Abstract
In this paper, a compact MIMO(Multiple Input Multiple Output) antenna for smart glasses is proposed. The proposed MIMO antenna is designed using T-shaped isolator inserted between two closely located Inverted-F Antenna(IFA) and using two slots located in the ground for isolation enhancement and impedance matching characteristic. The proposed antenna has only the overall dimensions of $35mm{\times}9mm{\times}0.8mm$ and operates in the 2.4 GHz industrial, scientific, and medical(ISM) band. To verify human body effect, the phantom is used for antenna performance. The measured specific absorption rate(SAR) value is 1.38 W/kg with an input power of 18 dBm. The performance of the proposed antenna is compared with that of previous works for verification.
