Abstract
A method for reducing phase aberration in an antenna system for satellite, the antenna system being configured to receive and/or emit at least a spot beam, the antenna system including a reflector; an array feed including a plurality of feeds configured to illuminate the reflector in emission mode and/or configured to receive illumination from the reflector in reception mode; a trimming system configured to adjust the position of the reflector with respect to the array feed, the method including adjusting the position of the reflector with respect to the array feed in order to correct phase aberration in the spot beam.
