Abstract :
This paper proposes a novel resonator to achieve miniaturization of combline filter. The proposed resonator is similar to helical resonator. To demonstrate the validity of the proposed resonator, a pass-band filter with a center frequency of 160MHz and a relative bandwidth of 50% is presented. Simulation results show that this new design can reduce the dimensions by 25% compared with the conventional combline filter with M-shaped structure of capacitance-loaded.
