Can I simulate an antenna by using HFSS when its working frequency is some lower.(e.g.30MHz)
I mean that when the work frequency is 30MHz, whether the simulation accuracy of HFSS still can be assured?
Thanks a lot
You helped me a lot, Peter, I really appreciated it.
The antenna is narrowband and expected to work at 30MHz, so the efficiency is more important.
I will looking for the antenna you provide me and consider which will be the better one.

electrically small structure
Recently, I engaged in designing an electrically small antenna with input impedance of 50Ω and the working frequency is 30MHz.
The length of the antenna is expected to be about 30cm, I tried TEM horn but found the S11 is too poor.
Is there anybody who can provide...
Thanks a lot.
I have another question, you know that when simulating antenna in HFSS, we need to set a radiation boundary(e.g. A air box enclosing the radiation objects). The lumped port set in the air box will contact the air on one side and contact the radiation object(e.g. TEM antenna) on...
I'm confused by a problem these days and I hope that you can help me.
I want to investigate the return loss of a TEM horn by using HFSS, while the impedance of the feeding line is supposed to be 50Ω.
Do I need to describe the concrete feeding structure in HFSS when doing...
