Embodiment Construction

[0024] The present invention provides a metamaterial radome, comprising at least one metamaterial sheet 1, such as figure 1 and figure 2 shown. Each metamaterial sheet 1 includes two opposite substrates and an array of artificial microstructures attached between the two substrates. When there are multiple metamaterial sheets 1, each metamaterial sheet 1 is superimposed along the direction perpendicular to the sheets, and assembled into a whole by mechanical connection, welding or bonding, such as figure 2 shown.

[0025] image 3 A schematic diagram of the disassembled structure of a metamaterial sheet is shown. Including at least one metamaterial sheet 1, each metamaterial sheet 1 includes two identical uniform and equal-thick sheet substrates: a first substrate 10 and a second substrate 20 that are oppositely arranged, and the first substrate 10 faces the second substrate. Artificial microstructures 30 arranged in an array are attached to the surface of the substrate ...

Abstract

The invention relates to a metamaterial antenna housing. The metamaterial antenna housing comprises metamaterial sheet layers, wherein each metamaterial sheet layer comprises a first substrate and a second substrate, each first substrate and each second substrate are arranged in an opposite mode, a plurality of artificial microstructures which are arranged in an array mode are arranged between each first substrate and each second substrate in a clamped mode, each artificial microstructure comprises a first metal wire and a second metal wire, each first metal wire and each second metal wire are L-shaped, an image formed by each first metal wire after each first metal wire rotates around the right-angle vertex of itself by 180 degrees is the same as an image formed by the second metal wire, and a closed rectangle is formed by each first metal wire and each second metal wire in a mutual-splicing mode. Needed electromagnetic response is obtained by the metamaterial antenna housing by attaching the artificial microstructures with specific shapes to the substrates, wave-transparent performance of the antenna housing is improved, and capacity of resisting disturbance of the antenna housing based on a metamaterial is improved, and the frequency band reaches more than 5G.

Description

technical field [0001] The present invention relates to radome, and more particularly, to a metamaterial radome. Background technique [0002] Metamaterials, commonly known as metamaterials, are a new type of synthetic material, which is composed of a substrate made of non-metallic materials and multiple artificial microstructures attached to the surface of the substrate or embedded in the interior of the substrate. The substrate can be virtually divided into multiple substrate units arranged in a rectangular array. Each substrate unit is attached with artificial microstructures to form a metamaterial unit. The entire metamaterial is composed of many such metamaterial units, just like Crystals are composed of countless crystal lattices arranged in a certain way. The artificial microstructures on each metamaterial unit may or may not be identical. Artificial microstructures are planar or three-dimensional structures with certain geometric figures composed of metal wires, su...
