Abstract: In this article, a triangular patchtextile antenna has been proposed for health monitoring systems. The patch is fabricated using copper tape and substrate is made up of cotton. Two slots have been introduced near feedline to get larger the bandwidth.The size of the proposed antenna is 90×80 mm². The textile antenna is powered throughmicrostripfeedline structure. The antenna resonates at ISM band of 2.4GHz. The antenna provides a peak gainof3.15 dBi and radiation efficiency of 81.33% over the resonating frequency. The impacts on human head and handof electromagnetic radiation are evaluated. The electromagnetic radiation is evaluated usingSpecific absorption rate at different distances from human head and hand. The antenna parameters like radiation efficiency, radiation pattern, return loss and directivity have been evaluated. The antenna is designed and simulated using ANSYS High frequency structure simulator(HFSS) software and the fabricated prototype antenna is tested using network analyser.
