摘要: A compact dual-mode dual-band bandpass filter (BPF) is proposed in this article. T-shaped slot etched on the center of low-impedance part a stepped-impedance resonator, which mainly impact pairs high-order modes resonator. By tuning length and width slot, both dual-modes resonator can be controlled, implying that bandwidth controlled. The feed line folded to fulfill external coupling dual-passband. BPF for 2.4 3.5 GHz application designed, fabricated, measured. Agreements between measured results simulated verify structure. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1057–1060,
