摘要

在这项工作中，我们提出了在其特定吸收率(sar)方面用于移动电话的各种天线的研究。设计并仿真了半波长偶极子天线(0.835 GHz)、矩形贴片天线(0.8 GHz)和平面倒F天线(0.8 GHz)等传统天线。为了降低它们的SAR值，在偶极子天线附近放置电磁带隙(EBG)结构。生成了s参数、辐射模式和SAR值等各种图来研究结果。设计了具有适当材料特性的六层人体头部模型，以便在SAR的详细研究中具有逼真的方法。所有模拟均在Ansys HFSS中完成。

Specific Absorption Rate Reduced (SAR) Mobile Phone Antenna Designs

In this work, we have presented a study of various antennas used in mobile phones in terms of their Specific Absorption Rates (SARs). Conventional antennas such as a half wavelength dipole antenna (0.835 GHz), rectangular patch antenna (0.8 GHz) and Planar Inverted F Antenna (PIFA) (0.8 GHz) are designed and simulated. In order to reduce their SAR values, Electromagnetic Band Gap (EBG) structure is placed near the dipole antenna. The various plots such as the S-parameter, radiation patterns and SAR values are generated to investigate results. The human head model with six layers having the appropriate material properties is designed to have a realistic approach in the detailed study on the SAR. All simulations are done in Ansys HFSS.
