Description
Technical Field
The invention relates to the field of mobile communication, in particular to an integrated large-size base station antenna reflecting plate.
Background
With the development of mobile communication, miniaturization, integration and cable-free design of the base station antenna are the development directions, but the frequency band for 4G mobile communication is between 690MHz and 2690MHz, and the reflection plate for high frequency band integration is relatively easy to manufacture by an aluminum profile process. For 690-960MHz antenna, the width of the reflector is approximately 300mm wide, if the aluminum extrusion process is used to manufacture an integrated reflector 300mm wide, the wall thickness is more than 3mm, and the accuracy is difficult to ensure, even if the reflector with the wall thickness of 3mm can be extruded, the antenna manufactured by using the reflector is very heavy, so that the reflector is almost impossible for the aluminum hot extrusion process, and in addition, the width of the reflector is wider for 690-960MHz and 1710-2690MHz multi-frequency antennas. This is formed integrally with the aluminum pultrusion process and is almost impossible.
Therefore, it is necessary to provide an integrated base station antenna reflector for low frequency band.

The further technical proposal is that: the angle aluminum is arranged on two sides of the reflecting plate surface, one side of the angle aluminum is connected with the reflecting plate, and the other side of the angle aluminum is used as a side wall of the reflecting plate.

Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the present patent; for the purpose of better illustrating the embodiments, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted", "connected" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected or integrally connected; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, so to speak, the two elements are communicated internally. It will be understood by those of ordinary skill in the art that the terms described above are in the specific sense of the present invention. The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.
Example 1
The embodiment discloses an integrated large-size base station antenna reflecting plate, which comprises a reflecting plate, a phase shifter cavity and angular aluminum, wherein the phase shifter cavity is arranged on the inner side surface of the reflecting plate, and comprises a first phase shifter cavity, a first phase shifter input-output end cavity, a second phase shifter input-output end cavity and a second phase shifter cavity which are sequentially connected; the phase shifter cavity and the reflecting plate are of an integrated structure; the angle aluminum is arranged on two sides of the reflecting plate surface, and the reflecting plate of the base station antenna is relatively simple to manufacture through the structural arrangement of the angle aluminum, so that the base station antenna is simpler in design, the base station antenna with a low frequency band can be designed without a cable, assembly is reduced, automatic production is facilitated, efficiency is improved, and cost is saved.
In the invention, the reflecting plate and the angular aluminum jointly form the U-shaped reflecting plate, and in order to improve the beam convergence of the horizontal plane of the antenna, the angular aluminum can be selected to have different specifications according to actual needs.
In the novel use, the large size is the condition that the width of the cavity of the phase shifter and the width of the reflecting plate are more than 180mm, in practical application, because the antenna with low frequency 690-960MHz is generally designed by a cable, the width of the reflecting plate is generally close to 300mm wide, if no cable design is required to be realized, the width of the cavity of the phase shifter behind the reflecting plate is nearly 180mm, and the width of the reflecting plate is more than 300 mm.
The modern technology stretches the reflecting plate, if the width of 300mm is required, the thickness of the reflecting plate is required to exceed 3mm, and the reflecting plate can be manufactured by an aluminum pultrusion technology, even if the aluminum pultrusion material is pulled out, the precision of the reflecting plate is difficult to reach the requirement, and the reflecting plate is very heavy and double in cost, and the thickness of the reflecting plate in actual requirements is generally 1.5mm, so that the whole machine is lighter in weight and lower in cost. Therefore, the reflector plate with large size can not meet the normal requirement while increasing the cost, so the invention adopts the mode of angle aluminum to widen the emitter plate.
As shown in FIG. 1, the corner aluminum, the insulating film and the reflecting plate are connected in a riveting mode through screw holes, so that the corner aluminum with different specifications can be replaced according to the needs, the width of the reflecting plate can be changed when antennas with different frequency bands are designed conveniently, the operation is convenient, and the design is flexible.
Example 2
As shown in FIG. 3, the corner aluminum and the reflecting plate can be connected in a welding mode, so that the corner aluminum and the reflecting plate are firmer and attractive, intermodulation problems caused by the problem of interfaces are avoided during mass production through laser process welding, a large amount of time for manually riveting the reflecting plate can be saved, and the corner aluminum and the reflecting plate can be applied to mass production.
Example 3
As shown in fig. 4, in the third embodiment of the present invention, the single-layer phase shifter cavity structure is adopted, and is formed by extrusion of aluminum profiles, so that the method is convenient, the process and time are saved, the cost is saved, and the output per unit time is larger.
In the drawings, the positional relationship is described for illustrative purposes only and is not to be construed as limiting the present patent; it is to be understood that the above examples of the present invention are provided by way of illustration only and not by way of limitation of the embodiments of the present invention.
