## Abstract In this article, we propose a novel ultraโwideband bandpass filter with an improved upper stopband characteristic and a notched band. The proposed BPF is composed of a coupled doubleโstep impedance resonator, an interdigital slot, a dumbbellโshaped defected ground, and an openโloop defe
## Abstract This article presents a synthesis of the ultraโwideband bandpass (UWB) filters consisting of two shortโcircuited stubs combined with two stages of stepped impedance resonators (SIRs).The practical and theoretical transfer functions of the proposed UWB filters are derived. An example fil
A pseudo-interdigital stepped impedance resonator (SIR) bandpass filter (BPF) using tapped I/O is designed and fabricated. By using a pseudo-interdigital structure and the SIR, the proposed BPF gains advantages of compactness and high selectivity. In this paper, the first and second spurious respons
