It combines conductive fabric, used as the radiator, with polydimethylsiloxane (PDMS) utilized as the substrate as well as the encapsulation of the antenna. The mechanical and electrical characteristics of PDMS-embedded conductive fabric structures are firstly investigated, followed by the general steps of the antenna fabrication process. As concept demonstrations, two designs, dual-band dual-mode and frequency-reconfigurable patch antennas, have been fabricated. Experimental investigations on the antennas' RF performance (both in free space and on a muscle phantom) and mechanical stability are also demonstrated. The latter includes bending on human's arm-shaped phantom and machine-washing tests. The results demonstrated that the proposed method is applicable for realization of robust, flexible, not only passive but also active, wearable antennas.
