Abstract :
A novel compact and simple shape of defected ground structure (DGS) is introduced for microstrip applications. The DGS cell is etched on the ground plane between the array elements or in filter applications. Three shapes of DGSs, namely narrow strip, symmetric comb and asymmetric comb, are proposed, analyzed and compared. Parametric studies of DGS parameters for a transmission line loaded with unit cell DGS are presented. The results indicate that the asymmetric comb shaped DGS is better at suppressing propagation of surface waves in microstrip substrate.
