Re: Ensemble Tutorial
You are facing the same problem as myself about two years ago.
Despite my best efforts, I had never found any official tutorial for Ansoft Ensemble
regarding the microstrip lines, only for the planar antennas and filters.
It is however reasonably simple and quick, thanks to MoM, so it runs much faster
than HFSS.
Start with drawing single mircrstrip line on a first metal layer. Use the provided microstrip calculator, add the ports and solve. There is no settings for a coupled ports, so finding differential parameters could be an issue.
Generaly speaking, use HFSS, it is more memory hungry, but you can solve vias and similar discontinuities.
