Abstract:

Recently, there has been a burgeoning demand for wireless health monitoring systems employing flexible wearable antennas to facilitate seamless communication between individuals and their healthcare providers. The principal objective of this scholarly investigation revolves around assessing the operational efficiency of an economically viable, fabric-based flexible wearable antenna design meticulously fashioned on denim, with a specific focus on its applicability in wireless health monitoring. The significant feature of this antenna is its minimal physical size, measuring 50 mm × 35 mm × 1.0 mm, and it also draws attention as an antenna with excellent performance, boasting high efficiencies of approximately 96.7% at 2.44 GHz and 96.2% at 7.66 GHz. It exhibits commendable attributes in high gain and directivity, quantified at 4.32 dBi and 4.87 dBi, respectively, at a frequency of 7.66 GHz. The pivotal highlights of this ultra-wideband (UWB) antenna encompass its compact form factor, lightweight construction, cost-effectiveness, inherent flexibility, straightforward fabrication process, and seamless integration into clothing. These distinctive attributes underscore its suitability as a wearable human body antenna tailor-made for deployment within wireless body area network (WBAN) systems. Notably, both the simulation and measurement outcomes of the abovementioned antenna design corroborate its preeminence and suitability for WBAN applications, particularly in the context of ultra-wideband operations.
