Abstract

This article tests Specific Absorption Rate (SAR) reduction in WBAN square patch antennas using various types of AMC structures. The AMC structure is designed. The AMC structure can reduce surface waves and prevent unwanted radiation from the ground surface. Thus, the AMC structure designed for WBANs allows you to adhere to exposure guidelines. Simulations and measurements show a reduction in radiation patterns and SAR values towards the human head. In addition, AMC increased the FBR by 15.3 dB, gained 7.61 dBi and radiation efficiency exceeded 88%. AMC achieved a 93.7% reduction from the initial SAR value, while metal reflectors achieved a 77.7% reduction. Then, the antenna is fabricated and measured to validate the concept.
