Abstract :Ultra wide band applications such as medical imaging, surveillance or indoor localization require different bandwidths. The different bandwidth requirements often present a challenge in terms of antenna design. In this paper, a wideband Vivaldi antenna which is suitable for UWB systems is presented. The antenna is designed and optimized using a 3D electromagnetic simulation tool. Then, a parametric study is carried out that investigates the effect of microstrip feed on the antennas bandwidth. It is demonstrated that the bandwidth of the antenna can be manipulated by changing the total length and the positioning of the microstrip feed without the need for changing any other antenna parameter
