摘要：
In this paper, a novel design for miniaturized microscript bandpass filter based on the twist split ring resonators (TSRRs) is analyzed systematically. The proposed TSRRs printed on the conventional dielectric substrate with full size ground plane exhibit two resonance states separated each others. And the two resonance frequencies can be tuned by changing the distance between the two single split ring resonators. We first discuss the resonance characteristics and optimize the designed filter with finite element method based simulator (Ansoft HFSS V14). Then the designed microscript bandpass filter is fabricated by standard printed circuit board techniques. Finally, the proposed filters are numerically and experimentally discussed in details, including the passband, out-of-band suppression, and higher order properties. Both results show that the proposed filter exhibits a compact size and well passband characteristics, which can be used in radio frequency/microwave integrated circuits.
