| 摘 要： | 通过建构接近于真实情形的三维旋转人头模型，在天线处于垂直和三维旋转两种方式下，应用时域有限差分法(FDTD)模拟计算了人体接受单极天线手机的电磁辐射剂量．研究了人体对手机天线方向图及其发射效率等辐射特性的影响，并将倾斜操作方式与垂直使用方式进行了对比．计算结果表明，使用手机时选择倾斜操作方式，在不显著影响天线通信质量情况下，一定程度上可降低手机对人体的电磁辐射强度．

| Abstract: | By establishing the three-dimension rotated human head model proximate to practical operations, the electromagnetic radiation dosage emitted from vertical and rotational handset antennas into a human body was simulated through the finite-differencetime-domain (FDTD) method. The effects of a human body on antenna's radiation characteristics including the pattern and the radiation efficiency, were also investigated. Moreover, the difference between the vertical and the tilted operations was analyzed. Calculated results indicate that the radiation dosage radiated to a human body in tilted operation is less than that in vertical operation in certain degree, without remarkable influence on the communication quality. |
