Embodiment Construction

[0028] Metamaterial is an artificial composite structural material with extraordinary physical properties that natural materials do not have. Through the orderly arrangement of microstructures, the relative permittivity and permeability of each point in space can be changed. Metamaterials can achieve refractive index, impedance and wave-transmitting properties that ordinary materials cannot have within a certain range, so that the propagation characteristics of electromagnetic waves can be effectively controlled. The metamaterial radome based on the artificial microstructure can change the relative permittivity, refractive index and impedance of the material by adjusting the shape and size of the artificial microstructure, so as to achieve impedance matching with the air to maximize the incidence of incident electromagnetic waves. transmission. The frequency can be selected by adjusting the size of the microstructure, and the corresponding wave transmission and filtering frequ...

Abstract

The invention relates to a wave-transmitting meta-material and an antenna cover and an antenna system with the material. The wave-transmitting meta-material comprises a first substrate and a second substrate, wherein one layer of square patches with holes at the centers are clamped between the first substrate and the second substrate in an array manner; and circular patches which are arranged in an array manner are arranged on the outer surfaces of the first and second substrates. According to the wave-transmitting meta-material and the antenna cover and the antenna system with the material disclosed by the invention, the wave-transmitting efficiency is high, the loss is small, and the selective wave-transmitting function is realized.

Description

technical field [0001] The present invention relates to metamaterials, and more particularly, to wave-transmitting metamaterials and their radomes and antenna systems. Background technique [0002] Metamaterials, commonly known as metamaterials, are a new type of synthetic material, which is composed of a substrate made of non-metallic materials and multiple artificial microstructures attached to the surface of the substrate or embedded inside the substrate. The substrate can be virtually divided into multiple substrate units arranged in a rectangular array, and artificial microstructures are attached to each substrate unit to form a metamaterial unit. The entire metamaterial is composed of many such metamaterial units, like Crystals are made up of countless lattices in a certain arrangement. The artificial microstructures on each metamaterial unit may or may not be identical. The artificial microstructure is a plane or three-dimensional structure composed of metal wires w...
