Efficient Experimental Assessment of The Specific Absorption Rate (SAR) Induced by MIMO Wireless Communication Devices; Application of Vector Near-Field Measurement System
Résumé
This paper introduces an efficient procedure for the evaluation of the true exposure level, quantified by the peak averaged specific absorption rate (SAR), of multiple-input multiple-output (MIMO) communication devices operating transmission diversity. As compared to the traditional conservative evaluation of the SAR, that results from the unpractical testing of all the antenna-array states of the device, the assessment of the true exposure level enables higher margin for minimizing the SAR while maximizing the radiation performance of the device.
