Abstract

he invention discloses a broadband reconfigurable reflective array antenna. The antenna comprises a polarization grid, an M*N reconfigurable reflection arrays, a polarization rotation surface, a micromotor, a motor control bus, a phase control panel, a feed source antenna and a support structure, wherein each reconfigurable reflection array comprises a polarization rotation surface and a micro motor, the polarization rotating surface is connected with a micro motor, the polarization grid is arranged at an upper part of the support structure, the support structure is used for fixing the polarization rotation surface, the micro motor, the phase control panel and the feed source antenna, the feed source antenna is located in the center of the M*N reconfigurable reflection arrays, a radiationport surface of the feed source antenna is flush with the polarization rotation surface, and the phase control board is connected with the micro motor through a motor control bus. The antenna is advantaged in that a problem of insufficient working bandwidth of a single-bit reconfigurable reflective array antenna in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a broadband reconfigurable reflector array antenna. Background technique [0002] Onboard antennas are an important part of satellite payloads. With the vigorous development of modern satellite communications, the electrical performance indicators of spaceborne antennas have become more and more stringent, and it is often necessary to make full use of the small antenna installation space to achieve high-gain beam scanning. [0003] At present, the main forms of spaceborne antennas are reflector antennas and phased array antennas. Because the traditional reflector antenna needs to shape the surface, the processing is difficult, the processing process is complicated, the volume is large, and the structure is heavy. The processing mold of the traditional reflector antenna cannot be reused, resulting in the development and production costs of the traditional reflector antenna. It ...
