摘要/Abstract

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．

关键词: 单极天线, 三维旋转, 辐射剂量, 辐射特性

Abstract: By establishing the three-dimension rotated human head model proximate to practical operationsthe 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 efficiencywere also investigated．Moreoverthe 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 degreewithout remarkable influence on the communication quality．

Key words: monopole antenna, three-dimension rotation, radiation dosage, radiation characteristic
