Abstract

The invention provides a reflection array antenna beam scanning antenna based on a rotation phase shift surface technology. The reflection array antenna beam scanning antenna comprises a feed source antenna (401) and a reflection array panel (301); the reflection array panel (301) comprises a partial wave beam micro-strip reflection array layer (101) and a high transmittance phase shift surface layer (201); the partial wave beam micro-strip reflection array layer (101) is a micro-strip reflection array panel capable of achieving feed source wave beam deflection and the high transmittance phase shift surface layer (201) is a phase shift surface panel capable of achieving plane wave beam deflection. The partial wave beam micro-strip reflection array layer (101) and the high transmittance phase shift surface layer (201) are stacked through certain air space so that the reflection array panel (301) can be assembled. The positive feeding type is adopted by a feed source antenna (401). The central axis of the reflection array panel (301) serves as an axis and two layers are rotated respectively so that scanning of antenna beams can be achieved. The reflection array antenna beam scanning antenna based on the rotation phase shift surface technology is simple in structure, easy to manufacture, capable of responding to any polarized electromagnetic wave, suitable for sending and receiving the polarized electromagnetic waves and capable of bearing high power.

Description

technical field [0001] The invention relates to the communication field, and provides a reflective array beam scanning antenna based on the rotating phase shifting surface technology. Background technique [0002] Metamaterials are artificial electromagnetic materials that have been developed rapidly in the past ten years and have a modulation effect on electromagnetic waves. This material is usually carved with a metal pattern composed of metal microstructure units on a commercial dielectric substrate. The metal microstructure units usually use rings. , circle, square, I-shaped structure, etc., the metal pattern formed by arranging these metal microstructures according to a certain period has a certain modulation effect on the electromagnetic waves acting on its surface. [0003] Traditional ground satellite receiving antennas usually use parabolic reflector antennas, but due to their high precision requirements, it is difficult to process curved surfaces. At the same time,...
