Abstract-A four-pole elliptic function compact bandpass filter is designed by using interdigital hairpin resonator and step-impedance hairpin resonator.The miniaturized band-pass filter is also implemented using high permittivity dielectric substrate. The fullwave simulator IE3D is used to design the compact hairpin resonator, and to calculate the coupling coefficient of the basic coupling strictures. The responses of the fabricated filters using Al 2 O 3 (ε r = 9.7, Q × f = 350000 GHz) and 0.6Sm(Co 1/2 Ti 1/2 )O 3 -0.4CaTiO 3 (ε r = 37, Q × f = 43000 GHz) dielectric substrates are designed at a center frequency of 2 GHz. The size of the compact hairpin filter using 0.6Sm(Co 1/2 Ti 1/2 )O 3 -0.4CaTiO 3 ceramic substrate, as compared to that of a compact hairpin filter using Al 2 O 3 ceramic substrate, is reduced in size by 45%. The compact size and good agreement have been obtained between simulations and implementation results.
