A Vivaldi Antenna For UWB Communication: Design, Modelling and Analysis of Vivaldi Antenna with Genetic Algorithm

Here, the Vivaldi Antenna which is meant for UWB Communication’s has been initiated. The main motives behind this design is to achieve higher gain throughout the range of 3.1 GHz to 10.6 GHz as a result of which it fulfills the criteria’s of UWB antenna for applications in wireless communication. In case of these developments, the author has used Rogers RT 5870 substrate with an epsilon value of 2.33 and simulations been done by FDTD Domain Solver. The initiated antenna displays a gain of 12.27 dBi at highest frequency level along with a constant gain of above 10 dBi from 5 GHz to 12 GHz making it suitable for an X-Band application, to be done as future scope. Genetic Algorithm (GA) is used to carry out, major parametric optimizations which also helped in extending the scopes of operation.
