Abstract:
It is noted that multipath hybrid-mirror antennas used in satellite communication systems in the geostationary orbit have increased requirements to maintain the accuracy of aiming radiation patterns. To solve this problem, there are mechanical and electronic methods of reflector deformation of 0,075 m. These results confirm the operability of the used algorithm for modeling large-sized MBHA.
