本論文中提出一種具有分佈式LC匹配電路之八頻內藏式手機天線設計，除了可滿足LTE/WWAN的八頻操作頻帶，也非常適合應用於薄形行動通訊裝置之中。本發明天線利用內藏分佈式匹配電路來改善頻寬，同時具有良好的輻射特性，且體積僅只有60 × 10 × 3 mm^3。本論文中同時探討人體效應對天線輻射特性的影響，且針對使用者手部及頭部對於手機天線位置不同所造成的不同影響進行分析。此外，本論文也對於本天線設計的SAR及HAC值進行模擬測試，並對出音孔位置不同導致近場電磁場的場量有所差異作探討與分析。

In this thesis, an internal mobile phone antenna with a distributed matching circuit for eight-band LTE/WWAN operation is presented. By selecting proper dimensions of the distributed matching circuit, the bandwidth of the proposed antenna can be greatly enhanced. Good radiation characteristics are also obtained, and the proposed antenna occupies only 60 × 10 × 3 mm^3 and is very suitable for slim mobile phone applications. Effects of the human body including user’s head and hand are also studied, and the SAR and HAC issues are simulated and analyzed in this thesis.
