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. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:998–1001, 2016
