Reflective boundary, manufacturing method of reflective boundary, and antenna

Abstract

A reflective boundary comprises a reflective plate and a spacer, The separator has a side plate and a connecting plate formed by bending relative to the side plate. The reflecting plate and the connecting plate are respectively formed with a convex part and a through hole, and the convex part can be fitted and inserted with the through hole. The convex part can be deformed in the through hole to rivet and consolidate the connecting plate and the reflecting plate together. The reflective boundary, on the one hand, the use of screws, On the other hand, the rivet connector is convenient to manufacture, and the thickness of the reflector plate need not be increased compared with the metal integrated forming scheme, which is conducive to the lightweight design of the rivet connector. The invention also discloses an antenna including the reflective boundary and a manufacturing method of the reflective boundary.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a reflection boundary, a method for making the reflection boundary and an antenna. Background technique [0002] In mobile communication network coverage, the antenna is the basic device for sending and receiving signals, and the reflection boundary is the most basic and important unit in the antenna. The reflection boundary not only determines the realization of antenna circuit performance and radiation performance, but also plays a decisive role in structural strength and product weight. [0003] Reflective boundaries typically include reflective panels and spacers. At present, the technical solution generally adopted in the prior art is a technical solution in which the spacer and the reflection plate are formed separately and fixed by separate mechanical connectors (such as screws and rivets). In this technical solution, if screws are used as the connecting parts, on the o...

Problems solved by technology

However, this technical solution has a limit between the thickness of the electromagnetic reflector and its size. The larger the size of the part, the correspondingly larger the wall thickness

In engineering practice, in order to obtain better part size and shape accuracy, the wall thickness of the basic electromagnetic reflector is often required to select a larger value, and the excessive wall thickness of the reflective boundary will lead to overweight products, which is not conducive to realizing the lightweight requirements of the antenna; and In the process of metal integral molding of the basic electromagnetic reflector, since holes need to be preset for the installation of radiation units on the antenna, microwave devices, etc., the positions where holes need to be formed are very unfavorable to the metal flow during the molding process, so often It is necessary to adjust the method of obtaining the holes, thereby increasing the processing cost of the finished product
