Abstract

Shielding effectiveness is a major problem to prevent electronic products from emission and radiation. This paper is written to present the measurement of shielding effectiveness (SE) and S21 for such enclosure at frequencies below 1GHz. The measurement results indicate that a wire or cable penetrating into an enclosure has impact to the shielding effectiveness. The coupling between a wire penetration and a detector inside the enclosure show good agreement between experiment and simulation. The different length and direction of a wire penetration were used to interpret the theory. All results indicate the same resonant frequency approximately 707.1MHz for a 300 x 120 x 300 mm enclosure.
