Rahul Sharma, A.N. Mishra

Abstract: In this paper a small size microstrip antenna with DGS (Defected ground structure) is designed and analyzed for UWB(Ultra Wide Band) application. This antenna cover the complete frequency range of 3.1 to 10.6 GHz with a very small geometry as compared to a conventional antenna Dielectric substrate use in this antenna is Fr-4. This antenna is designed with a dimension is 36mm × 34 mm on a dielectric substrate Fr-4 whose permittivity er =4.4 and height h = 1.6 mm. The result for return losses and radiation patterns is simulated by using HFSS (High Frequency structure simulation) software. The High frequency structure simulator is employed to analyze the planned antenna and simulated results on return loss, The ground element of the proposed antenna is taken in the form of defected ground structure (DGS).
