Abstract

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. © 2009 Wiley Periodicals, Inc.

## Abstract A dual‐band microstrip bandpass filter with controllable bandwidth is proposed by using new dual‐band resonators. The resonator consists of a pair of shunt open stubs, including a stepped‐impedance open stub. The open stubs produce three transmission zeros, which result in sharp attenua
