I installed Ansys-HFSS today and try to made some simulation result. It proves that Ansoft is a excellent software for solving electromagnetic field during antenna design. This is a rough try, we still have a lot to do, by saying a lot to do, I mean simulation, antenna configuration design beforehand, etc. Ansoft produces vectorial figure, meaning you can enlarge these pictures without losing high resolution (dpi).
