Abstract :
On-board antennas of 2.5/3.5 m in diameter which cover Japan with 13 beams in 30/20 GHz bands are developed. To achieve intense frequency reuse, a 9-horn cluster feed is adopted. A tower mounted type deployable antenna configuration is selected so as to overcome the fairing envelope limitation
