Measurement of Shielding Effectiveness in Coaxial Cables and Connectors With Various Dielectrics Using an Electric Field Probe
Ensuring proper shielding is essential for the electromagnetic compatibility of electronic devices and systems. This article investigates the shielding effectiveness of coaxial cables and connectors using an electric field probe. The study aims to identify shielding failures early to prevent costly fixes later. A method for measuring the electric field radiated by connectors and cables in both near-field and far-field conditions is presented. Additionally, an electromagnetic virtual model of the connector and cable was developed, incorporating the dimensions and properties of the dielectric material. The simulations focused on the impact of different dielectrics on the resonant frequency of the electric field, specifically common-mode energy. The results showed that the dielectric properties do not affect the resonant frequency in the presence of a common-mode current distribution.
