New-type light metamaterial and antenna housing

Abstract

The invention relates to a new-type light metamaterial and an antenna housing. The material comprises at least one material sheet, each material sheet comprises at least one dielectric substrate and an artificial metal microstructure arranged on the dielectric substrate. The dielectric substrate is composed of a polymer-based composite material or a foam material. The polymer-based composite material comprises a basal body and reinforced materials combined with the basal body. As the dielectric substrate is made of the polymer-based composite material or the foam material, various materials compensate with each other in the performance to generate synergistic effect; the combination performance of the materials is superior to the original ingredients so as to meet different requirements and fully display respective advantages; besides, the total weight is light and good structural design is realized.

Description

technical field [0001] The invention relates to a material and a radome, more specifically, to a novel lightweight supermaterial and a radome. Background technique [0002] The radome is used to protect the antenna system from the influence of wind, rain, snow, sand and solar radiation, etc., so that the performance of the antenna system is relatively stable and reliable, while reducing the wear, corrosion and aging of the antenna system and prolonging the service life. For high-speed flying aircraft, the radome can also solve the problems caused by high temperature, aerodynamic load and other loads on the antenna. [0003] At present, the materials for preparing radome are mostly materials with low dielectric constant and loss tangent, but high mechanical strength, such as fiberglass, epoxy resin, high molecular polymer, etc., and the structure is mostly uniform single-wall structure, sandwich structure and space. skeleton structure etc. In the radome made of the above-me...

AI Technical Summary

Problems solved by technology

In the radome made of the above-mentioned existing materials, because the design of the thickness of the cover wall needs to take into account factors such as the working wavelength, the size and shape of the radome, the environmental conditions, the electrical and structural performance of the materials used, etc., in ensuring the antenna mechanical In terms of strength, the weight is often heavy, so it is not suitable for applications such as aircrafts that require light weight
