Metamaterial antenna housing and antenna system

Abstract

The invention relates to a metamaterial antenna housing which adopts a multilayer metamaterial structure; the multilayer metamaterial structure comprises a first dielectric layer, two metal layers covering two opposite surfaces of the first dielectric layer respectively, and two second dielectric layers covering the two metal layers respectively; each metal layer comprises a plurality of first and second round pieces; the first round pieces are arranged in a square array manner, wherein a metal wire is connected between any two closest first round pieces; the center of each second round piece is the center of a square area formed by four metal wires connected with four closest first round pieces; and the centers of the first and the second round rounds of any metal layers are directly opposite to the centers of the first and the second round rounds of the other metal layer, so that the multilayer metamaterial structure has high wave permeability. The invention further relates to an antenna system comprising the metamaterial antenna housing.

Description

technical field [0001] The invention relates to a radome and an antenna system, more specifically, to a radome and an antenna system made of a newly designed metamaterial structure. Background technique [0002] In the antenna system, it is often necessary to use a radome to cover the antenna to protect the antenna from the influence of the harsh external environment. In this way, when the antenna sends and receives electromagnetic waves, the electromagnetic waves must pass through the radome. Although materials with low dielectric constant and loss tangent and high mechanical strength are mostly used in the manufacture of radomes, such as fiberglass, epoxy resin, ABS and UPVC and other polymers, they still cannot match the wave impedance of air. When the electromagnetic wave propagates between the air and the radome, it will not only be reflected, but also the radome will have a large loss of electromagnetic waves, thereby reducing the radiation efficiency and gain of the a...

Although materials with low dielectric constant and loss tangent and high mechanical strength are mostly used in the manufacture of radomes, such as fiberglass, epoxy resin, ABS and UPVC and other polymers, they still cannot match the wave impedance of air. When the electromagnetic wave propagates between the air and the radome, it will not only be reflected, but also the radome will have a large loss of electromagnetic waves, thereby reducing the radiation efficiency and gain of the antenna, and seriously affecting the electromagnetic performance of the antenna, that is, the transmission of the radome. poor wave performance
