In this letter, a multilayer balanced substrate-integrated waveguide (SIW) bandpass filter (BPF) using the TE₁₀₂ and TE₂₀₁ modes is designed with an aperture etched on the common ground between two stacked SIWs. Under common-mode (CM) operation, the aperture is a perfect magnetic conductor (PMC). Wh...
