Abstract
The author describes an array-fed dual imaging reflector antenna at 36 GHz. The antenna system comprises a large parabolic main reflector fed from a small linear phased array via a confocal Gregorian subreflector. The phased array is magnified by the two reflectors and an image of the near field of the phased array is formed on the aperture of the reflector. The scanning capability of the antenna system is demonstrated. Typical antenna patterns computed for a 100- lambda diameter main reflector operating at 36 GHz are shown.<>
