Abstract: The objective of this paper is to design and analysis of the Ultra wide Band Micro strip Patch Antenna which covers the Ultra Wide Band 2.9 to 21.5 GHz. To get an optimum results and performance of the projected self complementary UWB antenna depends on the study of dissimilar methods for optimizing the different parameters of the radiating patch along with notch dimensions. The proposed self complementary UWB antenna with overlapped rectangular shape patch and Defected DGS is designed with C-Slot in the radiating patch element and ground with L shaped slot which covers the whole UWB frequency band apart from band notches WLAN (5.125-5.825 GHz) ,Satellite Communications (7.9-8.5 GHz) and Ku band 13.4-14.5GHz.The UWB antenna performance is improved in terms of the Bandwidth by including Rectangular shaped slit between feeding element and the radiating patch. Now a days it is important to avoid existing wireless communication networks from the design of UWB antenna. The self complementary UWB antenna impedance bandwidth from 2.9 GHz to 21.5 GHz with a maximum of return loss S11 -43 dB at operating frequency10.5 GHz and with a Gain of 5.64dB.
Keywords: DGS, Impedance Bandwidth, Self Complementary, UWB Antenna.
