Abstract
This paper investigates the effect of grounding posts when printed circuit boards are mounted near and parallel to a metal plate or chassis. Specifically, experimental data showing changes in radiated emission levels are explained by means of coupling phenomena between a power bus, a chassis cavity including grounding posts, and a cable connected to the power bus. This coupling is modeled using SPICE and the results are combined with an equivalent magnetic current source model to estimate the radiated emissions from various printed circuit board configurations. the calculated results are shown to be consistent with the corresponding experimental data. © 2006 IEEE.
