摘要：
This Letter proposes a novel balanced triple-mode substrate integrated waveguide (SIW) bandpass filter for the first time. The new triple-mode resonator is realised by a square-shaped SIW cavity with a capacitive loading patch. The resonance of higher-order mode TE301 can be controlled and shifted to that of modes TE102 and TE201. High-performance common mode suppression, controllable bandwidth, compact size and quasi-elliptic differential mode response can be achieved. For demonstration, a balanced triple-mode SIW filter is designed, fabricated and measured.
