104 is perpendicular to the first direction support arm 14 or the second direction support arm 15, which can play a supporting and reinforcing role for the first direction support arm 14 and the second direction support arm 15, which is conducive to controlling the wall thickness of the body 1 and facilitating the injection molding process.

[0079] The specific distribution of the third reinforcing rib 104 is not limited. In one specific embodiment, the third reinforcing rib 104 includes a portion of the wall rib arranged around the weight reduction hole 101.

[0080] By setting the first reinforcing rib 102, the second reinforcing rib 103 and the third reinforcing rib 104, the installation stability of the body 1 in multiple directions is increased accordingly, and the first direction support arm 14 and the second direction support arm 15 can be reasonably strengthened under stress.

[0081] In one embodiment, the first direction support arm 14, the second direction support arm 15, the C-shaped hook, the elastic buckle, the first reinforcing rib 102, the second reinforcing rib 103, the third reinforcing rib 104, and the assembly part 11 can be integrally molded into a frame using a mold.

[0082] Of course, in other embodiments not shown, the frame can also be formed by bonding or by fasteners, and there are no specific limitations on the way the frame is formed.

[0083] In one embodiment, the outer dimensions of the first support portion 12 and the second support portion 13 are larger than the outer dimensions of the radiation balun arm 301 of the protected radiation element 300, thereby ensuring that the radiation element 300 can be effectively protected.

[0084] In another embodiment, such as Figures 4 to 7As shown, the protective component 100 also includes an adjustable support body 2. The adjustable support body 2 is disposed on the first support portion 12 and has a first extended state and a first retracted state. In the first extended state, a portion of the adjustable support body 2 extends out of the first support portion 12 in a first direction, and in the first retracted state, the adjustable support body 2 retracts to the first support portion 12; and / or, the adjustable support body 2 is disposed on the second support portion 13 and has a second extended state and a second retracted state. In the second extended state, a portion of the adjustable support body 2 extends out of the second support portion 13 in a second direction, and in the second retracted state, the adjustable support body 2 retracts to the second support portion 13.

[0085] In this embodiment, under special circumstances such as a compact base station antenna layout, the installation position of the protective component 100 is affected, making it difficult for the shape of the first support portion 12 and the second support portion 13 of the body 1 of the protective component 100 to exceed the radiating balun arm 301 of the protected radiating element 300. In this case, by adding adjustable supports 2 to the first support portion 12 and the second support portion 13 respectively, the height of the protective component 100 can be increased using the adjustable supports 2, ensuring the protective function is achieved. This allows for support protection at different heights, increasing the utilization rate of the protective component 100. The protective component 100 in this embodiment can adjust its height in multiple directions according to the actual needs of the base station antenna, achieving a multi-directional height-adjustable protective component 100. This protects the base station antenna in multiple directions, adapting to various height requirements and meeting the needs of base station antennas in different usage scenarios. It has strong versatility and meets the future development needs of multi-port base station antennas.

[0086] Depending on the usage requirements, an adjustable support body 2 can be added only to the first support part 12 to achieve adjustable support for the top of the protective component 100; an adjustable support body 2 can be added only to the second support part 13 to achieve adjustable support for the side of the protective component 100; or an adjustable support body 2 can be added to both the first support part 12 and the second support part 13 to achieve adjustable support for both the top and side of the protective component 100.

[0087] Specifically, both the main body 1 and the adjustable support 2 are injection molded from non-metallic materials, such as plastic, which can effectively reduce the mutual adjustment effect.

[0088] Specifically, the adjustable support 2 can have multiple first extended states and multiple second extended states to adjust the length of the adjustable support 2 extending from the first support part 12 and the second support part 13. That is, the adjustable support 2 can extend from the first support part 12 and the second support part 13 at multiple different heights to meet the needs of the base station antenna to adapt to various different height requirements.

[0089] Specifically, such as Figures 12 to 14 As shown, the adjustable support 2 includes an adjustable connecting part 21.

[0090] like Figures 4 to 7 As shown, the main body 1 also includes a first mounting part 16, which is disposed at the first support part 12 and extends along the first direction. The adjustable connecting part 21 is connected to the first mounting part 16 and has a plurality of first connecting positions along the extending direction of the first mounting part 16. The plurality of first connecting positions correspond to the first extended state and the first retracted state, respectively.

[0091] And / or, the body 1 also includes a second mounting part 17, which is disposed at the second support part 13 and extends along the second direction. The adjustable connecting part 21 is connected to the second mounting part 17 and has a plurality of second connecting positions along the second mounting part 17. The plurality of second connecting positions correspond to the second extended state and the second retracted state, respectively.

[0092] In this embodiment, when the adjustable support body 2 is provided on the first support part 12, it is connected to the first mounting part 16 through the adjustable connecting part 21 to realize the installation of the adjustable support body 2 and the first support part 12 of the body 1. At the same time, by setting multiple first connection positions, the first extended state and the first retracted state of the adjustable support body 2 can be switched, and the height dimension can also be changed. When the adjustable support body 2 is provided on the second support part 13, it is connected to the second mounting part 17 through the adjustable connecting part 21 to realize the installation of the adjustable support body 2 and the second support part 13 of the body 1. At the same time, by setting multiple second connection positions, the second extended state and the second retracted state of the adjustable support body 2 can be switched, and the height dimension can also be changed to meet the actual use requirements.

[0093] Specifically, such as Figures 12 to 14 As shown, the end of the adjustable connecting part 21 is provided with a limiting part 22.

[0094] like Figures 4 to 7 As shown, the first mounting part 16 is provided with a plurality of first positioning parts 161. The plurality of first positioning parts 161 are arranged along the extension direction of the first mounting part 16 and correspond one-to-one with a plurality of first connection positions. The limiting part 22 is selectively connected to one of the plurality of first positioning parts 161 to fix the adjustable connection part 21 to the first mounting part 16.

[0095] And / or, the second mounting part 17 is provided with a plurality of second positioning parts 171, the plurality of second positioning parts 171 are arranged along the extension direction of the second mounting part 17 and correspond one-to-one with a plurality of second connection positions, and the limiting part 22 is selectively connected to one of the plurality of second positioning parts 171 to fix the adjustable connection part 21 to the second mounting part 17.

[0096] In this embodiment, by setting the limiting part 22 to cooperate with the first positioning part 161, the connection position between the adjustable connecting part 21 and the first mounting part 16 can be limited, thereby limiting the extension and retraction state and height of the adjustable support body 2 relative to the first support part 12; by setting the limiting part 22 to cooperate with the second positioning part 171, the connection position between the adjustable connecting part 21 and the second mounting part 17 can be limited, thereby limiting the extension and retraction state and height of the adjustable support body 2 relative to the second support part 13, thus meeting the actual use requirements.

[0097] In one embodiment, such as Figures 4 to 7 As shown, the first mounting part 16 and the second mounting part 17 include slots, and the first positioning part 161 and the second positioning part 171 are fixing slots provided inside the slots; as Figures 12 to 14 As shown, the limiting part 22 includes a stop buckle 221 that protrudes from the outside of the insertion end of the adjustable connecting part 21. The stop buckle 221 engages with the fixed slot to insert the adjustable connecting part 21 into the slot.

[0098] In this embodiment, the first mounting part 16 and the second mounting part 17 are slots formed on the main body 1. The slot entrances are located on the first support part 12 and the second support part 13, respectively. The adjustable connecting part 21 is inserted into the slot, thereby realizing the installation of the adjustable support 2 at the first support part 12 and the second support part 13. A fixed slot is also provided in the slot, and a stop buckle 221 is provided on the adjustable connecting part 21. The stop buckle 221 cooperates with the fixed slot to fix the connection, thereby realizing the fixed connection between the adjustable support 2 and the main body 1, and limiting the installation position and extension height of the adjustable support 2. At the same time, by arranging multiple fixed slots according to certain requirements with different height spacing, the adjustable support 2 can be installed in different positions, realizing the adjustment of the extension height of the adjustable support 2. This ensures that the protective component 100 can have multiple height dimensions by adjusting the assembly, which can meet the dimensional changes in the height direction and the height adjustment in multiple directions, meet the use of multiple different antennas, adapt to installation in different environments, increase the scope of use, and ensure the support and protection effect of the protective component 100.

[0099] Specifically, the slot is located on the inner wall panel 10 inside the frame of the main body 1.

[0100] In one embodiment, such as Figures 4 to 6 , Figure 12 and Figure 13As shown, the stop buckle 221 includes a first spring buckle 2211 and a second spring buckle 2212. Both the first spring buckle 2211 and the second spring buckle 2212 have a stop surface, and the stop surfaces of the first spring buckle 2211 and the second spring buckle 2212 face opposite directions along the extension direction of the adjustable connection part 21. This restricts the adjustable connection part 21 from wobbling along the extension direction of the slot when the stop buckle 221 is assembled into the fixing slot in the slot, thereby increasing the firmness and reliability of the connection.

[0101] In one specific embodiment of this example, both the first snap fastener 2211 and the second snap fastener 2212 are single triangular snap fasteners, but they are oriented in opposite or perpendicular directions, that is, the stop surfaces face opposite directions. Furthermore, the first snap fastener 2211 and the second snap fastener 2212 are located on opposite sides of the adjustable connecting portion 21.

[0102] In another embodiment, such as Figure 7 and Figure 14 As shown, multiple limiting parts 22 are provided along the extension direction of the adjustable connecting part 21. Each limiting part 22 includes two stop buckles 221 disposed on opposite sides of the adjustable connecting part 21. When the adjustable connecting part 21 is inserted into the slot, the multiple stop buckles 221 respectively cooperate with the multiple fixed slots to engage, further increasing the firmness and reliability of the connection and fixing, and making it stable and not easy to shake.

[0103] In one specific embodiment of this example, the stop buckle 221 is an arc-shaped buckle with a hemispherical cross-section, and the fixing slot is an arc-shaped groove.

[0104] Specifically, such as Figures 4 to 7 , Figures 12 to 14 As shown, the adjustable support 2 also includes a support plate 23, which is connected to the extended end of the adjustable connecting part 21. In the first retracted state, the support surface of the support plate 23 along the first direction is flush with or recessed in the support surface of the first support part 12; in the second retracted state, the support surface of the support plate 23 along the second direction is flush with or recessed in the support surface of the second support part 13.

[0105] In this embodiment, by setting the support plate 23, the support and protection area of ​​the adjustable support body 2 is increased, which can effectively increase the protection range. At the same time, by setting it in the retracted state, the support surface of the support plate 23 is flush with or relatively concave with the support surfaces of the first support part 12 and the second support part 13, so that the adjustable connection part 21 is completely connected to the first mounting part 16 and the second mounting part 17, ensuring the support and protection effect of the first support part 12 and the second support part 13 in the first retracted state and the second retracted state.

[0106] Specifically, when the adjustable support 2 is provided on the first support part 12, the shape of the support surface of the support plate 23 is the same as or close to the shape of the support surface of the first support part 12 of the main body 1, which facilitates assembly. For example, the support surface of the support plate 23 and the support surface of the first support part 12 are both inclined planes, which are suitable for protecting the top wall 401 of the antenna cover 400.

[0107] When the adjustable support 2 is provided on the second support part 13, the shape of the support surface of the support plate 23 is the same as or close to the shape of the support surface of the second support part 13 of the main body 1, which facilitates assembly. For example, the support surface of the support plate 23 and the support surface of the second support part 13 are both in the shape of a middle plane and arc surfaces at the top and bottom ends, which is suitable for protecting and supporting the side wall 402 of the antenna cover 400.

[0108] On the other hand, such as Figures 8 to 11 As shown, this embodiment of the invention also provides a base station antenna, including a reflector 200, a radiating element 300, an antenna cover 400, and a protective component 100 provided by any of the above embodiments. The radiating element 300 and the protective component 100 are both mounted on the reflector 200, and the antenna cover 400 is connected to the reflector 200 and covers the outside of the radiating element 300 and the protective component 100.

[0109] The base station antenna of the present invention, by setting the protective component 100, can simultaneously support the top wall 401 and side wall 402 of the protective antenna cover 400, thereby ensuring support and protection in two directions at the same time. This realizes multi-directional anti-collision protection measures for the radiating element 300 in the base station antenna during manufacturing, debugging, and environmental testing, avoiding damage to the radiating element 300, achieving multi-directional protection of the base station antenna, ensuring the electrical performance of the base station antenna, and solving the defect in the prior art where deformation of the base station antenna shell in multiple directions during manufacturing, assembly, and environmental testing causes damage to the radiating element 300.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
