A four‐pole elliptic function bandpass filter is designed using compact miniaturized microstrip interdigital hairpin resonator. Miniaturization hairpin resonator is realized by using an interdigital structure having parallel coupled lines. The full‐wave simulator IE3D is used to design the interdigital hairpin resonator and to calculate the coupling coefficient of the basic coupling strictures. The response of the fabricated filters using FR4 substrate is designed at a centre frequency of 1.8 GHz. The compact size and the performance of this class of filter have been demonstrated. © 2009 Wiley Periodicals, Inc.
