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.

[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. The first substrate 10 and the second substrate 20 are preferably selected from materials with a dielectric constant of 2.2-4....

Abstract

The invention relates to a double-frequency band-pass wave-transparent material, a radome made of the double-frequency band-pass wave-transparent material and an antenna system. The double-frequency band-pass wave-transparent material comprises a first substrate which is made of a nonmetallic material, and a plurality of artificial microstructures which are attached on the first substrate and are arranged in an array. Each artificial microstructure comprises a cross-shaped structure which is obliquely arranged at a preset angle, and in-line structures which are perpendicularly intersected with four branches of the cross-shaped structure. The double-frequency band-pass wave-transparent material, he radome made of the double-frequency band-pass wave-transparent material and the antenna system provided by the invention can work within two frequency bands, the wave-transparent efficiency within the two frequency bands is very high, other frequency bands can be shielded to eliminate interference and the working environment of an antenna is guaranteed to be good; and after the antenna is provided with the radome, the radiation capability of the antenna is improved and the gain is effectively improved.

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...
