[0004] Chinese patent CN 105244628 A describes an integrated integrated reflector. This reflector combines the traditional U-shaped reflector and phase shifter cavity into an integrated structure. There are no holes on the back of the reflector, which reduces the rear Radiation improves the front-to-back ratio, but the front-to-back ratio needs to be further optimized after miniaturization

Abstract

The invention relates to the field of mobile communication, and more specifically relates to a reflection plate. The reflection plate comprises a reflection plate surface, as well as left and right side plates fixed on the two sides of the reflection plate surface, a cavity structure and a metal plate extension structure, wherein the cavity structure is fixed below the reflection plate surface, and the metal plate extension structure is fixed on the outer side of the bottom of the cavity structure. According to the reflection plate disclosed by the invention, due to the arrangement of the leftand right side plates, the cavity structure and the metal plate extension structure, the reflection plate has an excellent front and back ratio, the antenna design is more concise, the assembly is reduced, the production is convenient, and the cost is reduced.

Description

technical field [0001] The present invention relates to the field of mobile communication, and more specifically, to a reflector. Background technique [0002] With the development of mobile communications, the miniaturization of base station antennas is the direction of its development. The system communication capacity continues to increase, and the distance between base stations is getting smaller and smaller. In order to reduce the mutual interference between cells, an effective method is Improve the front-to-back ratio of the base station antenna, but after the antenna is miniaturized, it is difficult to guarantee the front-to-back ratio of the antenna because it is 30dB. Even with a good radiator, it is difficult to make the front-to-back ratio of the antenna better than 25dB, let alone better than 30dB. [0003] Chinese patent CN 105633594 A describes an antenna reflector (100), including a bottom plate (101); a pair of side plates (102a, 102b) arranged on both sides...
