Embodiment Construction

[0028] Metamaterials are artificial composite structural materials with extraordinary physical properties that natural materials do not have. Through the orderly arrangement of microstructures, 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. The broadband wave-transparent metamaterial based on 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 air and maximize the incident electromagnetic wave. transmission. And the frequency can be selected by adjusting the size of the microstructure, and the corresponding wave-transmitting ...

Abstract

The invention relates to a wideband wave-transmitting metamaterial, and an antenna housing and an antenna system formed by the same. The wideband wave-transmitting metamaterial comprises a first base plate and a second base plate, a square ring structure is sandwiched between the first base plate and the second base plate, and square patches are arranged on the external surface of the first base plate and the external surface of the second base plate in array form. The wideband wave-transmitting metamaterial and the antenna housing provided by the invention both have very high wave-transmitting efficiency in the wideband of 6-18GHz, and smaller loss.

Description

technical field [0001] The present invention relates to wave-transparent materials, more specifically, to broadband wave-transparent metamaterials, radome and antenna system thereof. 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 in the interior of the substrate. The substrate can be virtually divided into multiple substrate units arranged in a rectangular array. Each substrate unit is attached with artificial microstructures to form a metamaterial unit. The entire metamaterial is composed of many such metamaterial units, just like Crystals are composed of countless crystal lattices arranged in a certain way. The artificial microstructures on each metamaterial unit may or may not be identical. Artificial microstructures are planar or three-dimensional...
