Summary:
A new cascaded quadruplet (CQ) bandpass filter is proposed for size reduction using a mushroom-based metamaterial resonator which has an asymmetrically positioned via-hole. The proposed resonator has a zeroth-order resonant mode which is decreased as increasing the distance between a centre point of a mushroom patch and via-hole. Total size reduction rate of the resonator is about 38.8 % comparing with that of the conventional mushroom type resonator with a centre positioned via-hole. Using the compact mushroom resonator, the CQ bandpass filter is implemented and experimented. Details of not only the proposed resonator but also the CQ bandpass filter are presented in this paper.
