Radiation noise from the electronic equipment is controlled by the standards such as FCC, VDE, VCCI and so on, and noise reduction is very important for the manufacturers. Printed wiring board (PWB) is the noise source of the radiation. So studying the generation mechanism of the radiation and reducing it on the PWB level is most effective for the noise reduction. We have aimed the estimation of the radiation from the PWB by calculating the radiations from each patterns on the PWB and integrated them. In this report, the calculation techniques of the radiation from single pattern on the PWB is shown. The radiation depends on the common mode current, in this experiments, and is calculated from the common mode current by using simple equation. The calculated results are compared to the experiments and good qualitative agreements are obtained.
