Example Embodiment

[0025] Metamaterials are artificial composite structural materials with supernormal physical properties that natural materials do not have. The orderly arrangement of microstructures can change the relative permittivity and magnetic permeability of each point in space. Metamaterials can achieve refractive index, impedance, and wave transmission performance that ordinary materials cannot have within a certain range, thereby effectively controlling the propagation characteristics of electromagnetic waves. The metamaterial radome based on artificial microstructures 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 air to maximize the incident electromagnetic wave. transmission. The frequency can be selected by adjusting the size of the microstructure, and the corresponding transmission and filtering frequencies can be adjusted according to n...

Abstract

The invention relates to a low-loss metamaterial antenna housing which comprises at least one metamaterial piece layer. Each metamaterial piece layer comprises a first substrate and a plurality of man-made micro-structures with the same size, wherein the man-made micro-structures are distributed on each first substrate in an array mode. The man-made micro-structures are of cross-shaped structures. Due to the fact that the man-made micro-structures in specific shapes are attached to the substrates, required electromagnetic response is obtained, the wave-transparent performance of the antenna housing based on the metamaterial is strengthened, and anti-jamming capability is improved. Meanwhile, the loss of the antenna housing nearby the frequency point range of 30GHz is quite low, and wave-transparent efficiency is quite high.

Description

technical field [0001] The present invention relates to radomes, and more particularly, to low loss 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 ...
