摘要

A novel bandpass filter (BPF) with multiple transmission zeros (TZs) and wide stopband is proposed. The filter is realised using complementary open-ring resonators (CORRs) loaded half mode substrate integrated waveguide (HMSIW). Besides, a novel electric source-load electric cross-coupling configuration is introduced to generate extra attenuation poles at either side of the passband, which improves the passband selectivity and the stopband suppression level. Based on this structure, a BPF operating at 5.8 GHz with multiple transmission zeros is designed and fabricated. The Measurement and simulation results indicate that the proposed configuration is a good candidate for filter design.
