A kind of metamaterial, antenna device and radome

Abstract

The present invention relates to a metamaterial, the metamaterial comprises a substrate, and is arranged on the substrate, uniformly covers the substrate, and is arranged in the same direction, allowing electromagnetic waves with a specific polarization direction to pass through the substrate and transported metal microstructure unit; the metal microstructure unit includes a metal microstructure whose structural size is smaller than the unit size; all the metal microstructure units on the substrate are sequentially adjacent on four sides and arranged in the same direction. The invention also relates to an antenna device and a radome using the above-mentioned material. The metamaterial, antenna device and radome implementing the present invention have the following beneficial effects: the electromagnetic wave passage function for selecting a specific polarization direction has the advantages of relatively simple structure, no more restrictive conditions, and lower cost.

Description

technical field [0001] The invention relates to the field of communication, more specifically, to a metamaterial, an antenna device and a radome. Background technique [0002] In the field of communication, it is often necessary to perform polarization-selective reception on the electromagnetic wave signals transmitted and received during the communication process, that is, only the linear polarization in the design direction is received, and the signals orthogonal to the design polarization direction are greatly reflected, so as to Improve the performance of the receiver in the communication system, so that it can better receive the electromagnetic signal it needs in the complex electromagnetic environment. Since ordinary dielectric materials are isotropic and cannot be changed by design, ordinary dielectric materials cannot be used to achieve the above functions. In fact, in the prior art, the electromagnetic waves with the same polarity are usually received by increasing...
