Abstract

A compact microstrip dual‐band bandpass filter (DBBPF) with controllable bandwidth for each passband is proposed. Each passband is independently designed using two different dual‐mode resonators. The proposed DBBPF has three transmission zeros. Two transmission zeros are generated by each dual‐mode resonator. An additional transmission zero is generated by input/output port coupling. The DBBPF application is designed for 2.4/5.7 GHz WLAN. Experimental measurements are presented to validate the theory. © 2011 Wiley Periodicals, Inc.

## Abstract This paper presents a dual‐band bandpass filter by introducing transmission zeroes in the passband of a broadband bandpass filter using square‐loop dual‐mode resonators. The transmission zeroes are achieved by using a dual‐mode resonator. The dual‐mode resonator is attached to two trans

## 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

## Abstract We propose a compact dual band bandpass filter (BPF) using meandering stepped impedance resonators (SIRs). By appropriately selecting the impedance ratio (K) of the SIR, the harmonic frequencies can be tuned for generating the dual‐passband response. Using this structure, the bandwidth
