Abstract :
This paper describes the development of the slot array antenna system for the COMETS advanced mobile satellite communication experiments. COMETS is a Japanese engineering test satellite for Ka/Q-band mobile satellite communications, and is-scheduled for launch into geostationary orbit in the summer of 1997. The Communications Research Laboratory (CRL) has developed a compact mechanically steered antenna system for the COMETS mobile terminal. System performance with a high efficiency antenna and control electronics are discussed
