How do I create a spiral Archimedean antenna with custom strip thickness and spacing?

I am trying to create a spiral archimedean antenna with custom strip thickness and spacing using the antenna toolbox. Currently, this functionality is restricted to rectangular spiral antennas. Is there any way to alter the above properties using the antenna mesh or generate one's own mesh using PDE tools? Or would I have to use a CAD tool to design it externally and import it as an STL file?

The Antenna Toolbox catalog supports a spiralArchimedean catalog element. Will that help?
