為了瞭解不同操作機制之天線與其造成人體所吸收的電波能量之關聯性，本論文提出一系列操作於WLAN頻帶的平板電腦天線設計，分別是耦合饋入短路單極天線、耦合饋入迴圈天線、寬頻短路單極天線以及單極槽孔天線，並且對前述天線進行body SAR的模擬測試，分析在使用者以不同方式操作平板電腦時平板電腦天線的SAR值表現，比較不同操作機制之天線的SAR值表現。同時也分析在相同配置下改變天線與測試模型之間的距離時，天線SAR值的變化，找出天線與測試模型間所需要的最小距離以通過SAR規範。結果顯示耦合饋入迴圈天線具有較低的body SAR值，詳細的數據與分析在本論文中說明。最後並比較平面結構的天線與具有彎折的立體結構的天線兩者SAR值表現的差異。

In this thesis, a comparison of the body SAR value of five planar WLAN antennas including two coupled-fed shorted monopole antennas, a coupled-fed loop antenna, a monopole antenna, and a monopole slot antenna for tablet PC applications are presented. A required minimum distance between the antenna and the testing flat phantom to meet the 1-g body SAR requirement of 1.6 W/kg has been determined. Results show that the body SAR results of the coupled-fed loop antenna are lowest among the five tested antennas. Detailed results and discussion are presented in this thesis. Also, a comparison of the body SAR value of a planar antenna and an antenna with 3-D bent structure are presented.
