Abstract

Frequency Selective Surfaces (fss), used as quasioptical diplexers in reflector antenna systems for telecommunication satellites are attracting much interest, since they allow multifrequency illumination of the main reflector, with consequent mass saving. In this paper the spectral characterization of these surfaces is discussed, and the solution of the scattering problem via the Moment Method is described. The general characteristics of the frequency response of fss are reviewed, when the incident field is a plane wave. Then a method is presented to analyse the behaviour offss in their actual operating environment, even in the near field region of the feeds.
