Experimental Shielding Effectiveness Analysis of Metal Plate Influence inside an Enclosure with Aperture

摘要

This paper considers the experimental shielding effectiveness analysis of an enclosure with a metal plate placed at a certain angle inside. Dimensions of a metal plate are determined to affect the enclosure’s first resonant frequency in order to improve its protective function. A metal plate impact inside measured enclosure on the shielding effectiveness values especially at the first frequency as well as at the whole frequency range is presented.
