摘要：

In this paper, a novel passive dual-band bandpass filter using microstrip loop resonators is proposed, which allows two transmission paths to microwave signals. Each of them using dual-mode resonators results in respective passband. This can provide convenience to easily change one passband frequency, while another keeps almost the same. Several attenuation poles in the stopband are realized to improve the selectivity of the proposed bandpass filter. It is designed and simulated on RT/Duroid6010 substrate with permittivity of 10.8 and thickness of 1.27 mm. Compact size, low loss, dual band and high selectivity characteristics are realized by this type of filter structure. The filter of this type has 0.9% and 1.4% bandwidth at 1.8 GHz and 2.4 GHz, respectively.
