Finally, the selection of the fabric material is also of great importance. Moreover, the literature suggests that (c) embroidered patch antennas, due to low-cost automatic embroidery machines that operate with conductive yarns, are highly popular. Additional factors were also considered herein that ensure stable antenna characteristics, such as (a) the antenna, combined with the supporting structure must be sufficiently flexible, but not drainable, (b) layouts are to be protected against stress and crumbling. Additionally, according to, operations such as washing and ironing are key aspects of antenna robustness. discuss several challenges of wearable antennas among them, major ones are technology invisibility to the user and similar wearability guarantee of conventional clothes. Īlthough the aforementioned designs are easy to implement from a geometrical point of view, various restrictions should be taken into account prior to computer aided design (CAD) and manufacturing procedures. This particular problem concerning textile antenna ( textenna) manufacturing is the main focus of. On the other hand, flexible antennas can easily be worn by a human body, which naturally moves, causing clothing deformation however, such radiating structures are much more difficult to incorporate to a garment. A wider variety of rigid antenna designs may be found in. Typical rigid structures are used for off-body radio links, such as in smart watches and life jackets, or even on-body configurations, firmly attached to the garment, such as in a military badge. On the basis of their functionality and structure, wearable antennas may be categorized into two generic types: rigid and flexible. Actual products based on this particular technology range from biometric insoles and interactive belts to connected T-shirts and Bluetooth jewelry. Hundreds of articles have been published in the literature, and a comprehensive review discussing all aspects of wearable antenna applicability is presented in. Wearable antennas have been a topic of interest for more than a decade, with applications of a very broad scope, including security, health, sports, communications, glamor, etc. ![]()
