Modeling and Analysis of an Efficient Bow-Tie Antenna for UWB Applications

UWB Communication Systems have recently attracted considerable research effort for their potential advantages of high data rate and low energy density. As one of the key components of an UWB system antennas with wide impedance bandwidth, stable gain and VSWR are required. Bow-Tie antenna is a good choice of UWB antennas. In this paper a Bow-Tie antenna is designed and modeled by using WIPL-D for a wide frequency range (3.1 to 10.6 GHz). The general characteristics of the antenna such as Gain, Impedance and VSWR are analyzed.
