Embodiment Construction

[0024] The invention provides a ceramic-based wave-transparent material, such as figure 1 As shown, it includes two layers of first ceramic substrates 1, a plurality of metal microstructures 30 arranged in a grid between the two layers of first ceramic substrates 1, and covering the two layers of first ceramic substrates 1 respectively. The outer surface of the two-layer second ceramic substrate 2, and the second ceramic substrate 2 is different from the first ceramic substrate 1. A plurality of metal microstructures 30 constitute the metal layer 3 . 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 oxid...

Abstract

The invention relates to a ceramic-based wave-transmitting material as well as an antenna cover and an antenna system thereof. The ceramic-based wave-transmitting material comprises two layers of first ceramic substrates, a plurality of metal microstructures which are arranged between the two layers of first ceramic substrates in a clamped manner and distributed in a grid shape, and two layers of second ceramic substrates which are used for covering the outer surfaces of the two layers of first ceramic substrates respectively and are different from the first ceramic substrates. The wave-transmitting material made of different ceramic substrates as well as the antenna cover and the antenna system of the wave-transmitting material are very high in wave-transmitting efficiency within wider frequency band. After the antenna cover is added to an antenna, the radiation capability of the antenna is improved and the gain is effectively increased.

Description

technical field [0001] The present invention relates to wave-transmitting technology, and more specifically, relates to a ceramic-based wave-transmitting 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 stre...
