DGS pattern with enhanced effective capacitance

A new defected ground structure (DGS) pattern with enhanced effective capacitance is presented. The increase in effective capacitance enables the new DGS pattern to achieve a lower resonance than the dumb-bell shaped DGS pattern for the same etched square area dimension. Simulation and experimental results show that a 1.32 GHz lower resonance is achieved with the new DGS pattern, compared to a dumb-bell shaped DGS pattern.
