Abstract
An antenna () for microwave radiation including a first horn () which includes a plurality of corrugations (). At least one of the corrugations () is formed of a frequency selective surface (FSS) (). The FSS has a plurality of FSS elements () coupled to at least one substrate (). The substrate () can define a first propagation medium such that an RF signal having a first wavelength in the first propagation medium can pass through the FSS (). The FSS () is coupled to a second propagation medium such that in the second propagation medium the RF signal has a second wavelength which is at least twice as long as a physical distance between centers of adjacent FSS elements ().
