The basic motivation behind the choice of ultra wide band based antennas in wireless communication systems is there expedient feeding structure, wide bandwidth along with uncomplicated structure and low cost. Ultra Wideband wireless communication systems are not only serving in enabling applications like wireless monitors, wireless printers and efficient transfer of data from digital electronic devices but this standard is also finding its application in transfer of files among handheld devices such as personal digital assistants and especially for the mobile handsets. With every passing day handheld devices are miniaturizing which has given rise to the need of development of flexible antenna structures. This paper serves to present the design of a two layer monopole antenna with a physically flexible design in order to facilitate the small design and different shapes of the handheld device, under consideration. High frequency structural simulator of Ansoft Corporation has been adopted as the key simulation tool for this design.
