Design and Development of Rectangular Patch Antenna for Health Care Application using ISM Band

Abstract

This paper presents the design and implementation of an antenna for patient health monitoring system integrated with a compact micro-strip patch antenna embedded inside a wearable watch. The proposed system continuously monitors vital parameters such as body temperature, heart rate, etc., using biomedical sensors, and transmits the data wireless through a 2.4 GHz antenna. The antenna was designed using CST software and later fabricated on an FR-4 substrate. The fabricated prototype was tested using a Vector Network Analyzer to validate the simulated results. The simulation and experimental results demonstrate close agreement, confirming the reliability and feasibility of the proposed system for real-time healthcare applications.
