Problems solved by technology

[0002] The coverage pattern of the antenna not only includes the main lobe of the antenna and the rear lobes of the antenna located on both sides of the main lobe of the antenna, the rear lobes of the antenna are likely to cause over-area coverage and interference
In order to reduce the rear lobe of the traditional antenna with a reflector, it is necessary to increase the area of ​​the reflector or change the physical structure of the reflector. However, increasing the area of ​​the reflector will increase the installation area of ​​the antenna and the cost of the antenna, and the known change in reflection The processing of the plate structure is difficult and costly, and the effect of reducing the back lobe of the traditional solution is greatly limited

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0026] Metamaterials are artificial composite structural materials with extraordinary physical properties that natural materials do not have. Through the orderly arrangement of conductive geometric structures, the relative permittivity and magnetic permeability of each point in space can be changed. Metamaterials can realize within a certain range the refractive index, impedance, and wave-transmitting properties that ordinary materials cannot possess, so that they can effectively control the propagation characteristics of electromagnetic waves. In the present invention, by setting an array of I-shaped conductive geometric structures, the reflection surface of the antenna reflection plate is formed as a high-...

Abstract

An antenna baffle board comprises at least one metamaterial plate layer, each metamaterial plate layer comprises a base plate and a plurality of conductive geometric structures arrayed on the base plate. The conductive geometric structures comprise H-shaped structures inverted horizontally and are configured to enable the reflecting surface to form a high-resistance surface and antenna working frequency to be arranged in a stop band of the high-resistance surface. A low-back-lobe antenna comprises an antenna body and the antenna baffle board. The antenna baffle board and the antenna body are arranged in parallel and spaced. The antenna of the antenna baffle board can reduce antenna back lobe remarkably.

Description

technical field [0001] The invention relates to antenna technology, in particular to an antenna reflection plate and a low rear lobe antenna. Background technique [0002] The coverage pattern of the antenna includes not only the antenna main lobe and the antenna back lobes located on both sides of the antenna main lobe, but the antenna back lobes are likely to cause over-area coverage and interference. In order to reduce the rear lobe of the traditional antenna with a reflector, it is necessary to increase the area of ​​the reflector or change the physical structure of the reflector. However, increasing the area of ​​the reflector will increase the installation area of ​​the antenna and the cost of the antenna, and the known change in reflection The processing of the plate structure is difficult and costly, and the effect of reducing the back lobe of the traditional solution is greatly limited. Contents of the invention [0003] The object of the present invention is to ...
