摘要

本文介绍了利用偶极子天线和微带贴片天线研究人体头部电磁吸收的方法。这两种天线都是为2.2 GHz的无线设备设计的。使用两个参数来研究电磁吸收-人体头部组织的峰值比吸收率(SAR)和无线设备用户的总保留功率。将两根天线设置在固定距离，分析MPA天线和偶极子天线对人体电磁吸收的影响。采用传输线法求出MPA参数。通过CST微波工作室对两种天线进行了设计和仿真。结果表明，在人的头部，MPA比偶极子天线提供更低的峰值SAR值。因此，偶极子天线的总吸收功率大于MPA。因此，在减少电磁吸收方面，MPA是无线设备的更好选择。

Comparison of Electromagnetic Absorption in Human Head for Dipole and Microstrip Patch Antenna

The paper presents, the investigation of electromagnetic (EM) absorption in the human head using dipole and microstrip patch antenna (MPA). Both antennas are designed for working in wireless devices at 2.2 GHz. Two parameters are used for the investigation of electromagnetic absorption-peak specific absorption rate (SAR) in the human head tissue and aggregate retained power from the wireless device user. Both antennas are set at a fixed distance to analyze the effects on human head for electromagnetic absorption for MPA and Dipole antenna. Transmission line method was adopted to find out the parameters of MPA. Both antennas are designed and simulated via CST microwave studio. The outcomes demonstrate that, in human head MPA provides a lower peak SAR value than Dipole antenna. So, total absorbed power of Dipole antenna is higher than MPA. Therefore, MPA is a better option for wireless devices regarding EM absorption reduction.
