Coverage shaping of contoured-beam antennas by aperture field synthesis
Abstract
A synthesis method for high-gain antennas with beams of elliptical or even more complicated cross-sections is developed. The desired beam contour is realized in an offset reflector with circular aperture illuminated by a single feed by optimizing 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.
