A beam-steerable antenna with an offset spherical reflector for earth station
Abstract
This paper proposes a newly devised beam-steerable antenna which may suggest a future large scale earth station antenna for satellite communications. This is an offset type spherical reflector antenna with two specific subreflectors and a trireflector beam-waveguide feeder. It can steer its radiation beam without moving the main reflector and the feed horn. An experimental model antenna of 2 x 3 m at 52/34 GHz corresponding to a 20 m class antenna at 6/4 GHz has demonstrated its excellent electrical performance over wide scanning angles.
