Embodiment Construction

[0026] 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 broadband metamaterial antenna housing and an antenna system. The metamaterial antenna housing works in the Ku wave band. The broadband 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 which are arranged on the first substrate in an array mode, and the sizes of the artificial microstructures are the same. Each artificial microstructure comprises a snowflake-shaped structure, and each snowflake-shaped structure comprises a cross-shaped structure and four straight-line-shaped structures which are same in size and arranged on four end points of the cross-shaped structure respectively. According to the broadband metamaterial antenna housing, the artificial microstructures in specific shapes are attached to the first substrates to obtain needed electromagnetic responses, wave-transparent performance of the antenna housing based on metamaterials is strengthened, and anti-interference capacity is increased. The working band of the antenna housing is the Ku wave band (12-18GHz), wave-transparent efficiency within the band is high, and losses are fewer. Furthermore, the working band of the antenna housing still has good wave-transparent performance when an electromagnetic wave band incomes in a certain angle.

Description

technical field [0001] The present invention relates to a radome, and more particularly, to a broadband metamaterial radome and an antenna system. 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 f...
