In this paper, a compact microstrip bandpass filter with wide stopband performance is presented. Wide stopband performance is achieved by introducing both stepped‐impedance resonator and over‐coupling technique. With the new structure, the filter has not only wide upper stopband performance with harmonic frequency outside 5 f 0 but also compact size. © 2007 Wiley Periodicals, Inc.
