Abstract

Abstract : This Letter proposes a balanced dual‐mode substrate integrated waveguide (SIW) filter for the first time. Based on dual‐mode square SIW cavities, perturbation vias, and balanced ports, the quasi‐elliptic differential mode response with improved selectivity as well as high‐performance common mode suppression can be obtained conveniently. Resonator number decrease and compact size can also be available.
