Abstract
This article describes a methodology to predict radiated emission from the printed circuit boards (PCBs) excited by switching noise of integrated circuits (ICs). Radiation characteristics of PCBs were simulated by using commercial 3D full‐wave softwares. IC's switching noise was obtained by measurement. The radiated emission can be calculated by these two factors. To verify the calculation, test PCBs composed of power and ground plane were designed and measured in a 3 m semi‐anechoic chamber. The calculated radiated emission showed a good agreement with the measured results. © 2009 Wiley Periodicals, Inc.
