摘要: In this letter, an ultra-wideband (UWB) bandpass filter (BPF) using stepped-impedance stub-loaded resonator (SISLR) is presented. Characterized by theoretical analysis, the proposed SISLR found to have advantage of providing more degrees freedom adjust resonant frequencies. Besides, two transmission zeros can be created at both lower and upper sides passband. Benefiting from these features, a UWB BPF then investigated incorporating aperture-backed interdigital coupled-lines. Finally, built tested. The simulated measured results are in good agreement with each other, showing wideband filtering performance sharp rejection skirts outside
