摘要

本研究提出了一个平板电脑在无线局域网波段的比吸收率（SAR）研究的数值模型。平板体模中的平板尺寸、工作频率、天线位置和目标1g峰值空间平均SAR（psSAR）值等设计标准是根据2013年至2017年在韩国分布的平板的SAR测试报告确定的。平板电脑平台中设计了一个内部天线，可在2450 MHz和5500 MHz的双频带中工作。数值结果表明，所提出的数值片剂模型的1g psSAR值在目标值的±10%以内。此外，所设计的平板模型的回波损耗大于10dB，而不考虑平面体模，而其在自由空间中的辐射效率高于90%。

Development of a Numerical Tablet Model in WLAN Band for SAR Study

This research proposes a numerical model for a tablet in the wireless local area network band for specific absorption rate (SAR) study. The design criteria, such as the tablet size, operating frequencies, antenna position, and target 1-g peak spatial-average SAR (psSAR) values in the flat phantom, are determined based on the SAR test reports of tablets distributed in South Korea from 2013 to 2017. An internal antenna is designed in a tablet platform to operate in dual bands of 2,450 MHz and 5,500 MHz. The numerical results illustrate that the 1-g psSAR values of the proposed numerical tablet model are within ±10% of the target values. Moreover, the return loss of the designed tablet model is larger than 10 dB, regardless of flat phantom, while its radiation efficiency is higher than 90% in free space.
