## Abstract A folded quarterโwavelength 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 ร 10 mm, which makes it sui

This paper proposes a novel resonant element using a slotted ring resonator in conjunction with the stepped impedance resonator (SIR). With this structure, the basic resonant element exhibits the first spurious harmonic close to 3 f 0 . By cascading the two basic units, a compact bandpass filter (BP
## Abstract A new dualโband bandpass filter (BPF) for 2.4/5.2 GHz WLAN systems using twoโstepped impedance resonators is presented. With new properly coupled structure, this filter appears very compact and easy to be fabricated. Measured results show that this BPF has low insertion loss of 0.3 dB a
## Abstract A modified compact steppedโimpedance hairpin resonator using an interdigital capacitor and its application to a bandpass filter design are presented. In comparison to the coupled line of a conventional steppedโimpedance hairpin resonator, the interdigital capacitor of the proposed reson
