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!

Can be so ... !
