Abstract

A multilayered Artificial Magnetic Conductor (AMC) antenna is proposed in this article for medical body area network band. The AMC comprises a 2 × 2 array of rectangular unit-elements which provides a zero reflection phase. The AMC is placed below the circular monopole antenna to increase the gain and reduce the backward electromagnetic radiations. The operating frequency band ranges from 1.9 to 2.44 GHz. The incorporation of the AMC lowers the average 1-g SAR to 0.675 W/kg at the specific band of the flat antenna when it is 1 mm away from the antenna. The proposed antenna gives peak antenna gain of 4.2 dB, and front to back radiation ratio of 8.94 dB at 2.23 GHz.
