Abstract
A dual-band MIMO antenna is proposed on the basis of artificial magnetic conductors (AMC). The MIMO antenna consists of two water lily shaped printed monopole antennas and an SRR isolation structure, operating at the ISM bands of 2.45GHz and 5.8GHz.A simple, compact double circle-based artificial magnetic conductor (AMC) reflector is introduced to decrease radiation exposure to people as well as increase forward gain. The antenna and the 4x4 AMC array are both printed on flexible substrate Rogers RO3003, thus the antenna system can follow the contours of the human body. According to the simulated results, the proposed antenna exhibits peak gains of 8.03 dBi and 8.43 dBi at 2.45GHz and 5.8GHz respectively. The SAR value of body tissue can be reduced by around 97% while the front-to-back ratio (FBR) is over 24.5dB. Its improved radiation characteristics compared to conventional monopole antennas make it a good candidate for WBAN and ISM applications.
