Real-time tracking, together with monitoring and data collection of human body signals, happens through RFID technology amalgamated with wearable electronics called wearable RFID sensors. Modern sensors find placement in clothing items as well as accessories, and they also operate beneath the skin. The sensors serve several applications across healthcare monitoring, together with asset tracking and security system functions. This article delivers an extensive examination of body-area RFID antenna design issues regarding operating frequencies with biological tissue effects and antenna performance, together with safety compliance aspects. A multicomponent antenna system works as an RFID shield and functions for Bluetooth along with Wi-Fi (2.4 GHz), and includes temperature and sweat sensors for healthcare distance monitoring. The designed antenna spans 600 MHz (2.2–2.8 GHz) within its 25 × 40 × 1.5 mm 3 dimensions. This antenna finds optimal application in wearable systems because it utilizes semi-flexible Rogers RT5880 substrate material. The system obtains miniaturized dimensions through the implementation of two E-shaped slots, which allow the device to operate in the desired frequency range. Stability characteristics allow the antenna to operate properly near human bodies and meet the SAR safety requirements of 1.6 W/kg at its operating frequency. Realistic performance tests produced efficient results close agreement between simulated and measured data, thus validating the design potential as a remote healthcare monitoring solution.
