Abstract
Radiated emission due to common mode current is usually dominant in total emission. The common mode current is generated when the ground width of the microstrip structure is narrow. A procedure is proposed to predict common mode current from normal mode voltage at a point where cross-sectional structure is varying. As a result, the predicted spectrum and distribution of common mode current agree well with measured data
