When I simulate my patch antenna design I get a error like "fast sweep setup process hf3d poor convergence in computing port dispersion"
How can i get correct results for my simulation? I want to design an array antenna(1x4) for 5G as my graduate project. You can give me also recommendations. Thanks..

fast sweep
...
poor convergence
This sounds like you're doing a frequency sweep, correct?
Is it possible you're changing frequencies so fast that the simulation has trouble converging on a stable solution for each timeframe? Which could mean you should slow the sweep.

I understand that I should increase step size for frequency sweep. I will try on it, thank you. It is uncertain that some values of a parameter give me good results without error but some of them also give errors like w70 = 0.1mm is well about convergence but 0.12mm is not.

I don't get any converge error messages.
