Abstract : Advanced offset-fed spacecraft antenna systems are being developed for the National Aeronautics and Space Administration (NASA) that will provide multiple radiating fixed spot-beams and regional coverage scanning beams for use on communications satellites operating in the 30/20 GHz frequency bands. Design concepts under development utilize two separate spacecraft antenna systems, one uplink at 30 GHz and the other a downlink at 20 GHz, where each antenna provides multiple fixed and scanning beams.
