Abstract

The invention discloses a structure of a high-precision reflector antenna composite panel and an adjustment method thereof and belongs to the field of high-precision antenna preparation technologies.The structure comprises a main antenna body composed of a high-precision reflector and an antenna back rack, the main antenna body is subjected to relevance-type pre-adjustment through a coarse adjustment disc used for first-level adjustment and subjected to second-level adjustment through a fine adjustment threaded rod used for second-level adjustment after pre-adjustment, and the coarse adjustment disc for first-level adjustment can achieve linkage adjustment on the positions and poses of N panels (expanding to the whole reflector antenna structure, N is equal to 1-6) on the upper portions of panel adjustment points. The whole structure has the advantages of being simple, high in adjustment efficiency, low in weight and processing cost, high in reliability and the like and is particularly suitable for all kinds of reflector antennas with the antenna aperture larger than 18 meters and the working frequency band above the Ka frequency band.

Description

technical field [0001] The invention belongs to the field of high-precision antenna devices, and relates to the structure and adjustment method of a high-precision reflector antenna combination panel in the field of reflector antennas, and is especially suitable for reflectors with large diameters, small curvatures, and operating frequencies above the Ka frequency band Antennas are also used as manufacturing and adjustment technology for high-precision reflector adjustment devices. Background technique [0002] With the great progress of deep space exploration and satellite communication technology, antennas have played a pivotal role in it. The antenna mainly transmits and receives signals through a reflective surface of a specific size. Related technologies require higher and higher operating frequencies of antennas, and furthermore, require higher and higher profile precision of reflector antennas. The adjustment method of the high-efficiency combined panel adjustment d...
