Abstract

This letter proposes a novel balanced triple-mode microstrip bandpass filter based on a double-sided parallel-strip line resonator for the first time. The triple-mode resonator is realized by a stub-loaded structure. Stripline-like structure is employed to excite the triple-mode resonator under differential mode operation. Meanwhile, good common mode suppression can also be achieved. For the demonstration, a balanced triple-mode microstrip filter was designed, fabricated and measured.
