Annular Waveguide Analysis for Application in Annular Waveguide Slot Antennas (AWSA)

Siamak Ebadi, Keyvan Forooraghi

Abstract

Detailed analysis of propagating fields in an annular waveguide for application in an annular waveguide slot antenna (AWSA) is presented in this paper. Exact field distributions along with cut-off and resonant frequencies are obtained for travelling and standing wave cases and compared with rectangular waveguide. The theoretical results are verified by a single slot AWSA design, simulation and measurements at 9.3 GHz and interesting similarity is observed.
