Comparison of the Parameters of Textile Antennas Manufactured Using Three Techniques: Magnetron Sputtering, Ink-Jet Printing and Embroidery

Abstract

In this work, three textile antennas with the same geometry were produced using three different technologies: magnetron sputtering (PVD), ink-jet printing and embroidery using electroconductive yarn. In all three cases, the electrically conductive medium was the same, which was silver, known for centuries for its very good conductive properties. In order to show how the method of manufacturing antennas affects their operational parameters, the following measurements were carried out: surface resistivity, impedance, standing wave coefficient of antenna radiators, and their radiation characteristics were assessed. The surface resistivity value of the antenna paths obtained ranged from 0.05 to 1.2 Ωm/m.
