Simulating non-50 ohm port in HFSS and normalization to 50ohm

Hello Everyone;
I am simulating an antenna in HFSS for a chip whose Zin is 15.8-18.6j.For conjugate matching; I should have input impedance of the antenna to be 15.8+18.6j, right?
I am using Driven Terminal solution type in which I have defined the port as follows:
R= 15.8 ohm
X= +18.6 ohm
Is it correct?

Then I am confused; which option should I select from Post Processing tab of the port definition:
"Re normalize all terminals" OR "Don not normalize"

I know the difference between these but I am confused how should I see the impedance matching (better than -10dB) with or without normalization.
Your help will really be appreciated.

Thanks
