SAR Reduction of Wearable Antenna Using Multiple Slots and AMC Combination

Abstract

The emergence of wearable and implantable devices has escalated the demand for efficient antenna designs. It has raised public concerns about their safety as the proximity of such devices to the human body during their operation results in highly non uniform radiation exposure. Long-term exposure to such radiation can rupture the tissues and can even cause lethal diseases. As a result, concern about the safety aspects and perilous effects of EM waves is needed. This paper presents a design of a rectangular microstrip patch antenna operating at 2.4 GHz. Two different SAR reduction techniques have been employed for SAR reduction. One is introducing multiple slots in the radiating patch, and the other is using Artificial Magnetic Conductor as a shield. Ansys HFSS has been used for design and simulations. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
