Embodiment Construction

[0024] 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 metamaterial antenna housing which comprises at least one metamaterial sheet layer. The metamaterial sheet layer comprises a first substrate and a second substrate, wherein the first substrate and the second substrate are arranged in an opposite mode, and a plurality of artificial microstructures which are arranged in an array mode are arranged between the first substrate and the second substrate in a clamped mode. Each artificial microstructure comprises a crossed structure and four U-shaped structures which are arranged in four areas of the crossed structure respectively, wherein the crossed structure is divided into the four areas. According to the metamaterial antenna housing, due to the fact that the artificial microstructures with specific shapes are attached to the substrates, needed electromagnetic response is obtained, the wave-transparent performance of the antenna housing based on the metamaterial can be improved, and capacity of resisting disturbance of the antenna housing is improved. Frequency selection can be carried out through adjustment of the sizes of the artificial microstructures, and the corresponding wave-transparent frequency and the corresponding wave filtering frequency can be adjusted as needed. Due to the facts that the metamaterial antenna housing has good wave filtering performance, and further has the wave filtering function, the requirements of wave filtering performance of an antenna are reduced to a large extent, and the cost of a filter used by the antenna is also reduced.

Description

technical field [0001] The present invention relates to radomes, and more particularly, to metamaterial radomes. 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 figures composed of metal wires, su...
