Wearable Full-Textile Spoof Surface Plasmon Polariton Transmission Line for Secured Communication in Wireless Body Area Network

AbstractIn this article, a wearable full-textile spoof surface plasmon polariton transmission line (SSPP TL) with improved communication data security has been presented. Equivalent circuit analyses reveal that the new proposed SSPP TL based on the patch-loading technique achieves flexible dispersion control by changing the patch dimension. As compared to conventional SSPP TL with periodical corrugations, the proposed wearable SSPP TL has similar transmission performance, but with a 43% reduction in transversal width. Such results are beneficial to the size reduction of the wearable wireless body area network (WBAN) system. Besides, the proposed SSPP TL achieves stricter field confinement, which helps to improve communication data security. The proposed wearable SSPP TL is pattered by hand-cutting the conductive E-textile. The feasibility of the wearable SSPP TL has been verified through the S-parameter simulation, specific absorption rate (SAR) simulation, the measurement in the free space, and measurements on different mounting positions of the human body.
