摘要：
A novel bandpass filter using a dual-mode square-patch resonator is proposed in this letter. The input and the output of the filter are constructed on a coplanar-waveguide (CPW) and a microstrip line, respectively. Therefore, a transition of CPW/microstrip may be simultaneously realized by using the filter. The filter has been finvestigated numerically and experimentally. Measured results show that the minimum insertion loss in the passband of the filter is about 2.1 dB and its out-of-band. rejection level is below-23 dB.
