摘要

本文对手机用户头部与MIMO天线阵列之间的相互作用进行了数值研究。天线阵由两根相同的天线组成，覆盖频率范围为698-990 MHz和1710-5530 MHz，在自由空间具有良好的辐射效率。考虑了交互作用的两个方面:1)用户头部对天线运行的影响，2)人体头部组织对天线电磁辐射的暴露。第一个方面与天线在接近用户时性能的下降有关，这是通过天线辐射效率的降低来评估的。二是天线工作对人体的影响，利用比吸收比(SAR)研究用户头部的暴露。

Study of the interaction user head-ultrawideband MIMO antenna array for mobile terminals

This paper presents a numerical study of the interaction between the user head and MIMO antenna array for mobile phones. The antenna array is composed of two identical antennas and covers the frequency ranges 698-990 MHz and 1710-5530 MHz with a good radiation efficiency in free space. The two aspects of the interaction are considered: 1) the influence of the user head on the antenna operation, and 2) the exposure of the human head tissue to antenna electromagnetic radiation. The first aspect is related to the degradation of the antenna performance in a proximity to the user which is evaluated by the reduction of the antenna radiation efficiency. The second aspect refers to the antenna operation effect on the human and the exposure of the user head is studied by Specific Absorption Ratio (SAR).
