Embodiment Construction

[0021] The invention provides a dual-band transparent wave material, which includes at least one first substrate made of non-metallic material and a plurality of artificial microstructures attached to the first substrate and arranged in an array. There are many options for manufacturing substrate materials, such as ceramics, FR4, F4B (polytetrafluoroethylene), HDPE (High Density Polyethylene), ABS (Acrylonitrile Butadiene Styrene), ferroelectric materials, or ferromagnetic materials, etc. .

[0022] Such as figure 1 As shown, the dual-band transparent wave material in this embodiment includes two substrates, that is, a first substrate 10 and a second substrate 20 made of non-metallic materials, and a substrate sandwiched between the first substrate 10 and the second substrate 20. A plurality of artificial microstructures 30 arranged in an array between them.

[0023] The artificial microstructure 30 is a planar structure with a certain geometric pattern composed of wires mad...

Abstract

The invention relates to a dual-frequency band-pass wave-transmitting material, an antenna housing made of the dual-frequency band-pass wave-transmitting material and an antenna system comprising the antenna housing. The dual-frequency band-pass wave-transmitting material comprises at least one first substrate and a plurality of artificial microstructures, the first substrates are made of nonmetal materials, the artificial microstructures are attached on the first substrates and are arrayed, each artificial microstructure comprises a crossed structure and a square structure intersected with the crossed structure, and notches are arranged at four end corners of each square structure. The antenna housing made of the dual-frequency band-pass wave-transmitting material can work in two frequency bands, wave transmitting efficiency in each two corresponding frequency bands is high, other frequency bands can be shielded, accordingly, interference is eliminated, and a good working environment for the antenna is guaranteed. Besides, the radiating capacity of an antenna is strengthened after the antenna housing is arranged on the antenna, and gain is effectively increased.

Description

technical field [0001] The present invention relates to a radome, and more particularly, to a dual-band transparent wave 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. [0003] At present, the materials for making radome are mostly materials with low dielectric constant and loss tangent and high mechanical strength, such as fiberglass, e...
