“…To meet the ever‐increasing practical application limits of the dual‐band wireless operation, dual‐band bandpass filters have been dramatically developed for multiband communication system. Various resonators have been introduced to realize the dual‐band bandpass filter with good performance, such as the ring resonator , the stepped‐impedance resonator (SIR) , and the spiral‐shape resonator . Nevertheless, the circuit size miniaturization is still a great challenge for the dual‐band bandpass filter design with good frequency responses.…”

A compact dual‐band bandpass filter using two sets of spiral resonators and loaded spiral open‐stub is proposed. The dual‐band resonances are introduced by the quarter‐wavelength (λ/4) spiral resonator and λ/2 asymmetrical spiral stepped‐impedance resonator, respectively. Then, the loaded spiral open‐stub tapped on the λ/4 spiral resonator is utilized for spurious shifting close to transmission zero, which can lead to spurious suppression for extended upper stopband. Finally, a dual‐band bandpass filter with good performance and size miniaturization is fabricated and verified experimentally. © 2014 Wiley Periodicals, Inc.

This paper presents a novel design of a compact dual band bandpass filter using stub loaded stepped impendence resonator. The center frequency of passband is 2.4 GHz and 3.75 GHz suitable for WLAN and WiMAX applications. The insertion loss at each passband is within 1.5 dB. Transmission zeros at either side of the passband renders high selectivity. The stop band performance of this dual band filter is satisfactory with the stop band extending up to 7 GHz. The overall dimension of the developed BPF is 20mm×15.5mm.
