A miniaturized end‐coupled microstrip band‐pass filter is realized using stepped‐impedance resonators (SIR). An experimental filter is designed at 5.7 GHz with a bandwidth of 300 MHz. The step impedance ratio of the SIR is 0.5. This filter exhibits compact size and spurious response that is not harmonically related to the fundamental passband. © 2005 Wiley Periodicals, Inc.
