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 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 incident electromagnetic wave. Transmission, improve the directionality of electromagnetic wave radiation, and increase the gain of the antenna.

Abstract

The invention relates to a meta-material microwave antenna housing and an antenna system. The meta-material microwave antenna housing is covered on the antenna and comprises at least one meta-material sheet layer, wherein each meta-material sheet layer comprises a substrate and a plurality of manmade micro structures which are arranged on two opposite surfaces of the substrate in an arrayed manner; the substrate is divided into a plurality of meta-material units, wherein two opposite surfaces of each meta-material unit are respectively provided with a manmade micro structure, and manmade micro structures are the same in the dimension; and the manmade micro structure comprises a square-shaped structure which is firmly close to the edge of the meta-material unit and a square patch which is arranged on the centre of the meta-material unit. With the adoption of the meta-material microwave antenna housing and the antenna system, the manmade micro structure with a special shape is attached on the substrate, and the relative dielectric constant, refractive index and impedance of the material are changed by regulating the shape and dimension of the manmade micro structure, transmission of electromagnetic wave is reinforced, and directivity and gain of the antenna is improved.

Description

technical field [0001] The present invention relates to radomes, and more particularly, to metamaterial microwave 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 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 certain geometric figur...
