Abstract

The invention relates to a broadband wave-transparent material as well as an antenna cover and an antenna system thereof. The broadband wave-transparent material comprises at least one first substrate made of a non-metal material and a plurality of artificial microstructures which are attached to the first substrate and distributed in an arraying manner; each artificial microstructure comprises a circular structure with two symmetrical openings and a straight structure passing through the center of the circular structure, and the two symmetrical openings are respectively positioned at two sides of the straight structure. The broadband wave-transparent material as well as the antenna cover and the antenna system thereof can work in a wider frequency band and are high in wave-transparent efficiency and capable of shielding other frequency bands, thereby eliminating interference and ensuring a favorable working environment of an antenna. After the antenna cover is arranged on the antenna, the radiation capability of the antenna is enhanced and the gain is effectively increased.

Description

technical field [0001] The present invention relates to a radome, more specifically, to a broadband wave-transmitting 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. The reasons for these phenomena are: the reflection of the radome wall and the diffraction of the uneven part will cause the electrical axis of the main lobe of the antenna t...
