## 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
## Abstract In this article, parallel‐coupled microstrip line (PCML) with ground plane aperture is used to improve the stopband performance of a stub tuned dual mode ring resonator band‐pass filter (BPF). The PCML with ground plane structure produces a wide‐band band‐pass response, whereas the stub
