Architectures for active multiple-feed-per-beam satellite antennas with power amplifiers shared between adjacent beams are presented. Different concepts for sharing solid state power amplifiers (SSPAs) to reduce required power margins for a K-band scenario are proposed and compared. In scenarios with data traffic and rain attenuation unequally distributed across the beams the overall efficiency can be increased.
