A compact wideband bandpass filter with multiple transmission zeros is proposed in this paper. Three transmission zeros in the upper stopband can be realized by different open/shorted stubs. The bandwidths of the bandpass filter can be adjusted easily by changing the characteristic impedance of the open/shorted stubs. A bandpass filter with 3‐dB fractional bandwidth of 110% (0.51 − 1.76 GHz) is fabricated and measured. Good agreement can be observed between simulated and measured performances. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2452–2456, 2016
