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 presented to show the performance of these filters.
