手机天线辐射与人头吸收率的仿真分析

内容简介：利用HFSS软件仿真分析了PIFA手机天线的电磁辐射特性。为改善天线的性能，在原结构基础上添加了金属屏蔽板，研究了加入屏蔽板后天线性能的变化情况。通过HFSS仿真人体头部模型内的电场和整体的SAR分布的方向图，仿真结果表明，加入屏蔽体后人体头部的辐射电场和SAR分布明显减弱。

Abstract：The EM properties of planar inverted F-shaped antenna (PIFA) are analyzed with the help of the software High frequency structure simulator (HFSS) in this paper, and then, in order to improve the perform- ance of the antenna, a metal shielding plate is introduced into the model structure. We also propose the changes of the new style antenna. Simulation of the electric field in the head of human beings and the SAR radiation pattern shows that the radiation and the distribution of SAR are reduced significantly.
