I don't have any numbers or equations to back this up at the moment,
but it would seem that the skin effect loss would be higher than a
msl or sl line due to the fact that current crowding would occur to
cause most of the signal current to flow along the edges of the signal
line in an attempt to get near the return current in the coplanar ground
traces. Same thing for the current in the ground traces, it would crowd
towards the signal line. Since the entire copper surface area isn't being
used for current flow the losses would increase I think.
Anyone know for sure ??
