Abstract

Defected Ground Structure (DGS) helps in improving the characteristics of many microwave devices. The
ground plane of the antenna is etched to change the various properties of the structure. The DGS on the ground plane
increases the fringing fields which introduces parasitic capacitance. This introduced parasitic capacitance increase the
coupling between the ground plane and the patch, as a result we get enhanced bandwidth. Hence the DGS can be assumed
to be an equivalent LC resonator circuit. The position and size of the defect determines the value of LC at a given
frequency. The design is suitable for WLAN 3.6/4.9 Ghz and WLAN 5-5.25 Ghz frequency. The simulation is carried out
using HFSS simulator.
