A novel bandpass filter with multiple transmission zeros using open/shorted dual‐behaviour resonators (DBRs) is proposed. Three transmission zeros on both sides of the bandpass responses can be easily realised. Three additional transmission zeros without bandstop/lowpass networks are used to suppress the second harmonic. A bandpass filter prototype with 15 dB rejection level in the upper stopband from 1.1 f 0 to 2.72 f 0 (3 dB fractional bandwidth 7.3%) has been designed and fabricated.
