what system are you using?

In CADSTAR I would do this by drawing 2 interleaving fork/finger shaped copper shapes and adding a small surface pad on each so I can connect to them, then add a solder resist shape that give clearance for them all.
Also adding a shape on a layer that I would use for carbon coating.
