Kertas kerja ini mencadangkan dan mengesahkan prosedur pengukuran kadar penyerapan (SAR) khusus untuk pemancar berbilang antena yang memerlukan pengukuran taburan medan elektrik dua dimensi untuk bilangan antena dan pengiraan untuk mendapatkan taburan SAR tiga dimensi untuk pekali pemberat sewenang-wenangnya. daripada antena sebelum menentukan purata SAR. Prosedur yang dicadangkan disahkan berdasarkan pengiraan dan pengukuran Finite-Difference Time-Domain (FDTD) menggunakan probe elektro-optik (EO). Untuk dua dipol rujukan, perbezaan dalam SAR 10 g yang diperoleh berdasarkan prosedur yang dicadangkan berbanding secara berangka dan eksperimen dengan yang berdasarkan taburan SAR tiga dimensi yang dikira asal adalah masing-masing paling banyak 4.8% dan 3.6%, pada 1950 MHz. Pada 3500 MHz, perbezaan ini adalah paling banyak 5.2% dalam pengesahan berangka.

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.
