This paper reviews the basic mechanisms through which voltage and current signals in printed circuit boards (PCBs) produce unwanted radiated emissions and some analytical models that can be used to predict these radiated emissions. Three models are applied to a simple PCB and the results are compared to those obtained with the electromagnetic analysis carried out with a Finite-Difference Time- Domain (FDTD) computer code. Although the models are not likely applicable to real-life problems, the comparison is useful to underline their assumptions and limitations.

Abstract

This paper reviews the basic mechanisms through which voltage and current signals in printed circuit boards (PCBs) produce unwanted radiated emissions and some analytical models that can be used to predict these radiated emissions. Three models are applied to a simple PCB and the results are compared to those obtained with the electromagnetic analysis carried out with a Finite-Difference Time- Domain (FDTD) computer code. Although the models are not likely applicable to real-life problems, the comparison is useful to underline their assumptions and limitations.
