Abstract

The invention relates to a broadband wave-transmitting material, as well as an antenna housing and an antenna system thereof. The broadband wave-transmitting material is used for realizing broadband wave transmitting, and comprises multiple layers of substrates and a plurality of first artificial microstructures; the substrates are made of nonmetallic materials; each first artificial microstructure is clamped between any two adjacent substrates and arrayed; the wave-transmitting material further comprises second artificial microstructures adhered to the outer surfaces of the two outermost layers of substrates in the multiple layers of substrates; the second artificial microstructures are different from the first artificial microstructures. The broadband wave-transmitting material, the antenna housing and the antenna system are very high in wave-transmitting efficiency within the range of 2-18 GHz broad band. After the antenna housing is added on the antenna, the radiating capacity of the antenna is enhanced, and the gain is improved effectively.

Description

technical field [0001] The present invention relates to radomes, and more particularly, to broadband wave-transmitting materials, radomes and antenna systems thereof. Background technique [0002] Generally, an antenna system is provided with a radome. The purpose of the radome is to protect the antenna system from wind, rain, ice, snow, sand and solar radiation, etc., so that the performance of the antenna system is relatively stable and reliable. At the same time, the wear, corrosion and aging of the antenna system are reduced, and the service life is prolonged. However, the radome is an obstacle in front of the antenna, which will absorb and reflect the radiation 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, materials for making radomes are mostly made of materials with low dielectric constant and loss tangent, and high mechanical strength, su...
