High-gain antenna housing and antenna system

Abstract

The invention relates to a high-gain antenna housing and an antenna system. The high-gain antenna housing is arranged on the antenna and comprises a metamaterial panel, wherein a radiation source of the antenna is arranged oppositely to the metamaterial panel; a connection line between an equivalent point of the radiation source of the antenna and the centre of the metamaterial panel is vertical to the metamaterial panel; the metamaterial panel is divided into a plurality of tightly-attached concentric ring bodies of which the side surfaces are curved surfaces; the radius of the bottom surface of each ring body is smaller than that of the top surface; an electromagnetic wave is emitted in parallel from the top surface of each ring body after passing through the metamaterial panel; an included angle between the connection line of the radiation source and a point on the bottom surface of the i-th ring body and the connection line vertical to the metamaterial panel is set to be theta; the included angle theta solely corresponds to the curved surface inside the i-th ring body; and the refractive index of each part of the curved surface solely corresponding to the included angle theta is equal, and the refractive index of each ring body is gradually reduced along with he increase of the included angle theta. The antenna housing disclosed by the invention facilitates the receiving antenna to receive signals as much as possible and improves the signal strength and gain.

Description

technical field [0001] The present invention relates to the field of electromagnetism, and more particularly, to high gain radomes and antenna systems. 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 geomet...
