You can download this pdf I wrote few times ago. It is like a basic tutorial, there are a collection of the useful postprocessing things I found on the website. It is written in french but the pictures and the code is enough to understand, check the A.7.4 (and A.7.1) section for the VSWR.

I understand your antenna as a trapezoidal shape. If I'm right, just use a polygon instead of a box https://openems.de/index.php/Polygon.html
Meshing it will be a little more difficult as you won't be able to apply the thirds rule. You can use a high resolution mesh instead.
