Investigation on the effect of parasitic inductance at connector contact boundary on electromagnetic radiation

Abstract

A loosened connector causes an increase in electromagnetic radiation when electric devices operate in high-frequency bands. To investigate the mechanisms generating electromagnetic radiation due to a loose contact in a connector, we estimate high-frequency circuit elements at the contact boundary of a loosened connector. On the basis of this estimation, we show the relationship between high-frequency circuit elements and the electromagnetic radiation from electric devices through experiments.
