Abstract(in English)	The high data rate and global satellite communication systems are expected to be an important agenda to the social and economic activities in the 21^ century. The experimental high data rate(Gigabit)communications satellite is required technological challenges for the future growing multi-media applications. For this Gigabit communications system, a Ka-band scanning spot bean antenna(SSBA)which realizes multiple bean forming is required. CRL and MELCO have been developing Ka-band active phased array antenna(APAA)for the SSBA as one of the most important and challenging technology. CRL and MELCO are investigating and developing the direct radiating APAA for SSBA which can operate under wide frequency band in Ka-band. This paper describes the preliminary study results of the Ka-band APAA for Gigabit Satellite and the experimental result such as bean scanning performance of the partial experimantal model with two multiple beams for both transmit and receive. We also verified that the REV(rotating element electric-field vector)method was effective for pattern calibration.
