Abstract

The invention discloses an overlapping antenna unfolding support, which comprises a body, a fixing frame, a regulator, a flange plate and an unfolding frame, wherein the flange plate is of a solid cubic structure; the two symmetrical side surfaces of the flange plate are respectively provided with fixing frames used for installing the antenna; each of the fixed frames is provided with a regulatorused for regulating the omni-directional freedom degree of the antenna; the other two symmetrical side surfaces of the flange plate are respectively provided with the body used for supporting the antenna and the unfolding frame used for lifting the antenna and unloading an antenna reflector through zero gravity; the side face of the flange plate, which is not provided with the body, the fixing frame and the unfolding frame, is provided with a through hole used for assembling a satellite; and the edge of the through hole is provided with a flange used for containing the antenna. According to the unfolding support in the invention, the body, the fixing frame, the regulator, the flange plate and the unfolding frame are matched so that reliable fine adjustment of the omni-directional degree offreedom of the reflection surface of the antenna is realized, and the defects of a traditional satellite antenna unfolding support are overcome.

Description

technical field [0001] The invention relates to an overlapping antenna unfolding support, which is especially suitable for Ka frequency band user link antennas, and belongs to the technical field of antenna unfolding and retracting support structures. Background technique [0002] The satellite antenna subsystem includes Ka-band user link antennas (4 antennas in total), 1 Ka-band transmit and receive shared feeder link antenna, and 1 Ka-band beacon antenna, a total of 6 antennas; among them, the Ka-band user link antenna adopts 4-caliber multi-beam antenna technology, composed of 4 antennas: East Antenna South, East Antenna North, West Antenna South, and West Antenna North. [0003] According to the technical process of satellite prototype development, the antenna subsystem needs to be tested in a compact field state and payload test on the satellite platform. During the test period, the Ka user link antennas on the east and west boards of the satellite (a total of 4 deploy...
