| Abstract(in English) | In recent years, general methods for predicting and suppressing EMI over a broad band are required. In this paper, an equivalent circuit model for predicting common-mode (CM) radiation from a surface-microstrip line (S-MSL) structure is proposed and demonstrated. The equivalent circuit model is based on consideration of concepts of CM antenna impedance and distributed constant circuit to the conventional mechanisms of current- and voltage-driven. Good agreement between the predicted and measured results shows validity of the equivalent circuit model. The proposed model can predict and explain frequency response of CM current with engineering accuracy, and also express the intermediate state of the current-driven and the voltage-driven. It is demonstrated that outline of the frequency response of EM radiation from the PCB can be predicted up to 5GHz. This study suggests basic method and consideration to establish methods predicting an EM radiation from the PCB. |
