zigzag shaped spiral Antenna- CST (Store Picked Point)

Hello everybody;
I want to design a zigzag-shaped Archimedean spiral antenna with CST (2011), I know how to design the normal one by the mean of "analytical curve or face", but I don't know how to change the shape of its arms to zigzag, rectangular or even triangular shape...

I want also to taper the outermost arms in order to reduce current reflections...
Becoz I'm interested in the miniaturization, I would also load the ends of arms by resistive loading, but can't do it :(

I'm new in CST so if anyone can help me I'll be thankful ;)

[by the way I found in some CST template projects this one "store picked points" in the history list, I really need this option but I don't know where to find it in CST]

regards.
