HFSS Planar Spiral Inductor

Hello Everyone,

I am trying to model a 6 turn spiral inductor (rectangular) in an air box. I was wondering if anyone could have a look at it and see why I am getting no value for the structures inductance and very little resistance.

Predicted Values from using other s/w / experimental:

Inductance at 1 MHz should be around 730 nH
Resistance at 1 Mhz should be around 0.2 Ohms

I have excited it using a lumped port.


I have attached the HFSS file. Any advice is much appreciated

Originally, I would like to simulate your structure, however, I think I didn't grasp your idea completely, so here I just raised some questions and/or suggestions. Hope you have already solved this problem.
My comments:
1) The integration line setup of the lumped port is strange, should it be along the middle line of the spiral conductor?
2) What's your boundary? According to HFSS fullbook, a radiation boundary is needed, but you just set a remote gnd, which is also weird.
if you have succeeded at this, may you provide some feedback here?
