A compact ultrawideband (UWB) bandpass filter with a controllable notched band within the UWB passband is proposed on the basis of a stub-loaded modified stepped impedance resonator (SIR) and two identical interdigital feed-lines. In the design, the modified SIR and the interdigital feed-lines can work together properly to make up the desired UWB passband. The stubs loaded at each side of the modified SIR can generate a desired notched band within the UWB passband to avoid the interference from wireless local-area network. There are good agreements between the simulated and measured results.
