A new approach is proposed for the study of a planar Fabry-Perot antenna. A reliable description of the coupling between the cavity and the feeding waveguide is developed by taking into account for all the relevant eigenfunctions both in the waveguide and into the cavity. The cavity field is used to compute equivalent currents on radiating apertures, obtaining from them the radiated far field. The approach can be adopted for the analysis as well as for the synthesis of a large variety of cavity antennas.

Abstract
A new approach is proposed for the study of a planar Fabry-Perot antenna. A reliable description of the coupling between the cavity and the feeding waveguide is developed by taking into account for all the relevant eigenfunctions both in the waveguide and into the cavity. The cavity field is used to compute equivalent currents on radiating apertures, obtaining from them the radiated far field. The approach can be adopted for the analysis as well as for the synthesis of a large variety of cavity antennas.File in questo prodotto:
