Abstract

MIMO antenna concepts for electronic eyewear devices operating in 4G cellular standard are proposed in this paper. Coupling element type antennas and matching circuits are used to obtain a high bandwidth potential for the coverage of the 700-960MHz and 1.7-2.7GHz frequency bands. To obtain a dual-antenna MIMO configuration, two CE type antennas are placed on the two sides of the head, resulting in a very high isolation level thanks to the lossy nature of the human tissues (head). It is shown through simulated 3D radiation patterns that very low envelope correlation coefficients are obtained for this placement. Preliminary SAR simulations show values above the 1g standards.
