Dear Ashfaq Ohi ,

you can find the design equations of Vivaldi antenna in the attached references.

[1] P. J. Gibson, “The Vivaldi Aerial”, in Proc. 9th European Microwave Conference, Brighton, U.K., June 1979, pp. 101 – 105.

[2] Microstrip Antenna Design Handbook -Artech House Publishers (2001)P. Bhartia, Inder Bahl, R. Garg, A. Ittipiboon .

Regards.

Jafar Norolahi

first study the reff that @ Ahmed Sayed introduced then refer to mathworks file exchanges.

Nirmala Mattaparthi

you can find the design equations in the references of linked paper
