## Abstract In this letter, a compact dualβband microstrip bandpass filter (BPF) with independently controlled center frequencies is designed using meander shortβcircuit quarterβwavelength resonators. Its coupling scheme and equivalent circuit model are analyzed. A good agreement between simulation
A four-pole elliptic function bandpass filter is designed using miniaturized microstrip interdigital hairpin resonator and stepimpedance hairpin resonator. Miniaturization hairpin resonators are realized by using interdigital structure and step-impedance structure having parallel coupled lines. The
## Abstract A folded quarterβwavelength stepped impedance resonator (SIR) is proposed with a largely reduced size. A bandpass filter with center frequency of 1.85 GHz using the SIRs is designed, fabricated, and measured. This compact filter covers an area less than 10 mm Γ 10 mm, which makes it sui
