Thanks, but there's one thing that I can't find anywhere: how can I calculate Vivaldi antenna input impedance? I also found a dielectric transformer (Characterization of miniature millimetre-wave vivaldi antenna for local multipoint distribution service, Simons, Lee), but I don't understand how it works and what are its dimensions (in general, not just for a specific antenna).

I also want to simulate vivaldi antenna, and I will the finite element method with my own algorithm.
but the most difficult task for me is to geometry modeling and mesh genernation.

would anyone give me some advice ? thanks !

EMC Studio: Vivaldi Antenna Example

You can try Method of Moments software for numerical simulation reference. Attaches is planar-triangular meshed Nastran file with this antenna.
