Resumen
Descripción
We perform EM simulations of a lowpass microstrip filter consisting of a crossjunction open stub and two unit sections implemented as defected ground structures (DGS). The defect introduced by unit sections corresponds to an etched lattice on the copper backside ground plane. The filter presents wide and deep attenuation characteristics in the stopband. Different model implementations were carried out with the aim at evaluating the computational costs versus accuracy. Simulations of a high-fidelity model are in good agreement with experimental data reported in a previous paper. COMSOL simulation settings, enclosing box, computational costs, and simulation times for the considered models are provided.
