Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, multibeam satellite systems with hundreds of spot beams have been developed and studied. A Multibeam satellite system realizes adaptive frequency allocation for efficient frequency reuse, and has the flexibility to control traffic in communication. Multi-port Amplifier (MPA) has been also developed to share efficiently the transmission power of the satellite among the beams. In this paper, multibeam digital beamforming (DBF) antenna using MPA is proposed to achieve higher performance. It was confirmed to achieve SINR 35dB or more by three beam transmission experiments.
