This study presents an artificial magnetic conductor (AMC) design in order to be used for reducing the specific absorption rate (SAR) for the portion of the electromagnetic spectrum in which the electromagnetic pollution is commonly observed. The proposed design has a bandwidth of 0.4609 GHz and it is evaluated by using three different body tissues consisting of planar, cylindrical, and CST SAM phantom head model, and a significant reduction is observed via the usage of AMC. The proposed design, which has an AMC property between 2.8 GHz and 3.3 GHz, achieved a reduction in the SAR value with a percentage of 9% in planar human tissue, 58.9% for the cylindrical tissue, 18.4% for the phantom head model, at 3 GHz. © 2016 Wiley Periodicals, Inc.
