Abstract :
A method for synthesizing footprint patterns radiated by planar reflectors made of a large number of reflecting elements is presented. It is an extension to phase-only synthesis of a previous method that uses the modified Taylor expressions for circular apertures to provide good non-Phi-symmetric patterns. The possibility of selecting any kind of amplitude distribution allows the synthesis of patterns radiated for planar reflectarrays including those with an offset feed. As example, a footprint pattern fitting South America and Miami City was synthesized for a rectangular-grid circular boundary 3228-element reflectarray fed by an offset horn
