Abstract

In this paper, a novel wearable antenna array backed by an AMC reflector is presented for high gain and low side-lobe levels. The presented antenna consists of a four-element array. The impedance bandwidth (≤ -10 dB) of the proposed antenna is from 5.6 to 6.8 GHz. After adding an AMC structure on the back side of the antenna array, the maximum measured gain reaches 13.8 dBi at 6.7 GHz; the front-to-back ratio (FBR) value is raised by 25.3 dB; and the sidelobe level is less than -20.51 dB. When the antenna array is on the human body model, the simulated SAR value is only 0.05 W/Kg/10 g, significantly lower than the international standard. These good measured results demonstrate that the proposed antenna is suitable for modern wearable applications.
