摘要：

A compact dual-band bandpass filter using loop resonators is proposed in this paper. The filter is designed for resonance frequencies of 1.8 GHz and 2.4 GHz. It is fabricated on RT/Duroid 6010 with h = 1.27 mm and a relative dielectric constant epsilon(r) = 10.8. This filter has achieved excellent scattering parameters and size reduction of approximately 30% compared to conventional microstrip filters. The measured fractional bandwidths are 1.66% and 3.54% at 1.8 GHz and 2.4 GHz, respectively. The filter is evaluated by simulation and measurement with very good agreement.
