The result for impedance band width radiation pattern (E field and H field are obtained, to prevent the back radiation a conducting plate was fixed in to the back side of antenna. The gain of the single element was found to be not so good. Good matching is observed over a wide frequency band for single element. The objective of this proposed design model is to compute the far-field pattern and impedance bandwidth of the structure. It is designed for wideband application Design methodology consist is to divide the Vivaldi antenna into two parts i) microstrip-to-SIW transition ii) tapered curve part. CST software (microwave studio suit) was used for simulation and optimization in Time domain analysis. We have designed a Vivaldi antenna with microstrip to SIW feed different parameters are studied and analyse. The Vivaldi antenna is one type of planer antenna having the property of easy design, lower cost with light weight. Over the last two decades, tapered Slot antenna have effective performance for wideband applications.
