Objectives: In this digital era, Ultra Wideband (UWB) is an emerging technology and it has numerous applications in different fields. The frequency of UWB ranges as 3.1GHz – 10.6GHz and some narrow band applications also exist which causes interference to Ultra band applications. The miniaturized antenna with CO shaped radiating antenna element pattern for Ultra Wideband applications is proposed in this paper. Methods/Statistical Analysis: The micro strip coplanar fed line technique through the ground plane is used to nosh the antenna with 50Ω impedance. The proposed micro strip patch antenna is designed using Teflon dielectric substrate material which has a conducting surface on another side. The polytetrafluoroethylene or PTFE which is also known as Teflon is a high flexible, electrically resistant material and shows better resistance to water. Findings: The proposed antenna made up of Teflon substrate material with the dimension of 20mm X 20mm and CO shaped radiating patch with micro strip feed line having the dimension of 7mm X 0.5mm. The power loss in the signal returned in the transmission line is -20.36dB the miniaturized micro strip patch antenna operates at the frequency of 10.3GHz. The gain attainment is 3.7dBi. The proposed antenna applications are in Military areas, Medical imaging and Medical Monitoring.
