Flexible and Wearable Antenna Design for Bluetooth and Wi-Fi Application

Abstract

The emergence of wearable technology has revolutionized the way we interact with electronic devices, integrating them into our daily routines. From fitness trackers, smart watches to augmented reality glasses and medical monitoring devices, wearable have become increasingly prevalent. Among the most commonly employed wireless technologies within wearables are Bluetooth and Wi-Fi. The design of efficient and reliable antennas for Bluetooth and Wi-Fi applications in wearable is of paramount importance to ensure optimal performance and user satisfaction. In this paper presented a flexible and wearable antenna design for Bluetooth and Wi-Fi application utilizing the Rogers RT5880 flexible substrate, characterized by a dielectric constant of 2.2 and a thickness of 20mil. The study delves into various analyses of the antenna, including its performance concerning on-body and off-body communication, along with an exploration of the antenna's response to different bending effects. Moreover, the research investigates how the antenna interacts with a human tissue model, providing insights into its behavior and performance in diverse usage scenarios.
