smith chart cst

plz help me
tell me how can we plot input impedence of an antenna on smith chart in CST Microwave studio.

Hi,

i think, that is impossible, in the help is sentence:
"Smith Charts are defined only for reflection parameters (S11, S22 etc). Therefore, only these values are plotted."

you can only calculations Z and Y matrices: Results - S-parametr calculations - calculate Z and Y matrices, but is only 1D results

thank you
is there any other option to draw the smith chart of input impedance of antenna?
