Abstract

The invention provides a multi-caliber movable unfolding antenna and belongs to the field of antenna technologies. The multi-caliber movable unfolding antenna comprises an unfolding back frame, an unfolding arm, a two-dimensional unfolding mechanism and multiple reflector components, wherein the multiple reflector components are fixed to different positions of the unfolding back frame, one end ofthe unfolding arm is connected with the unfolding back frame, the other end of the unfolding arm is connected with the two-dimensional unfolding mechanism, and the two-dimensional unfolding mechanismis used for driving the unfolding arm to rotate, so that all the reflector components fixed to the unfolding back frame realize azimuth and pitch rotation. According to the antenna, overall beam global coverage can be realized just by adjusting the rotating angle of the two-dimensional unfolding mechanism.

Description

technical field [0001] The invention relates to the technical field of antennas, and in particular provides a multi-aperture movable deployable antenna and a deploying method thereof. Background technique [0002] With the continuous development of aerospace technology and the rapid development of high-throughput satellites, higher requirements are put forward for multi-beam antennas, such as beam pointing flexibility, independent beam coverage areas, and overall beam global coverage. The existing technology cannot meet this demand, so there is an urgent need for a solid surface reflector with simple structure and multi-aperture movable deployment. Contents of the invention [0003] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a multi-aperture movable deployment antenna, which can realize the global coverage of the whole beam by adjusting the rotation angle of the two-dimensional deployment mechanism. [0004] Technica...
