Abstract :
The authors determine the subreflector drive with minimum aberration. The calculated beam steering characteristics in the elevation plane are shown and discussed for a high-efficiency shaped reflector antenna with a 260 lambda -diameter aperture. For steering the beam in the azimuth plane, the position of the rotation axis and the rotation angle are determined by the same method.<>
