On simple one- or two-layer PCBs, loops are formed by the logic signals being transferred from one device to another that return by means of the power distribution rails. Loops are also created by PCB traces or rails that supply power to these devices. Common-mode radiation results from voltage drops in the system that create common-mode potential with respect to grounding. In addition, parasitic capacitive coupling, a hard-to-control phenomenon that occurs between all conductive materials, makes external cables act like antennas.
