Hello everybody. I cant create a log-spiral shape in CST. Have anyone this antenna in CST or can you tell me how to create it. I'm really looking forward to the answer.

Its actually super easy.

Can be like this ... !

It does not even in the wildest imagination look like a planar logarithmic spiral. See, for example, http://mathworld.wolfram.com/LogarithmicSpiral.html.
Snails are a better description.

,,,like this...?

Yes, but plananr. Yours is a double helix and you have applied perspective to the design. It will be a lousy antenna, by the way.

Well then, you do not really understand what I mean ....!

Why don't you explain please? I want to know!
