## 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
## Abstract A miniaturized microstrip crossβcoupling bandpass filter using new stepped impedance resonators (SIRs) with simultaneous suppression of the 2nd harmonic passband response is presented. Four improved and miniaturized SIRs constitute the compact filter, which exhibits a sharp transition b
