Metamaterial base station antenna housing and antenna system

Abstract

The invention relates to a metamaterial base station antenna housing and an antenna system. The metamaterial base station antenna housing is covered on an antenna and comprises at least one metamaterial sheet layer, wherein each of the metamaterial sheet layer comprises a substrate and a plurality of artificial microstructures arranged on the substrate in an array; the substrate can be divided into a plurality of metamaterial units, and each of the metamaterial units is configured with one artificial microstructure; each of the artificial microstructure comprises a cross-shaped structure arranged at the center of the metamaterial unit and four circular ring structures arranged in four quadrants divided by the cross-shaped structure respectively. According to the invention, the artificial microstructures with special shapes are adhered to the substrate, the relative dielectric constant, the refractive index and the impedance of the material are changed through adjusting the shape and the size of the artificial microstructures, thereby reinforcing transmission of electromagnetic waves, and improving the directivity and the gain of the antenna.

Description

technical field [0001] The present invention relates to radomes, and more particularly, to metamaterial base station 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 l...

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
