A Review on Microstrip Antennas with Defected Ground Structure Techniques for Ultra-Wideband Applications

Wireless communication systems have grabbed predominant role in disparate areas of human civilization. Wireless applications have great demand which initiates the new specifications for the architecture of transmitter and receiver in radio communication system. In the study of microstrip antennas, Defected Ground Structure(DGS) is a new approach which has many applications in various domains. This paper presents the knowledge of DGS and the consequences of it’s developments. The improvement of different characteristics of DGS antennas are studied in this paper. DGS has unfolded new aspects of research in microwave engineering field which leads to several advancements till date. DGS technology can be applied to metamaterial microwave antennas and microstrip antenna arrays for the improved performance of microwave devices. The range of applications can be widened by merging DGS technique with the other developments in microwave devices. In the proposed approach DGS Technology based metamaterial antennas can be developed for obtaining the better performance in UWB microstrip antennas. Band notch can be used to reduce interference in UWB frequency ranges.
