In this paper we present a modified circular disk nonopole ultra wide band (UWB) antenna. The antenna covers a very large band from 1.5 to more than 15 GHz. The solution of this antenna consists in varying the radius of the patch and the ground dimensions. The proposed antenna designs and performances are analyzed using Ansoft High Frequency Structure Simulator (HFSS). The radiation characteristics are as expected for monopole antennas.
