✦ Synopsis

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 (BPF) has been designed and fabricated and its performances closely match the design data.

## Abstract This paper describes the microstrip stepped‐impedance resonator (SIR) bandpass filter with an over‐coupling structure for the suppression of spurious response at twice the center frequency (2f~__0__~). In addition, the tapped I/O is used in the filter to create the extra transmission ze

## Abstract 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 than 10 mm × 10 mm, which makes it sui
