MICROSTRIP ANTENNA WITH DEFECTED GROUND STRUCTURE: A REVIEW (original) (raw)

Defected Ground Structure is a new face or we can say a new era of research and application on printed circuit Microstrip antennas. Since DGS used antenna has a different ways of understanding about the Microstrip antennas it is being introduced in this paper to give a broad perspective and understanding about DGS. Intentionally created error or the slot in the ground plane of a Microstrip antenna is referred as the Defected Ground Structure (DGS) and is used for different applications. The defects introduced in the ground plane can be single or multiple. The defects are introduced to reduce the harmonics and to suppress mutual coupling between elements. DGS has opened a new face of exploration in the fields of microwave engineering which leads to thousands of applications and developments till date. Many patents are been already made using DGS in antennas and there are many technical papers, articles. In this paper it is tried to introduce to the new face of development especially in the field of Microstrip antennas, giving an insight to applications and developmental challenges on microstrip antennas in improving, bandwidth, polarization, compactness in size and multiband applications.
