Abstract / Description of output

A flexible textile-based coaxial transmission line for wearable applications is presented. The textile material, polytetrafluoroethylene (PTFE), was used to design the prototype. The performance of this RF cable was simulated and measured, and it is operational to about 6 GHz. The performance of the prototype was also measured under wet conditions. Furthermore, an electromagnetic coupling analysis, was performed, which evaluated the shielding effectiveness of the cable. When compared to a more standard coaxial cable, a mass reduction of about 30% was achieved for the developed textile-based cable. The highly flexible nature of the cable makes it suitable to use with wearable antennas and other RF components for various on body sensors and communication systems. Moreover, it can also be fully integrated and positioned discretely within different garments. Example placements include along the arm, hood, or chest. To the best knowledge of the authors, no similar textile-based transmission line has been demonstrated which offers 50-Omega connectivity.
