Embodiment Construction

[0024] Metamaterials are artificial composite structural materials with supernormal physical properties that natural materials do not possess. 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 properties 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 incidence of electromagnetic waves. transmission. The frequency can be selected by adjusting the size of the microstructure, and the corresponding transmission and filtering frequencies can be adjusted accordi...

Abstract

The invention relates to a super-material antenna housing with a filtering function. The super-material antenna housing comprises at least one super-material sheet layer, wherein each super-material sheet layer comprises a first substrate and a plurality of artificial micro-structures which are arranged on the first substrate in an array mode; each artificial micro-structure comprises a square-shaped structure and a cross-shaped structure; the four corners of the square-shaped structure are respectively provided with a notch; a U-shaped structure of which the opening faces outwards is arranged at each notch; and four terminal points of the cross-shaped structure are overlapped with the middle points of four sides of the square-shaped structure. The antenna housing provided by the invention satisfies good wave penetrating performance and has the filtering function; in addition, the working frequency band of the antenna housing ranges from 6.82 GHz to 17.53 GHz and the bandwidth of the antenna housing is more than 10 GHz; and furthermore, the antenna housing is very high in wave penetrating efficiency within the frequency band and has band stop characteristic nearby 5 GHz and 22.5 GHz, so that the antenna housing can realize selective filtering.

Description

Technical field [0001] The present invention relates to a radome, and more specifically, to a metamaterial radome with filtering function. Background technique [0002] Metamaterials, commonly known as metamaterials, are a new type of artificial 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 substrate. The substrate can be virtually divided into a plurality of substrate units arranged in a rectangular array, and each substrate unit is attached with artificial microstructures to form a metamaterial unit. The entire metamaterial is composed of many such metamaterial units, like Crystals are composed of countless lattices in a certain arrangement. The artificial microstructures on each metamaterial unit may be the same or not exactly the same. Artificial microstructure is a plane or three-dimensional structure with a certain geometric figure comp...
