Simple compact Ultra Wide Band (UWB) Vivaldi Tapered Slot Antenna (VTSA) is presented in this paper. Detailed parametric studies are performed to get good performance with a compact size. The proposed antenna shows good impedance matching less than −11.283 dB through 3.325 GHz–10.82 GHz. Although of its compact size (43.92 mm × 35.32 mm) and not using any gain enhancement technique, the antenna provides a high maximum gain of 7.63 dBi. The proposed antenna with compact size, end-fire radiation pattern, wide bandwidth, and high gain makes it suitable for UWB communication systems applications such as remote sensing and through-wall detection. The simulation in this paper is carried out using Computer Simulation Technology (CST) software which is based on Finite Integration Technique (FIT).
