HFSS Loop simulation and port setup question

Hello,
I am trying to simulate a simple loop antenna but I am not sure why my the result (current density) does not seem right at all. I am wondering if anyone could help me out and point out where did I set it up wrong.
In addition, I am wondering if anyone could explain me how I should setup the lumped port. Should I just use 50 Ohm or use the resistance I calculated? Should I use the "Negative" value of the inductance I got or the "Negative" value of the capacitance I suppose to use for resonance? And should I normalize the port to 50 ohm?
Many thanks.

Hi,
If you don't normalize, HFSS take the impedance of the antenna to calculate the reflexion S11 coefficient. If you use a 50 Ohms line to feed your antenna, you have to normalize you port to 50 Ohms. The normalization is only an intermediate mathematic tool at the end you must have the real impedance.
I will have a look at your design and i will give you my opinion.
Bye for now
