Help needed in HFSS antenna design

Hi,

I have layed out an loop antenna and ran a simulation sweep. I want to know how to extract the inductance of the loop antenna.

I set the frequency to be solved to 434MHz(my desired frequency).

I am getting a inclined straight line for the S parameter. I know that it should dip at 434MHz for it to work properly.

What exitation should i give.

I dont know how to proceeed. Please help me with my design.

Thanks


somebody help me . please reply. i need it for my thesis defense. please
