A novel GO method for designing dual shaped offset reflector antennas with a prescribed phase and amplitude aperture distribution is presented. This technique consists of tracing rays consecutively by solving nondifferential equations. The solutions, which simultaneously satisfy the amplitude and phase requirements, together with the total derivability condition of the surface expressed in a new discretized way, are easier to control than the other techniques in the literature. This algorithm accounts for the feed phase errors. Two examples are selected to show the good performance of the algorithm. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 15: 20–26, 1997.
