Embodiment Construction

[0027] 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 wide-band high-wave transmission metamaterial, an antenna housing thereof and an antenna system. The wide-band high-wave transmission metamaterial comprises at least one metamaterial sheet layer, wherein each metamaterial sheet layer comprises a first substrate and plurality of artificial microstructures, the artificial microstructures are distributed on the first substrate in an array way and in a structure shaped like a Chinese character 'tian', and the center position of the structure shaped like the Chinese character 'tian' is provided with a notch. In the invention, needed electromagnetic response is obtained by adhering the artificial microstructures with specific shapes on the first substrate, and therefore, the wave transmission performance of the antenna housing based on the wide-band high-wave transmission metamaterial is enhanced and the antijamming capability is increased; the wide-band high-wave transmission metamaterial, the antenna housing thereof and the antenna system have the advantages of wider working frequency band, very high wave transmission efficiency and less loss; and the requirements for high frequency, wide band and high wave transmission are met.

Description

technical field [0001] The present invention relates to a wave-transparent material, more specifically, to a broadband high-wave-transparency 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 thre...
