Abstract

The invention discloses a bandpass filter metamaterial, an antenna cover and an antenna system, wherein the bandpass filter metamaterial comprises a plurality of functional layers. Each functional layer comprises a dielectric layer and a conductive geometric structure which is arranged on the dielectric layer, wherein the conductive geometric structure on the dielectric layer of at least one functional layer in the multiple functional layers is a conductive sheet, and the geometric structure on the dielectric layer of another functional layer is grid-shaped. The bandpass filter metamaterial, the antenna cover and the antenna system improve wave penetrating effect of the antenna cover.

Description

technical field [0001] The invention relates to the field of filter materials, in particular to a band-pass filter metamaterial, a radome and an antenna system. Background technique [0002] Generally, the antenna is provided with a radome for protecting the antenna from environmental influences such as wind, rain, ice and snow. The existing radome is basically a pure material radome, which only serves to protect the antenna, and the use of a pure material radome will affect the performance of the antenna within a certain range. Among them, the pure material used to make the radome is an ordinary physical material. When making the pure material radome, using the half-wavelength or quarter-wavelength theory, when the thickness of the radome is half of the electromagnetic wave wavelength of the antenna working frequency band, The antenna has the best electromagnetic wave penetration. According to different antenna frequencies, the thickness of the pure material is changed to...
