A general and effective reflector antenna synthesis approach is presented. Starting from the analytical properties of the scattered fields, a complete and simple operational relationship is established between the primary field and the secondary one. On this basis the reflector shape and the far field of the feed system are synthesized starting from the knowledge of only the dimensions and positions of the reflector and feed region. The technique makes it possible to synthesize essentially the same pattern with different reflector-feed couples, thus allowing the effects of the reflector shaping and the primary source extension to be balanced at the designer's convenience. The technique turns out to be numerically effective, as it is based on the use of fast Fourier transform.

Abstract
A general and effective reflector antenna synthesis approach is presented. Starting from the analytical properties of the scattered fields, a complete and simple operational relationship is established between the primary field and the secondary one. On this basis the reflector shape and the far field of the feed system are synthesized starting from the knowledge of only the dimensions and positions of the reflector and feed region. The technique makes it possible to synthesize essentially the same pattern with different reflector-feed couples, thus allowing the effects of the reflector shaping and the primary source extension to be balanced at the designer's convenience. The technique turns out to be numerically effective, as it is based on the use of fast Fourier transform.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
