Coaxially Fed Spiral Antenna in HFSS

Hello All,
I am trying to simulate a simple spiral antenna in HFSS. I have attached the simulation file.
I am using the following project variables to control the spiral geometry:
Sa - spiral constant (mm/radians)
St - spiral arm width (mm)
Sphi_seg1_stop - total angle circumscribed by the spiral (radians)
The problem is, I do not get any different results for different values of these constants. For e.g., I keep getting the same S11 plots.
My guess is that I have made an error in the setup of the excitation.
Could someone please help me with this. Thanks a million in advance.

Hey
Which spiral have u made? Archmedean or Equiangular (logarthmic)?
