## 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
## Abstract In this article, a series of compact dual‐band bandpass filters are proposed using the stepped‐impedance stub loaded hexagonal stepped‐impedance resonator. The resonator has three functions in the filter as follow: (1) dual‐resonances operation introduced by the first‐ and second‐resona
