Recent Advancements in Modern Antenna Design for Wearable Devices

Abstract

The rapid growth of wearable technologies within wireless body area networks (WBANs) has increased the demand for advanced wearable antennas. The human body's presence creates significant challenges for these antennas since it behaves differently as a wave propagation medium. It is necessary to prioritize specific requirements for antenna design, such as size, frequency, efficiency, wideband and multiband operation, because of body interaction and signal attenuation. The development of novel methodologies, the use of state-of-the-art fabrication methods, and the advancement of antenna designs have been the main areas of attention for researchers in this field in recent years. This research investigates contemporary advancements in wearable antennas, particularly emphasizing utilizing recent materials, fabrication processes, and new techniques. It also highlights the unique applicability of these antennas in advanced WBAN systems.
