cst plot of impedance's real and imaginary part

hi,
i want to plot frequency v/s real and imaginary part of impedance like in the paper i attached ppt of that fig,but from 1 d results of cst i got complex impedance,i tried template based table application but it give me same plot for real and imaginary impedance,
secondly in the same paper there is a plot between directivty and frequency i tried to make it by broadband frequency in monitor and then using template based application but i am getting a straight line instead of the shape given in fig of this attached paper plz anyone who knows it guide me how can i do all this with cst.
