In this paper, the radiated emission of a microcontroller integrated circuit is investigated by rotating the test board in a transverse electromagnetic (TEM) cell measurement. The dependence of the radiated emission on the angle of rotation is derived on the basis of the coupling between a microstrip line and the TEM cell, and then validated by the multiple-orientation TEM cell measurements in a quantitative accuracy of fitting. With the validated dependence, the radiated emissions contributed by electric and magnetic coupling are extracted. The extracted emissions are found in agreement with the measurement result by near-field scanning experiments.
