High-wave-transmission metamaterial, antenna housing made of high-wave-transmission metamaterial and antenna system comprising antenna housing

Abstract

The invention relates to a high-wave-transmission metamaterial, an antenna housing made of the high-wave-transmission metamaterial and an antenna system comprising the antenna housing. The high-wave-transmission metamaterial comprises at least one metamaterial sheet layer, each metamaterial sheet layer comprises a first substrate, a second substrate and a plurality of artificial microstructures which are clamped between the first substrate and the second substrate and are arrayed, each artificial microstructure comprises a square structure and four right-angled bent portions, the four right-angled bent portions of each artificial microstructure are arranged inside the square structure of the artificial microstructure and respectively enclose with four end corners of the square structure to form square structure units, the right-angled bent portions of each artificial microstructure are not overlapped mutually, and notches with identical sizes are respectively arranged at the four end corners of each square structure. The high-wave-transmission metamaterial has the advantages that wave transmission efficiency within the frequency range of 5-6GHz is high, and loss is low. In addition, the radiating capacity of an antenna is strengthened after the antenna housing is arranged on the antenna, and gain is effectively increased.

Description

technical field [0001] The present invention relates to a radome, and more particularly, to a highly transparent metamaterial, a radome and an 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 structures with...
