Parameter Enhancement and Size Reduction using DGS of L Band Antenna

Abstract

Proposed research is the outcome of the detailed literature review and intensive research carried out in the field of parameter improvement of antenna using defected ground structure. In this paper a patch antenna is proposed with the introduction of a slit ring DGS structure to modify its parameters and reduce the size of antenna. Antenna was designed and simulated at 1.95GHz initially but after implementing DGS its radiation efficiency is shifted to 1.58GHz which theoretically a sign of size reduction of antenna. DGS is actually a cut made in the ground plane of the antenna which create a disturbance in radiating power, this disturbance in the ground basically distributes the radiating frequency and make antenna more efficient than ever before.
