Abstract

A capacitance-coupled bandpass filter is designed using miniaturized microstrip interdigital hairpin resonator. The full-wave simulator IE3D is used to design the compact hairpin resonator, and to calculate the coupling coefficient of the basic coupling strictures. The response of the fabricated filters using Al₂O₃ (ε_r = 9.7, Q×f = 350000 GHz) dielectric substrate are designed at a center frequency of 2.4 GHz. The compact size and the performance of this class of filter have been demonstrated.
