Abstract

A motherboard-daughterboard structure with a connector is known to have another source of common-mode radiated emissions, and the emissions depend on the connector's signal/ground pin configuration. In order to estimate the amount of radiated emissions from the structure, a commonmode antenna model is described. The model consists of an excitation source and an antenna element, and it calculates radiated emissions from PCBs not only quickly but accurately for practical use. In modeling the board interconnection via a connector, we added two common-mode excitation sources at each end of the connector. The electromagnetic emissions estimated by the model agreed with the measurements within an error of 6 dB around peak emission levels between 300 and 600 MHz.
