High-gain low-scattering angle reflective surface loaded with gradient corrugation

Abstract

The invention discloses a gradient ripple loaded high-gain and low-scattering included angle reflection surface, and aims at solving the problems of low gain and high scattering characteristic of the traditional reflection surface. The gradient ripple loaded high-gain and low-scattering included angle reflection surface comprises a reflection surface body (1) and a ripple structure (2); the reflection surface body (1) is of an L-shaped structure formed by connecting two metal plates (11) which are perpendicular to each other; the ripple structure (2) is arranged at the inner side of the reflection surface (1) and comprises a feed end ripple section (21), a first transition ripple section (22), a second transition ripple section (23) and a radiation end ripple section (24) which are sequentially heightened; each ripple section includes three metal sheets of the same specification; all metal sheets are parallel and at equal spacing and are all perpendicular to a metal plate (11). The gradient ripple loaded high-gain and low-scattering included angle reflection surface has the advantages of being high in gain and low in positive scattering characteristic under the working frequency of 8 to 12GHz, and capable of being applied to the fields such as the wireless communication field.

Description

technical field [0001] The invention belongs to the field of wireless communication, and relates to a high-gain and low-scattering angle reflective surface loaded with gradual corrugation. technical background [0002] Reflector technology has a wide range of applications in satellite communications, radar, radio astronomy and other fields. Among them, the traditional angle reflective surface has the characteristics of simple structure and good orientation. [0003] However, there are still some defects in the design of the traditional angled reflector, which are mainly reflected in the following two aspects: 1. The working principle of the traditional angled reflector is to reflect the electromagnetic waves generated by the omnidirectional feed antenna through two metal plates to achieve improved The function of gain and directional radiation, but the radiated electromagnetic wave is inconsistent in phase at the radiation port, and cannot be completely corrected as a plane...
