Abstract

The invention relates to a radome material and a radome and an antenna system adopting the same. The radome material comprises a first substrate, a second substrate, a plurality of first metal microstructures, a plurality of second metal microstructures and a plurality of third metal microstructures, wherein the first substrate and the second substrate are made of non-metallic materials; the plurality of first metal microstructures are sandwiched between the first substrate and the second substrate and are arranged into a mesh shape; a plurality of second metal microstructures are attached to the outer surface of the first substrate; a plurality of third metal microstructures are attached to the outer surface of the second substrate; and the second metal microstructures, the third metal microstructures and the first metal microstructures are different. The radome material and the radome and the antenna system which adopt the same have high wave transmitting efficiencies in a Ku wave band and other frequency bands can be shielded, so that the interference is eliminated and the excellent working environment of an antenna is ensured. After the radome is added on the antenna, the radiating capacity of the antenna is strengthened and the gain is effectively improved.

Description

technical field [0001] The present invention relates to a radome, and more particularly, to a wave-transparent material and a radome and antenna system thereof. Background technique [0002] Generally, the antenna system is provided with a radome. The purpose of the radome is to protect the antenna system from wind, rain, snow, sand 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. However, the radome is an obstacle in front of the antenna, which will absorb and reflect the radiated waves of the antenna, change the free space energy distribution of the antenna, and affect the electrical performance of the antenna to a certain extent. [0003] At present, the materials for making radome are mostly materials with low dielectric constant and loss tangent and high mechanical strength, such as fiberglass, epoxy resin...
