Hi All,
I am not sure what would be better. In the case that we have a one single layer PCB what would be more advantageous for EMC?. Would we prefer to create a ground plane that would contribute to less inductive impedance at high frequencies but on the other hand it could create current loops, or would we prefer to have two power rails, one for VCC and another one for GND to put close those rails to benefit from cancelation but on the other hand in this case the inductive impedance would be higher.
If we decide not to have a ground plane ( so to have two power rails), filling the board with copper ( unconnected to any potential) would give us a benefit?.
Thanks in advance,
Winsu.
