Abstract: A CPW fed novel compact Ultra wide band antenna is proposed in this paper. The size of the antenna is 20mm x 20mm x 0.6mm and it is prototyped on FR4-Epoxy substrate material which has a dielectric constant of 4.4. The proposed antenna provides a bandwidth of 5.45 GHz from 4.76 GHz to 10.21 GHz which can be used for wireless applications. A parametric study is carried out by varying the horizontal and vertical gaps ‘g’ and ‘d’ between the conducting patch and ground. The output parameters and the dimensional variation effects on the proposed antenna are presented in this paper. Simulations are carried out using Finite Element based Ansoft High Frequency Structure Simulator.
