Measurement of Broadband Dielectric Properties of Textile Fabrics for Clothing Antennas

A broadband
$\boldsymbol{(0.5\sim 20 \text{GHz})}$
dielectric characteri-zation of textile materials for clothing antennas is presented in this paper. The dielectric properties of four types of textile fabrics were investigated, where the measurements of complex permittivity were undertaken using open-ended coaxial probe. Frequency dispersion of these properties over 20 GHz were studied with standard deviations.
