Abstract :
A newly developed generalized reflector/feed(s) diffraction synthesis methodology that is capable of synthesizing various antenna configurations effectively is presented. Based on this synthesis method, the feasibility of several CBRA (contour beam reflector antenna) configurations, such as a paraboloidal reflector fed by a large array, a shaped reflector illuminated by a single feed, and a shaped reflector fed by a small, array, are properly assessed for a representative application in a unified fashion. Numerical examples are given to illustrate CBRA synthesis for a challenging and difficult contour coverage-the US Eastern Time Zone.<>
