Abstract
In this paper, stainless steel core yarn was selected as a conductive yarn to produce conductive fabrics. The electromagnetic shielding effectiveness of twill and some diced woven fabrics with different metal densities were measured by free space measurement technique at horizontal polarization of the antenna. It was found that woven fabric samples shielded well in high frequency band, namely industrial, scientific and medical band. The electromagnetic shielding effectiveness of fabric samples woven increased in accordance with the steel core yarn density in high frequency band if the fabric samples were positioned so that the weft yarns were vertical to the antenna polarization. When the effective surface conductivity increased, the decrease in the electromagnetic shielding effectiveness of woven fabric samples, which were positioned so that the weft yarns were parallel to the antenna polarization, was observed, adversely.
