Abstract: Abstract Communicat ion satellites achieve global communication coverage by using high gain multibeam satellite antennas. In geostationary satellites, large reflector antennas fed by cluster feeds arranged on the focal plane are common to meet the requirement of high gain and fixed multibeams. Adopting phased array antennas for a geostationary satellite is attractive because they offer power reallocation according to traffic demand, reconfigurability of beams, and maintainability of beam pointing. This paper provides an analytical study of the phased array fed single reflector antenna and clarifies that the feed element number is the most important design parameter Calculated radiation properties prove the usefulness of the antenna as a large scale multibeam antenna
