High-gain metamaterial antenna housing and antenna system

Abstract

The invention relates to a high-gain metamaterial antenna housing and an antenna system. The metamaterial antenna housing comprises at least one metamaterial slice layer, each metamaterial slice layer comprises a substrate and a plurality of artificial microstructures arranged on the substrate in an array mode; the artificial microstructures comprise four square-shaped structures arranged in an array mode, wherein a corner, close to the center of each artificial microstructure, of each square-shaped structure is provided with a notch. Needed electromagnetic response is obtained through the artificial microstructures in specific shapes and attached to the substrate. The relative dielectric constant, the refractive index and impedance of materials can be changed through regulation of the shapes and dimensions of the artificial microstructures, and directionality and grain of antennas are improved; under the condition of reaching the same grain, the array number of the antennas can be greatly reduced, and the overall size of the antennas is reduced. The space between the antenna housing and the antennas is little, the overall thickness is small, the number of layers of the metamaterial is regulated to control the grain of the antennas, user experience is improved, and different requirements of different customers for the grain of the antennas are met.

Description

technical field [0001] The present invention relates to radomes, and more particularly, to high gain metamaterial radomes and antenna systems. Background technique [0002] In recent years, with the development of wireless communication technology, wireless local area networks have penetrated into various places. In order to connect various wireless networks in series in a low-cost and wireless manner, it is necessary to strengthen the deployment of backbone network base stations, usually with long-distance and point-to-point Formed in a way, it requires high directivity and high gain antenna. [0003] Under normal circumstances, the antenna system will be equipped with a radome. The purpose of the radome is to protect the antenna system from wind, rain, snow, dust and solar radiation, so that the performance of the antenna system is relatively stable and reliable. At the same time, it reduces the wear, corrosion and aging of the antenna system and prolongs its service life...

AI Technical Summary

Problems solved by technology

The structure is mostly uniform single-wall structure, sandwich structure and space skeleton structure, etc. The design of the cover wall thickness needs to take into account factors such as the working wavelength, the size and shape of the radome, environmental conditions, and the electrical and structural performance of the materials used. Under the condition that the antenna is protected from the external environment, most of them do not have the function of enhancing the directivity and gain of the antenna
