antenna impedance in hfss

[naumanhbk]

hi all!

guys is there any one who knows about measuring impedance of an antenna designed on hfss. this is probably through smith chart. i dont know how the impedance can be interpeted using this as smith chart shows many circles and some thing strange like a circle which is having many turns around the starting point.

if anyone knows plz help...
thanx

If its a port then the impedance will already be calculated, and the results should be under Analysis->Setup_name then right click and matrix data.

for eg: if 3 times circle round that means 3 resonance of frequency will occur.

Under results, the Z-parameter give the impedance values.
