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 (εr = 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.
