Prediction of the common-mode radiated emission from the board to board interconnection through common-mode antenna model

In this paper, the common-mode antenna model, which can estimate the amount of common-mode radiation quickly and accurately, was applied to a board-to-board interconnection structure with a connector. The inductor model is introduced as the connector model for improving accuracy of the common-mode antenna model. By using the inductance, which was calculated with the commercial electromagnetic field simulator, the radiated emissions estimated by the model agreed with the measurement results within an error of 3 dB around the peak emission levels.
