Which free software is suitable for RF simulation of PCB antennas, allowing me to import my PCB design directly from Fusion 360?
I want to analyze the antenna performance and ideally tune the matching network as well.
Any recommendations?
I doubt very much if there is anything such as simulating an antenna. There are lots of antenna design software packages. Just ask Google.

I have worked with there software in the past and it was very good.
