Este artigo propõe e verifica um procedimento específico de medição de taxa de absorção (SAR) para transmissores multiantenas que requer medição de distribuições bidimensionais de campo elétrico para o número de antenas e cálculo para obter as distribuições tridimensionais de SAR para coeficientes de ponderação arbitrários. das antenas antes de determinar o SAR médio. O procedimento proposto é verificado com base no cálculo e medição no domínio do tempo de diferenças finitas (FDTD) usando sondas eletro-ópticas (EO). Para dois dipolos de referência, as diferenças no SAR de 10 g obtido com base no procedimento proposto comparado numericamente e experimentalmente com aquele baseado na distribuição SAR tridimensional original calculada são no máximo 4.8% e 3.6%, respectivamente, em 1950 MHz. Em 3500 MHz essa diferença é de no máximo 5.2% na verificação numérica.

Abstract: This paper proposes and verifies a specific absorption rate (SAR) measurement procedure for multi-antenna transmitters that requires measurement of two-dimensional electric field distributions for the number of antennas and calculation in order to obtain the three-dimensional SAR distributions for arbitrary weighting coefficients of the antennas prior to determining the average SAR. The proposed procedure is verified based on Finite-Difference Time-Domain (FDTD) calculation and measurement using electro-optic (EO) probes. For two reference dipoles, the differences in the 10 g SAR obtained based on the proposed procedure compared numerically and experimentally to that based on the original calculated three-dimensional SAR distribution are at most 4.8% and 3.6%, respectively, at 1950 MHz. At 3500 MHz, this difference is at most 5.2% in the numerical verification.
