为评估无线发射设备的电磁辐射比吸收率,本文构建了用于数值计算的标准中国人头模型(CHP).模型尺寸来源于中国发布的成年人头面部尺寸中的第50百分位的数据,模型的厚度及耳部的轮廓与特定标准头部模型(SAM)人头模型相同.构建了一个频率为1 761 MHz的PIFA天线手机模型对CHP模型和SAM模型进行SAR评估,并对评估结果进行了分析与讨论.
A Chinese head phantom (CHP) is constructed for evaluating the specific absorption rate (SAR) by the wireless transceivers. The dimensions according to the 50th percentile data of head-face dimensions of adults are released by China. The thickness of model and the configuration of the ear are the same as of specific anthropomorphic mannequin (SAM). A generated phone model with a 1 761 MHz PIFA antenna is used for the SAR evaluation of the CHP model and SAM model. The evaluation results are analyzed and discussed.
