Novel Flexible and Wearable 2.4 GHz Antenna for Body-Centric Applications

Abstract

Novel flexible and wearable antenna for remote health monitoring is presented. The patch antenna simulated to operate at 2.4 GHz frequency for ISM band applications. The proposed design was fabricated using polyimide as a substrate, which is flexible, efficient, low-profile and suited for wearable applications. The performance of the proposed wearable antenna has been experimentally studied to evaluate the mechanical bending and human body effects. The antenna can operate under significantly bending angle and body effects attributed to its broad operating bandwidth. The simulated results show high radiation efficiency about 90% both in free space and near the vicinity of the human body. The performance of the antenna is susceptible to numerous potential applications such as information exchange, personal security, health monitoring.
