Embodiment Construction

[0041] Such as Figure 4 as shown, Figure 4It is a schematic diagram of the three-dimensional structure of the basic unit constituting the metamaterial. The basic unit of a metamaterial includes an artificial microstructure 1 and a substrate 2 to which the artificial microstructure is attached. In the present invention, the artificial microstructure is an artificial metal microstructure, and the artificial metal microstructure has a planar or three-dimensional topological structure that can respond to the electric field and / or magnetic field of the incident electromagnetic wave, and changes the performance of the artificial metal microstructure on each metamaterial basic unit. The pattern and / or size can change the response of each metamaterial elementary unit to incident electromagnetic waves. Multiple basic units of metamaterials can be arranged according to certain rules to make metamaterials have a macroscopic response to electromagnetic waves. Since the overall metama...

Abstract

The invention relates to a metamaterial antenna which comprises a shell, a feed source, first metamaterial, second metamaterial and third metamaterial, wherein the first metamaterial is closely attached on the bore edge of the feed source, a preset distance is arranged between the first metamaterial and the second metamaterial, the first metamaterial and the second metamaterial are arranged oppositely, and the third metamaterial is closely attached to the edge of the second metamaterial. The shell, the feed source, the first metamaterial, the second metamaterial, and the third metamaterial form a closed cavity. The central axis of the feed source penetrates through the central point of the first metamaterial and the central point of the second metamaterial. One surface of the first metamatieral and one surface of the second metamaterial are arranged outside the cavity, and provided with reflective layers used for reflecting electromagnetic waves. The central area of the second metamaterial is a through hole. The metamaterial antenna utilizes the unique electromagnetic property of metamaterial to improve the aperture efficiency of the antenna and obtain a good far field radiation field response through multiple reflections of the electromagnetic waves. Meanwhile, the design of the multiple reflections greatly reduces the thickness of the antenna and enables an antenna system to reach miniaturization.

Description

technical field [0001] The invention relates to the field of antennas, and more specifically, to a metamaterial antenna. Background technique [0002] "Metamaterial" refers to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, the limitation of some apparent natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary nature inherent in nature. [0003] The refractive index distribution inside the metamaterial is the key part for the metamaterial to exhibit extraordinary functions, and different refractive index distributions correspond to different functions. The more precise the refractive index profile, the better the function achieved. For conventional antennas, especially horn antennas, the aperture efficiency has a great influence on the improvement of an...
