Body-worn specific absorption rate for MIMO handsets with different antenna setups

Summary, in English

Evaluation of Specific Absorption Rate (SAR) for multiple antenna systems is expected with the upcoming deployment of LTE Advanced, where multi-antennas are excited in both uplink and downlink. In this work, the influence of different antenna locations and antenna types was investigated for stand-alone SAR and simultaneous SAR, to provide some guidelines for antenna design in multi-antenna handsets. For simultaneous SAR, different phase shifts between antenna ports were considered and the averaged SAR was used as a metrics for comparison. The SAR performances were evaluated in the simulation for the body worn scenario (i.e., on the flat phantom), and diffe rent placements of the mobile handset, i.e., with either the screen or back side closer to the body, were studied.
