Abstract
A signal line running between two PCB power/ground planes, with one of the planes having a gap (split), was analyzed using full-wave electromagnetic tools. The gap inductance and the mutual coupling caused by the gap were examined, and distributed effects were observed. As a conclusion, a gap should always be AC-shorted, preferably in the immediate vicinity of critical signal lines
