| Abstract(in English) | Recently, engineers have focused on developing mobile satellite communications and broadcasting system using GEO satellite. We are now studying array fed large reflector antenna system, for using hand-held terminals. Phased array fed reflector antenna is fed from the defocus point. In this paper, we will first propose a method getting a defocus length for maximum antenna gain. and, present relationships between the defocus length and array aperture distributions etc. |
