Since the United Sate Federal Communication Commission (FCC) released the first Ultra
Wide-band (UWB) report on February 14, 2002, the interest in UWB technology has
increased substantially in both academia and industry. Interest is to simulate by the
expectation that UWB can solve the shortage of the available frequency recourses.

This paper demonstrates the comparative analysis of the performances of two antenna designs, half wavelength Wireless Local Area Network (WLAN) patch antenna and a broadband Ultra wideband (UWB) monopole antenna. Both the antenna designs have been simulated utilizing the Advanced Design System (ADS) tools. During the investigations, it has been observed that the low profile antenna with its wide impedance bandwidth, quasi-Omni directional radiation pattern and high efficiency is quite promising for the existing communication and surgical instruments. In this work, we have simulated and measured the different essential parameters such as input reflection; voltage standing wave ratio (VSWR), radiation pattern, simulated current distributions and the efficiency of the proposed designs are also presented and analyzed. Measured results were taken using a Vector Network Analyzer (VNA).
Abstract— 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.
