Abstract

The invention relates to a dual-passband wave-transmitting material, a radome and an antenna system. The dual-passband wave-transmitting material comprises a first substrate and a second substrate which are made of non-metal materials, and a plurality of first metal micro-structures clamped between the first substrate and the second substrate and arranged in a latticed manner, wherein no gap is reserved between the adjacent first metal micro-structures; and the first metal micro-structures adopt cross-shaped structures. The invention also provided a radome and an antenna system. The dual-passband wave-transmitting material, the radome and the antenna system, provided by the invention, can work in two frequency bands, have high wave-transmitting efficiency in the two frequency bands, and can shield other frequency bands, thereby eliminating interference and ensuring favorable work environments of the antenna. After the antenna is equipped with the radome, the radiating capacity of the antenna is enhanced and the gain is effectively improved.

Description

technical field [0001] The present invention relates to a radome, more specifically, to a double-passband wave-transparent material, a radome and an 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,...
