The invention discloses a large-scale expandable fixed surface antenna, which comprises a plurality of main reflecting antennas which are combined to form an antenna main reflecting surface after being expanded in place, a main reflecting support assembly for supporting the plurality of main reflecting antennas, a main reflecting antenna expanding assembly which is used for controlling the switching of expanding and folding states of the plurality of main reflecting antennas, a plurality of subsidiary reflecting antennas which are combined to form an antenna subsidiary reflecting surface after being expanded in place, a subsidiary reflecting support assembly for supporting the plurality of subsidiary reflecting antennas, and a subsidiary reflecting antenna expanding assembly which is used for controlling the switching of expanding and folding states of the plurality of subsidiary reflecting antennas, wherein the plurality of main reflecting antennas and the plurality of subsidiary reflecting antennas are used for forming a complete antenna reflecting surface together after being expanded in place. The large-scale expandable fixed surface antenna provided by the invention is simple in structure, the main reflecting antennas and the subsidiary reflecting antennas can be folded and compressed, the storage rate is small, the weight is light and the cost is low.
Description
technical field [0001] The invention relates to the communication field, in particular, to a large-scale deployable solid-surface antenna. Background technique [0002] In recent years, my country's aerospace industry has developed rapidly, and a series of major aerospace science and technology projects have been implemented, such as manned spaceflight, lunar exploration programs and new launch vehicles, all of which are inseparable from antennas. As a device that radiates into space or receives electromagnetic waves from space, antenna is an essential part of the communication system of aerospace equipment. With the increase in the amount of transmitted information, the demand for antennas with characteristics such as large capacity, high power, and multi-spectral bands has become more and more urgent. This must be based on the premise of increasing the antenna aperture and improving the antenna accuracy. Due to the limitation of the volume of the fairing of the space vehi...
