We have developed the advanced onboard antennas for High Throughput Satellite (HTS). They are three types of the antennas utilizing Ka-band frequencies to aim in-orbit verification by the Japanese Engineering Test Satellite 9 (ETS-9). First antenna is the fixed multi-beam antenna (Fixed MBA) employing the miniaturized and integrated feeder unit to enable dense allocation of multi beams for improvement of spectrum efficiency. Second antenna is the Digital Beam Forming antenna (DBF-ANT) to enable flexible beam shape. Third antenna is the common communications system antenna (CCS-ANT) transmitting broad beam which has beacon transmission function etc.
