Re: Radiation boundary problem in HFSS with antenna simulati
I ran your file and the results are as shown. You can see the impedance
and the return loss are good but the radiation are bad.
This happened to me when the dimensions of the radiation box are small
with respect to the frequency. I did not do a redimensioning so far, but all I can
say is that HFSS is famous for this problem, for low frequencies the dimensions
become so big that it takes a long time to simulate, that is way I have not tried
yet.
