ABSTRACT
A cavity model-based analysis of electric field propagation inside a six-port Riblet-type directional coupler has been presented in this paper. Though cavity modeling technique is not very new and was previously applied to different rectangular waveguide-based passive networks to find their network parameters, for the first time it has been used here to analyze the field propagation inside a six-port Riblet-type directional coupler. From the analysis, the frequency response of the network has been estimated. Since the main objective of this work is to analyze the field propagation inside a passive network, not to present another network, a six-port Riblet-type directional coupler that is already proposed in literature has been considered. The numerical analysis has been verified by comparing the scattering parameters data obtained from the cavity model analysis with CST Microwave Studio simulation data and measured data available in the literature.
