Crosstalk - Guard Traces

"To be most effective, the guard trace should be shorted to ground at regular intervals along its length using stitching vias spaced at 1/10th of a wavelength of the highest frequency component of the aggressor’s signal."

Benefits of Coplanar Waveguide Over Ground

"Most RF designers use rules of thumb to space things appropriately. For instance, in microstrip design, many designers use a rule of thumb to keep topside copper away from their microstrip by four times the substrate layer thickness so as to not affect their microstrip impedance. With CPWG you don't have to worry about this since the topside ground is purposefully brought up next to the topside RF trace. But do you have to worry about that close board shield?"

Reduce Anti-Resonance in Decoupling Caps

The anti-resonance occurs at a frequency when one capacitor is still capacitive, while another has become inductive.
