Abstract:

In order to study the shielding effectiveness of multilayer electromagnetic shielding fabric, by changing laminated angle, spacing, laminated methods and number of layers, double and multilayer electromagnetic shielding fabric with orthogonal conductive grid structure and parallel structure of metal fiber yarns in single direction were built. The flange coaxial method was used to test the shielding effectiveness of the fabric in 0.3 ~ 1.5 GHz. According to the results, for the fabric with the same warp and weft and metal yarn spacing, shielding effectiveness of double-layer fabric is obviously higher than single layer fabric when shielding layer thickness is less than skin depth. Beyond the skin depth, increases of shielding effectiveness are not significant. The shielding effectiveness of three or more layers fabric is no longer significantly increased. And the shielding effectiveness increases with the increase of interlayer spacing. For the double fabric composed of single fabric containing metal fiber yarn in only weft direction, the shielding effectiveness increases with the increase of weft yarn cross angle. Moreover, with the increase of interlayer spacing, the shielding effectiveness increases when weft yarn is stacked horizontally in double fabric, and decreases when stacked vertically.
