Abstract :
This paper introduces new compact DGS resonators and ways to implement intra-resonator and external coupling. Different coupling configurations are considered. These new resonators are then applied to design bandpass filters with Chebyshev or pseudo-elliptic responses. Experimental results are presented to show the performance of these filters.
