Hello. I'm looking for literature or explicit formula about calculation of copper clad stub (impedance adapter) with a shape of rectangular triangle for use at output of an helix antenna.

What's a "rectangular triangle"? :smile:

And the stub match section doesn't need to be copper coated for some reason, does it? It only needs to be conductive, I would think.

Can you post pictures or diagrams of what you are asking about? Stub matching is a pretty well-documented technique, IMO...
 
Sorry for my poor english ... It's a triangle with a 90° angle ! Iguess copper is for having a good conductivity.
