摘要

人们普遍认为，全面了解人类和个人通信天线之间的电磁相互作用对于现代手持天线设计至关重要。将时域有限差分法与特征函数展开法的结果进行了比较。此外，还比较了带解剖头的半波天线与球形头的近场和远场图像。我们表明，用球形头获得的结果可以为各种天线设计目的提供有用的估计。最后，给出了六层球头的工程设计数据。我们主要关注900兆赫的结果。

EM interactions between handheld antennas and human: anatomical head vs. multi-layered spherical head

It has been widely acknowledged that comprehensive understanding of EM interactions between human and personal communications antennas is essential for modern handheld antenna design. Results using the FDTD method for the spherical head are compared with those using the eigenfunction expansion method. Also, the near- and far-field patterns of a half-wave antenna with the anatomical head are compared with those of the spherical head. We show that the results obtained with the spherical head can provide useful estimates for various antenna design purposes. Finally, we present engineering design data obtained with a six-layered spherical head. We mainly focus on 900 MHz results.
