Embodiment Construction

[0021] The invention provides a dual-frequency band-pass low-pass wave-transparent material, such as figure 1 As shown, it includes a first substrate 10 and a second substrate 20 made of non-metallic materials, and a plurality of metal microstructures 30 sandwiched between the first substrate 10 and the second substrate 20 and arranged in an array. The metal microstructure 30 is a square patch, and there is a preset distance between adjacent square patches. A plurality of metal microstructures 30 constitute the first metal layer A. As shown in FIG. The metal microstructure 30 is a planar structure made of conductive material with a certain geometric pattern. The conductive material here can be metal materials with good electrical conductivity such as gold, silver, and copper, or an alloy material whose main component is one or two of gold, silver, and copper, or carbon nanotubes, aluminum-doped oxides, etc. Conductive non-metallic materials such as zinc and indium tin oxide....

Abstract

The invention relates to a low pass wave-transmitting material and an antenna housing and an antenna system of the low pass wave-transmitting material. The low pass wave-transmitting material comprises a first base plate, a second base plate, and a plurality of metal microstructures which are sandwiched between the first base plate and the second base plate and arranged in an array way; the first base plate and the second base plate are made from a non-metallic material, the metal microstructures are square patches; and distances are preset between the adjacent square patches at intervals. The low pass wave-transmitting material and the antenna housing and antenna system thereof provided by the invention are high in wave-transmitting efficiency at low frequency band, and can shield high frequency band, thereby removing disturbance and ensuring good working environment of an antenna; and moreover, a high frequency signal can be inhibited under the condition of realizing low frequency wave-transmitting, so as to realize a stealth function.

Description

technical field [0001] The present invention relates to wave-transparent technology, more specifically, to low-pass wave-transparent material and its radome and antenna system. 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 fibergl...
