Abstract:A simple circuit model is presented for modeling substrate integrated waveguide (SIW) series-fed dielectric resonator antenna (DRA) array. The mutual coupling between antenna elements is taken into account in the model. A singleelement and a two-element antenna structures are simulated first using full-wave solver. The mutual coupling between antennas is then extracted and subsequently plugged into the circuit model for the antenna array. A millimeter-wave DRA array example is used to validate the model. The S… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
