Abstract [en]

In this paper, we propose a dualband loop MIMO antenna with Wi-Fi 2.4/5.2/5.8 GHz bands for smart watch applications. The antenna is constituted of a 25-mm long folded loop strip and an L-shape coupling strip. Two antenna elements are put at the adjacent side of the ground and are vertical to the system ground. With the coupling strip, the loop antenna can generate a quarter-wavelength resonant mode at about 2.45 GHz and a higher order mode cover 5.2 GHz and 5.8 GHz. The dimension of the system ground is 38mm × 38mm × 0.3mm and a 2mm gap between the antenna and the ground is set to alleviate the strong coupling between the antenna and the ground. The simulation results show the MIMO antenna system have good S11 and S12 performance across 2.4 GHz to 2.5 GHz and 5.2 GHz to 5.8 GHz. Further, as the antenna system is dedicated to be embedded in a smart watch, the body effect and the SAR are also investigated in the research.
