摘要: An ultra-wideband (UWB) bandpass filter (BPF) with two sharply rejected notch bands based on a folded stepped impedance resonator (SIR) is investigated. The proposed UWB BPF comprises four shunt quarter-wavelength short-circuited stubs, and coupled SIRs metallised via holes to ground. are studied employed generate the desired notched bands. predicted results compared measured data good agreement reported.
