Abstract

A novel compact microstrip dual‐band bandpass filter (BPF) is developed with remarkably improved stopband characteristics. Two‐square open‐loop resonators are embedded in a U‐shaped resonator to achieve a significant size reduction of the filter. Meanwhile, a cross‐coupling between nonadjacent resonators is exploited to produce multiple transmission zeros in the stopbands of the filter. As a consequence, wide stopbands with sharp and large attenuations are obtained. Theoretical and measured frequency responses of the designed filter show a good agreement.© 2008 Wiley Periodicals, Inc.

## Abstract In this work, a novel microstrip bandpass filter with a wide stopband is proposed. With the assistance of an open stub, one modified open‐circuit coupled line with symmetrical feeding, a long transmission line, and a wide stopband with a sufficient rejection level can be achieved.

## 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

## Abstract In this article, a dual‐band bandpass filter is designed by using microstrip stub‐loaded two‐mode resonators. Because the resonant frequencies of the odd‐mode and even‐mode of the stub‐loaded resonator can be varied individually, the midband frequencies of the dual‐bands of filter can b
