Abstract
A synthesis method for high-gain antennas with beams of elliptical or even more complicated crosssections is developed. The desired beam contour is realised in an offset reflector with circular aperture illuminated by a single feed by optimising the phase of the aperture field. A number of cases are presented in which the desired contour is an ellipse. The results are checked by a reflector antenna analysis program using physical optics.Keywords
