Ultra-wideband (UWB) printed antenna having a disc-shaped radiator fed with a co-planar waveguide (CPW) is shown in this paper. A modified ground plane is initiated to observe the behavior of UWB bandwidth. The dimension of the proposed antenna is 20 X 25 X 1. 6mm3 . Comparing the prototype conventional printed antenna with reducing the ground plane in both length and breadth of the ground plane one by one. From the graph of return loss, voltage standing wave ratio (VSWR), radiation pattern that is best suited for optimized dimension can able be detected. The best parameters for UWB antenna are the fractional bandwidth which should be more than 85%, and VSWR, another parameter. The range of bandwidth of UWB must be below 2 for the best and most effective way of printing monopole antenna. Results show that the length and width of the ground plane are 15.9 mm and 11.4mm, which is most appropriate for UWB since it gives a return loss of -41.86 dB, a fractional bandwidth of about 89% and VSWR of below 2 within the frequency bandwidth. A fair radiation pattern which is omni-directional in nature, is observed in this modified prototype antenna.
