The invention relates to a low-frequency wave-transmitting material, its radome and an antenna system. The low-frequency wave-transmitting material includes a first substrate, a second substrate, and a third substrate with different thicknesses, and is interposed between the first substrate and the second substrate. The first artificial microstructure arranged in an array, the second artificial microstructure arranged in an array between the second substrate and the third substrate, wherein the first artificial microstructure is a metal ring, and the second artificial microstructure is Multiple metal rings with a common center. The low-frequency wave-transmitting material and its radome and antenna system of the present invention have high wave-transmitting efficiency in the low-frequency band, and can shield other frequency bands.
Description
technical field [0001] The present invention relates to a radome, and more particularly to a low-frequency 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 an...
