摘要：

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 filler exhibits compact size and spurious response that is not harmonically related to the fundamental passband. (c) 2005 Wiley Periodicals, Inc.
