Abstract A new compact configuration of a stepped‐impedance comb‐line filter is proposed. By reversing one of the two resonators, the size of the filter becomes much smaller than that of the former. The impedance ratio has a small effect on the filter's size. The filter is made of low‐temperature co‐fired ceramic (LTCC). The simulated frequency characteristics are compared with the measured data of the fabricated filter and good agreement is reported. © 2004 Wiley Periodicals, Inc.
