guess i'll finally have to get into rf circuits and tuning (famous last words). also is there any workable foss 3d fem simulation thing that makes sense for playing with ghz antennas and enclosure geometry/materials? or is this a domain exclusive to expensive proprietary software? are these things even solvable purely in simulation with current computers? can someone just do it for me? :D
i know i can probably buy this as a service from i.e. ezurio but it would be much better to understand more and also being able to share the techniques and insights openly
naively i imagine something like blender but instead of being constrained to visible light it's different EM frequencies

People at work who do research seem to tend to use COMSOL and similar (or their own code) but that's probably going to be way out of your budget and also probably more than you need.
A quick search does find some freeware, no-cost or oss tools for rf design. Edit: such as OpenEMS: https://www.openems.de/
@jannem @mntmn seconding OpenEMS. Kicad 9 brings some niceties to make the process less manual as well. I learned from https://www.youtube.com/@panire3, plenty of examples to get going
