摘要
A folded quarter-wavelength 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 titan 10 mm x 10 mm, which makes it suitable for compact and high-performance microwave circuit applications.
