Abstract

The invention discloses a high-gain horn antenna based on metamaterial loading, which includes a standard horn antenna, a metamaterial plate, and four screws for positioning and fixing the metamaterial plate. Four kinds of metamaterial structural units are arranged in parallel and close to each other. When loaded on the output port surface of a standard horn antenna, the electromagnetic wave amplitude and phase distribution of the horn antenna can be adjusted to achieve high-gain radiation. The invention can be used in microwave and millimeter wave communication and radar antenna feeder systems, and has the advantages of being suitable for miniaturization, light weight, integration, and low cost of antenna feeder systems, and its processing cycle is short, and various radiation properties can be replaced by It can be easily realized by a metamaterial slab arranged with different structural units.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave antennas, and relates to a high-gain horn antenna. Background technique [0002] The horn antenna is a commonly used antenna form in modern communication and radar systems. Because of its high power capacity and low loss, it is especially suitable for high-power and extremely high-frequency systems. However, with the rapid development of modern communication and radar systems, the electrical performance requirements of microwave and millimeter wave antennas are getting higher and higher, and at the same time, they are also developing in the direction of miniaturization, light weight, integration, and low cost. Therefore, the horn antenna Improved design remains a hot topic in science as well as industry. [0003] In order to improve the radiation gain of the horn antenna and realize the long-distance work of the system, Yang Rui and others disclosed a high-gain ultra-wideban...
