Wearable Antennas for Health Monitoring Systems

Abstract

Abstract: This paper consolidates and synthesizes two detailed IEEE studies on wearable antennas designed for health monitoring systems. The antennas operate at key frequencies in the ISM band (2.3 GHz, 2.4 GHz, and 2.66 GHz), addressing the need for compact, efficient, and safe designs suitable for telemedicine applications. This research explores design methodologies, material considerations, and performance metrics, including return loss, VSWR, gain, and Specific Absorption Rate (SAR). The findings demonstrate the feasibility and practicality of wearable antennas in real-time health monitoring, paving the way for innovations in remote healthcare systems. While conventional copper metal sheets have been used as antenna conductive material. The antenna proposed is designed and simulated using CST simulator, fabricated using flexible copper sheet and tested. On the receiving section the data is collected through the receiving antenna connected to RF module and processed for further analysis of health parameters. A wearable antenna is designed for transmitting and receiving signals at 2.4GHz. A rectangular patch antenna is designed with slots to enhance directivity and good impedance matching with the other RF circuits. The antenna is simulated using Ansys HFSS v19, fabricated and tested which gives a VSWR of 1.5 and Return loss of -14dB.The gain of the antenna is 5.2dB. Further the collected data is visualized and can be analyzed by the supervisor by logging onto the webpage and accessing the health parameters.
