MOBILE SATELLITE SUBSCRIBER EARTH STATION Russian patent published in 2024 - IPC H04B7/26 H01Q1/24 H01Q3/08 H01Q19/18 H01Q21/06 

FIELD: physics.

SUBSTANCE: invention relates to mobile satellite communication facilities and can be used to organize satellite communication radio links when operating through communication spacecraft (SC) transponders and broadcasting, located on geostationary and high-elliptical orbits (GEO and HEO) in motion. Mobile satellite communication subscriber earth station includes receiving and transmitting apertures consisting of planar active phased antenna arrays (APAA), which is a multilayer printed circuit board, on the outer side of which there are bipolarized printed group antenna elements, and on the inner side there are eight-channel, respectively, transmitting and receiving monolithic integrated circuits (MIC) for beamforming and arbitrary polarization, providing together with antenna elements electronic scanning in angular area ±3° by azimuth and ±20° by elevation angle and polarization vector matched with polarization of spacecraft transponders.

EFFECT: high accuracy of pointing and stabilizing the angular position of the beam of subscriber earth stations in motion.
