Measurement of Electrophysical Properties of Fabric Materials and Their Use in the Implementation of Antennas

This paper describes a variant of measuring the properties of fabric materials for designing antennas on them. To measure the dielectric constant of cotton with a thickness of 1 mm using waveguides. Antenna design was carried out using Ansys HFSS. Systems on flexible substrates (fabrics, films, etc.) require the use of low-profile, with low weight and dimensions, as well as resistant to bending.
