High Gain Ultra wide band Vivaldi antenna with a single array tapered slot Vivaldi antenna element designed, fabricated and validated in this research at a 2.4 GHz frequency. The Gain of the fabricated antenna remain constant with the change in frequency. In practically the alteration from micro strip to slot line in this research design limits the further extension of impedance bandwidth. A minor change in the construction of this antenna is done to overcome this disadvantage by limiting factor of the antenna is made to achieve the required bandwidth. The frequency and power gain can be increased by multiple combination of this array as the feed forward antenna. The VSWR is a measure of efficiency of transmission from a power source to the receiver in a desired direction. VSWR helps in measuring the voltage adjustments. The voltage doesn't differ in a perfect system and its VSWR is 1.0. The fabricated tapered slot Vivaldi antenna using FR4 material. This fabricated antenna can be used for see through wall and recuse applications, which is test by single antenna parameter and verify the desirability of the antenna for UWB systems for see through wall applications.
