I read in the book chapter cross talk in transmission lines "Guard traces have little value in microstrip traces. In stripline, use guard traces with shorting vias on the ends and throughout the length."

How do we short the guard traces ? Short to ground plane through via ?

I still don't understand how could I short both ends of the guard trace through via ? Do you mean GND via ? Short both ends of Guard trace to the Ground plane through via ?
