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 comprises a metamaterial panel, wherein the metamaterial panel is divided into a plurality of areas; an electromagnetic wave enters the first surface of the metamaterial panel and is emitted from the second surface opposite to the first surface; an intersection part of the i-th area and the first surface is the bottom surface of the i-th area; the intersection part of the i-th area and the second surface is the top surface of the i-th area; an included angle between a connection line of a radiation source and a point on the bottom surface of the i-th area and the connection line vertical to the metamaterial panel is theta; the included angle theta solely corresponds to a curved surface within the i-th area; a set of the points with the same included angle theta on the bottom surface of the ith area forms a boundary of the curved surface solely corresponding to the included angle theta; the refractive index of each part of the curved surface solely corresponding to the included angle theta is equal; and a bus of the curved surface is in an elliptic arc, and the refractive index of each area is gradually reduced along with the 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...
