Electronic Devices Muhammad Usman Ali Khan 5 2 2016 In this paper we compare the result of Flexible bow Tie Antenna on different wedge angle. For this we used the software CST Micro wave studio. CST Micro wave studio is the advanced software to design antenna in this software after parametric calculation and put these parametric equation in this software than by using sweep parameter option we give the range of the wedge angle (Theta). And compare the result on deferent wedge angle. By increasing wedge angle from a specific limit the wedge of the antenna intersect with balun and result become irregular. To overcome this problem we made the edge of the antenna smooth. And then compare the result of Bow Tie and Smooth Bow Tie.
