Embodiment Construction

[0023] like figure 1 As shown, the metamaterial radome 10 of the present invention includes a hollow rigid frame 20 and a metamaterial plate 30 that can be fixed on the surface of the frame 20, figure 1 Shown in is two metamaterial sheets 30 that can be respectively fixed to two opposite sides of the frame 20 . The frame 20 is made of any existing material such as fiberglass, and includes a substantially U-shaped frame body 22 and elongated guide grooves 24 disposed at two extending ends of the frame body 22 . A concave groove 222 is respectively formed on both sides of the periphery of the frame body 22 . The guiding groove portion 24 forms a guiding groove 242 .

[0024] like figure 2 and image 3 As shown, each metamaterial sheet 30 includes at least one metamaterial sheet 40 . Each metamaterial sheet 40 includes two dielectric substrates 42 , 44 bonded together and a structural layer 46 placed between the two dielectric substrates 42 , 44 and covered by the two diele...

Abstract

The invention relates to a metamaterial antenna housing which comprises a rigid frame and a metamaterial board. The metamaterial board is fixed on the surface of the frame, and is provided with a plurality of metal microstructures, and a cavity used for containing an antenna is formed. Due to the fact that the frame is good in rigidity, the metamaterial antenna housing has good mechanical performance. Due to the fact that the metamaterial board which covers the frame is provided with the metal microstructures, loss of electromagnetic waves is low, and the metamaterial antenna housing has good wave transmission performance.

Description

technical field [0001] The present invention relates to a radome, and more particularly, to a metamaterial radome. Background technique [0002] In the antenna system, a radome is often used to protect the antenna from the harsh external environment, which not only prolongs the service life of the antenna, but also makes the antenna more concealed. Generally, this kind of radome is made of wave-transparent materials, such as high-molecular polymers such as fiberglass, epoxy resin, ABS, and UPVC with low dielectric constant and loss tangent and high mechanical strength, so that the radome has good Wave transparency and mechanical properties. However, with the emergence of new application requirements, the radome made of existing materials can no longer meet people's requirements for the antenna's mechanical properties and high transmittance. [0003] Metamaterials are artificial composite structures with extraordinary physical properties that are not found in natural materi...
