" EMI issues from microstrip are often greatly overstated. The big
offenders on a PCB are: the cavity edges, and the components radiating
above the PCB surface. Doug Smith has some good information on these
types of subjects. Lee is passionate about his practical experience
with M/S and no significant EMI issues."
I was thinking more about the effect of making the surface trace wider
(for lower loss) and further away from the ground plane. I assume that
this increases EMI even though the impedence isn't changing.
