Abstract

The embodiment of the invention provides a deployable rigid reflector antenna. The antenna comprises a support base assembly 1, a central fixing panel assembly 2 and a deployable panel assembly 3. Thesupport base assembly 1 and the central fixing panel assembly 2 are fixedly connected. The support base assembly 1 is fixedly connected with the deployable panel assembly 3 through the rotating shaftassembling components 1-5 of the support base assembly 1. When the rotating shaft assembling components 1-5 rotate, the deployable panel assembly 3 is driven to deploy so that the central fixing panel assembly 2 and the deployed deployable panel assembly 3 form a complete antenna reflector together. According to the deployable rigid reflector antenna, the deployable panel assembly is driven to rotate and deploy through the rotating shaft assembling components of the support base assembly so that the solid reflector antenna with large aperture, high accuracy, high rigidity and high storage rate can be realized.

Description

technical field [0001] The invention relates to the field of aerospace satellite communication, in particular to a deployable rigid reflection surface antenna. Background technique [0002] The reflector antenna has the characteristics of high single antenna gain and wide frequency band, so it is widely used in satellite communication, microwave communication relay, mobile communication base station, etc. Areas such as deep space communications play an important role. Except for satellite communications, the reflective surfaces of commonly used antenna structures today are mostly composed of rigid materials, which are large in volume and mass and cannot be folded and compressed. These shortcomings limit the application of such antennas. In the field of satellite communications, due to the limitation of the carrying mass and capacity of the space vehicle, the large-aperture antenna must be a deployable / foldable antenna, that is, the antenna is folded and stored in the fairin...
