Abstract
In the design process of a complete antenna system based on reflectors, the feed real performance is usually included once the reflectors have been optimized with an ideal feed. In this paper, the proposal is to include the feed inside the optimization loop of the whole system, by means of a parametric definition of the feeder. To perform the optimization, the parametric feed will be considered as an additional surface, which receives some desired electric field that should be analyzed to properly modify the feed definition parameters in order to reduce the difference between the desired and the new generated field distribution over a planar surface nearby the focal point of the system. At the end of the optimization process, all the elements of the whole antenna system, reflectors and feed, will be totally defined and perfectly coupled.
