Problems solved by technology

[0002] The larger the aperture of the spaceborne antenna, the higher the antenna gain. The size of the existing antenna is limited by the size of the rocket fairing, and the launch of the large-aperture antenna cannot be realized.
The air environment is complex, and once the antenna is damaged, it cannot be repaired
The size and shape of the existing spaceborne antenna cannot be changed, and new functions cannot be expanded

Abstract

The present invention provides a multi-satellite assembleable antenna device, comprising at least one satellite antenna module, the satellite antenna module includes an antenna module and a satellite module, the antenna module is mounted on the satellite module, and the antenna module At least one group of fixed modules is arranged on the antenna module; the fixed module includes a matching first fixed structure and a second fixed structure, and the first fixed structure and the second fixed structure are respectively arranged on opposite ends of the antenna module; The movement of the satellite modules drives the adjacent satellite antenna modules to approach, and the on-orbit assembly or disassembly is realized through the first fixing structure and the second fixing structure. The multi-satellite assembleable antenna device provided by the invention breaks through the inherent mode of the satellite-borne antenna, and is made into an assembleable form, which has high use value.

Description

technical field [0001] The invention relates to the technical field of satellite-borne antennas, in particular to a multi-satellite assembleable antenna device. Background technique [0002] The larger the diameter of the spaceborne antenna, the higher the antenna gain. The size of the existing antenna is limited by the size of the rocket fairing, and the launch of a large-diameter antenna cannot be realized. The air environment is complex, and once the antenna is damaged, it cannot be repaired. The existing spaceborne antenna size and shape cannot be changed, and new functions cannot be expanded. SUMMARY OF THE INVENTION [0003] In view of the problems in the background technology, the present invention provides a multi-satellite assembleable antenna device, which includes at least one satellite antenna module, the satellite antenna module includes an antenna module and a satellite module, and the antenna module is installed on the satellite module. The antenna module ...
