This paper represents a comparative study on electromagnetic (EM) absorption in the human head between a printed monopole antenna and a planar inverted-F antenna (PIFA). The specific absorption rate (SAR) values and total absorbed power in the human head phantom are used to evaluate EM absorption for both antennae. Moreover, antenna performances in terms of return loss, radiation efficiency, and gain are also investigated in this study. The finite integration technique (FIT) based on CST Microwave studio and SAM head phantom are used in this study. The antenna performances are measured in an anechoic chamber and the SAR is tested using COMOSAR measurement system. The obtained results indicate that the printed monopole antenna lead to higher EM absorption in the human head as compared to PIFA for both GSM frequencies.
本文是对印刷单极天线和平面倒F天线（PIFA）在人体头部电磁（EM）吸收方面的比较研究。人体头部模型中的比吸收率（SAR）值和总吸收功率用于评估两种天线的电磁吸收情况。此外，本研究还考察了两种天线在回波损耗、辐射效率和增益方面的性能。本研究采用基于CST微波工作室的有限积分技术（FIT）和SAM人体头部模型。天线性能在消声室中测量，SAR使用COMOSAR测量系统进行测试。所得结果表明，在两种GSM频率下，与PIFA相比，印刷单极天线在人体头部导致更高的电磁吸收。
