用于商业的便携式无线电终端通常被保持在人体附近，需要注意腹部中的特定吸收率（SAR）。因此，为了评估当佩戴用于商业的便携式无线电终端时人体中的SAR，对在150MHz下模拟用于商业的便携式无线电终端的具有金属外壳的正常模式螺旋天线（NHA）进行建模。此外，将在组织等效体模附近使用带金属外壳的NHA的SAR分布计算结果与测量结果进行了比较。结果表明，计算结果与实测结果的SAR分布吻合较好。
The portable radio terminal for business is usually hold in the vicinity of a human body, it is needed an attention for the specific absorption rate (SAR) in an abdomen. Therefore, in order to evaluate the SAR in the human body when wearing the portable radio terminals for business, the normal-mode helical antenna (NHA) with metallic case, which simulates the portable radio terminals for business at 150MHz, was modeled. In addition, the calculations of SAR distributions employing an NHA with metallic case in the vicinity of the tissue-equivalent phantom were compared with the measurements. As a result, the SAR distributions of calculated result agree well with those of measured result.
