Direct and cross-coupled resonator filters using defected ground structure (DGS) resonators

Abstract

This paper introduces DGS resonators to be used as building blocks of coupled resonator filters. Different coupling configurations are considered. These new resonators are then applied to design a multilayer second-order coupled resonator bandpass Chebychev filter and a fourth order cross-coupled resonator pseudo-elliptic filter. Experimental results are… (More)
