Description

Technical Field

[0001] The present invention relates to the field of mobile communication technologies, and particularly to an antenna reflector and an antenna using the same. Background Art

[0002] With the rapid development of mobile communication technologies, in the current environment where 2G, 3G, 4G, and 5G networks coexist, along with the difficulty in site selection for base stations, multi-band shared antennas that support different frequency bands have become the first choice for base station antennas. However, as the number of antenna frequency bands increases, higher integration of the antenna is required, which means that the weight borne by the antenna reflector is getting larger and larger. For heavier antennas, when encountering vibration or impact, the antenna reflector may be deformed or even cracked.

[0003] Currently, to improve the strength and stiffness of the antenna reflector, it is generally achieved by directly increasing the thickness of the reflector, but the cost performance of this solution is very low, significantly increasing the weight and cost of the antenna. Another solution is to use materials with better performance to make the antenna reflector. For example, it is made by integrally pultruding with 6-series aluminum alloy. This not only increases the material cost but also requires a specially customized forming mold, has low versatility, and cannot use a numerical control punching machine for drilling, resulting in low production efficiency. Summary of the Invention

[0004] The primary objective of the present invention is to provide an antenna reflector with high structural strength.

[0005] Another objective of the present invention is to provide an antenna using the above antenna reflector.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] As a first aspect, the present invention relates to an antenna reflector, including a bottom plate and two side plates formed by bending both sides of the bottom plate in the longitudinal direction and located on the same surface of the bottom plate. The side plates include at least two reinforcing plates connected in sequence along the direction away from the bottom plate, and there is an included angle between adjacent two of the reinforcing plates.

[0008] Preferably, the reinforcing plate farthest from the bottom plate is defined as the first reinforcing plate, and a plurality of connection holes arranged along the longitudinal direction of the bottom plate are formed on the first reinforcing plate.

[0009] Preferably, the antenna reflector further includes at least one boundary plate connected to the first reinforcing plate through the connection holes.

[0010] Furthermore, the cross-section of the boundary plate along the longitudinal direction of the bottom plate is L-shaped, and its bottom end is riveted to the connection hole through a plastic rivet to be fixed relative to the first reinforcing plate.

[0011] Preferably, the number of boundary plates on the first reinforcing plate located in the two side plates is the same.

[0012] Preferably, the antenna reflector further includes a reinforcing connecting member connected to the first reinforcing plate through the connecting holes, and both ends of the reinforcing connecting member are respectively connected to the first reinforcing plates in the two side plates.

[0013] Preferably, the first reinforcing plate is parallel to the bottom plate.

[0014] Preferably, the bottom plate and the side plates are integrally formed of aluminum alloy material.

[0015] Preferably, the antenna reflector further includes an end plate provided at one end in the longitudinal direction of the bottom plate and used for setting a feeder joint, and the end plate is formed by bending the bottom plate.

[0016] As a second aspect, the present invention further relates to an antenna, including the above antenna reflector and a radiation unit mounted on the antenna reflector.

[0017] Compared with the prior art, the solution of the present invention has the following advantages:

[0018] 1. The side plates of the antenna reflector provided by the present invention include at least two reinforcing plates with an included angle. By improving the structure of the side plates, the antenna reflector forms a semi-frame structure, which can effectively improve the strength and stiffness of the antenna reflector, enabling it to bear a greater weight and not deform or even crack when applied to a high-integration antenna.

[0019] 2. In the side plates of the antenna reflector provided by the present invention, a plurality of connecting holes are provided on the first reinforcing plate far from the bottom plate. Boundary plates can be configured through the connecting holes when needed to adjust the horizontal beam width of the antenna using the antenna reflector, improve the radiation pattern, and enhance the radiation performance; or a reinforcing connecting member can be configured through the connecting holes to connect the two side plates, further enhancing the strength of the overall structure.

[0020] 3. In the antenna reflector provided by the present invention, the end plate and the bottom plate are integrally formed, ensuring the structural strength of the end plate, enabling it to bear most of the gravity of the feeder, and reducing costs and assembly processes.

[0021] Additional aspects and advantages of the present invention will be given in part in the following description, and these will become apparent from the following description or be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the drawings below are exemplary and are only used to explain the present invention and cannot be construed as a limitation to the present invention.

[0027] Those skilled in the art of the present technology can understand that unless specifically stated, the term "including" used in the description of the present invention means the presence of the described features, integers, steps, operations, components and / or assemblies, but does not exclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies and / or their groups.

The term "and / or" used here includes all or any unit and all combinations of one or more related listed items.

[0028] As Figure 1 shown in the figure, an embodiment of the present invention provides an antenna reflector 1, which includes a bottom plate 11 and two side plates 12 respectively disposed on both sides of the longitudinal direction of the bottom plate 11. The two side plates 12 are both formed by bending the bottom plate 11 and are located on the same side of the bottom plate 11, that is, the side plates 12 and the bottom plate 11 are integrally formed, reducing the setting of connection structures to improve the overall strength of the antenna reflector 1.

[0029] Please refer to Figure 2 , the side plate 12 includes two reinforcing plates 121 that are sequentially connected in a direction away from the bottom plate 11 and have an included angle with each other. The reinforcing plate 121 connected to the bottom plate 11 can improve the strength and stiffness of the bottom plate 11, and by setting another reinforcing plate 121, the strength and stiffness of the reinforcing plate 121 connected to the bottom plate 11 can be improved. That is, by improving the structure of the side plate 12, the antenna reflector 1 forms a semi-frame structure, which can effectively improve the strength and stiffness of the overall structure of the antenna reflector 1, enabling it to bear a greater weight and not deform or even crack when applied to a high-integration antenna.

[0030] Preferably, the two side plates 12 are symmetrically arranged with respect to the central axis of the bottom plate 11, and in the two reinforcing plates 121 of the bottom plate 11 and any one side plate 12, the included angle between adjacent two plate members is 90 degrees, which is convenient for production and manufacturing and has high strength.

[0031] It should be understood that in other embodiments, the side plate 12 may further include more than two of the reinforcing plates 121, and the strength of the antenna reflector 1 is further increased through the side plate structure with multiple bends. Secondly, the two side plates 12 are also of an asymmetric structure, and the included angle between adjacent two plate members in the bottom plate 11 and the side plate 12 may also be set to other angles to flexibly adjust and adapt to different product structure and strength requirements.

[0032] As Figure 1 shown, the reinforcing plate 121 farthest from the bottom plate 11 is defined as the first reinforcing plate 1211, and a plurality of connection holes 100 arranged along the longitudinal direction of the bottom plate 11 are formed in the first reinforcing plate 1211, and the connection holes 100 are used for arranging other accessories on the side plate 12. For example, a boundary plate 13 (shown in Figure 3 ) can be arranged through the connection holes 100 when needed to adjust the horizontal beam width of the antenna using the antenna reflector 1, improve the pattern, and improve the radiation performance. Or a reinforcing connecting piece (not shown in the figure, the same below) can be arranged through the connection holes 100 to connect the two side plates 12 to further enhance the strength of the overall structure.

[0033] As Figure 3 shown, in another embodiment, the antenna reflector 1 further includes at least one boundary plate 13 connected to the first reinforcing plate 1211 through the connection hole 100. The cross-section of the boundary plate 13 along the longitudinal direction of the bottom plate 11 is L-shaped, and its bottom end is riveted to the connection hole 100 through a plastic rivet to be fixed relative to the first reinforcing plate 1211. The structure, size, quantity and position of the boundary plate 13 can all be adjusted according to different frequency band parameter requirements in the antenna using the antenna reflector 1, so as to effectively improve the radiation performance of the antenna through the boundary plate 13.

[0034] Preferably, the number of boundary plates 13 on the first reinforcing plate 1211 located in the two side plates 12 is the same, so as to make the boundary environment on both sides of the antenna system consistent, which is beneficial to antenna beam shaping and electrical performance debugging.

[0035] Preferably, the antenna reflector 1 further includes a reinforcing connecting member connected to the first reinforcing plate 1211 through the connecting hole 100. Both ends of the reinforcing connecting member are respectively connected to the first reinforcing plates 1211 in the two side plates 12. The first reinforcing plates 1211 in the two side plates 12 are connected by the reinforcing connecting member, so that the antenna reflector 1 forms a frame structure with a rectangular cross-section, further enhancing the strength of the antenna reflector 1.

[0036] Preferably, the reinforcing connecting member is made of plastic or other insulating materials that do not affect the antenna radiation environment, and multiple such members can be provided. Both ends of the reinforcing connecting member can be respectively connected to the opposite connecting holes 100 in the two first reinforcing plates 1211, that is, the reinforcing connecting member is arranged along the width direction of the bottom plate 11, and multiple reinforcing connecting members are parallel to each other to ensure balanced stress on the two side plates 12. In other embodiments, multiple reinforcing connecting members can also be arranged in a cross pattern.

[0037] Preferably, the first reinforcing plate 1211 is parallel to the bottom plate 11, so as to configure the boundary plate 13 and / or the reinforcing connecting member through the connecting hole 100.

[0038] Preferably, both the bottom plate 11 and the side plates 12 are made of aluminum alloy material, which can reduce the weight and have high strength. Since the side plates 12 include two reinforcing plates 121, the strength and stiffness of the antenna reflector 1 can be enhanced. Compared with using other materials or production processes with better performance to manufacture the antenna reflector 1, the production efficiency can be improved and the production cost can be reduced.

[0039] Preferably, the antenna reflector 1 further includes an end plate (not shown in the figure, the same below) provided at one end in the longitudinal direction of the bottom plate 11 and used for setting the feeder joint. The end plate is formed by bending the bottom plate 11. The end plate and the bottom plate 11 are integrally formed, which can ensure the structural strength of the end plate, enable it to bear most of the gravity of the feeder, and can reduce costs and reduce the assembly process.

[0040] As a second aspect, the present invention also relates to an antenna (not shown in the figure, the same below), including the above antenna reflector 1 and a radiation unit mounted on the antenna reflector 1.

[0041] Since the side plates 12 include two reinforcing plates 121 with an included angle, the strength of the antenna reflector 1 can be effectively improved, ensuring its bearing capacity. There is no need to use other high-strength materials, thus ensuring the stability and durability of the antenna, and reducing the production cost of the antenna. Secondly, since multiple connecting holes 100 are provided on the first reinforcing plate 1211, the antenna can be configured with the boundary plate 13 and the reinforcing connecting member as required to adjust its radiation performance or structural strength, with wide applicability.

[0042] The above are only some embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
