## Abstract A tri‐band microstrip bandpass filter using folded tri‐section stepped‐impedance resonators is designed, analyzed, and fabricated in this article.Furthermore, the filter's coupling structure analysis and equivalent circuit model are discussed theoretically, and the design methodology of
