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. And the frequency can be selected by adjusting the size of the microstructure, and the corresponding wave-transmitting and filtering...

Abstract

The invention relates to a high-wave transmission metamaterial antenna housing and an antenna system, wherein the high-wave transmission metamaterial antenna housing is covered on the antenna. The metamaterial antenna housing comprises at least one metamaterial sheet layer, wherein each metamaterial sheet layer comprises a first substrate and a plurality of artificial microstructures with the same dimension arranged on the first substrate in an array; the artificial microstructure comprises a snowflake-shaped structure, and the snowflake-shaped structure comprises a cross-shaped structure and four I-shaped structures with the same dimension arranged at four endpoints of the cross-shaped structure respectively; and the first substrate can be divided into a plurality of metamaterial units, and each of the metamaterial units is configured with one artificial microstructure. According to the invention, the artificial microstructures with special shapes are adhered on the substrate to obtain the necessary electromagnetic response so as to reinforce the wave transmission performance of the metamaterial based antenna housing, and the reflection loss is very small; and the equivalent impedance of the antenna is close to 1, and impedance matching with the air is well realized.

Description

technical field [0001] The invention relates to a radome, and more specifically, to a radome and an antenna system of a high-transparency metamaterial. 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 geomet...
