摘要：

A dual-band bandpass filter using two embeded stepped impedance resonators is proposed. To validate the proposed structure, the prototype filter has been fabricated and measured. Two stepped impedance resonators are embedded in a half-wavelength resonator and thus the proposed filter is compact in size. The results show the passbands with 3dB fractional bandwidth of 15.2% and 14.5% at 1.65GHz and 2.75GHz, respectively. The measurement results agree well with the full wave electromagnetic designed responses.
