Two questions that has always bothered me...
1) volker_muehlhaus and others has shown em plots where the current/field rapidly decreases as we move away from the narrow slot, (https://www.edaboard.com/threads/254994/). I've seen this also in sonnet. From an isolation perspective, is it better to have two narrow grounds (>1.5*w) or one much wider ground between two RF traces?
2) If using grounded coplanar, is the straps over the strip necessary?
I'm working on a 500 - 3GHz switch. The current dream is 4350 w=30mil, s=10mil, h=20mil.
tnx,
Gene
