Guys I have a problem when designing a vivaldi antenna that operates from 1 GHz to 28 GHz in cst.
I have red many posts about the vivaldi on edaboard, however I have tried to use the spline but don't know how to implement the exponential for tapers.
If anyone have a solution please don't hesitate to give me, or if anyone could send to me the design from "antenna magus" with the frequency mentioned above I would be thanfull.
