    Abstract: 本論文以行動支付所用的NFC標籤天線進行研究,當NFC標籤天線置入於手機背蓋與電池的中間空隙,如何讓NFC標籤天線達到最大電磁感應距離為本文研究重點。
    本文依據天線和電磁學原理,用HFSS(High Frequency Structure Simulator)進行軟體模擬。選用軟性印刷電路板(Flexible Print Circuit, FPC)製作標籤天線,最後使用Agilent E5061A頻譜分析儀進行近場標籤天線的參數量測,過程紀錄了標籤天線外型、匹配電容值、吸波材(Absorber)對電磁感應距離的影響。本論文研究的數據及經驗可供NFC無線充電系統設計使用。
    ;This thesis designed NFC tag antennas embedded in the middle of mobile phone back cover and battery, and we used NFC tag to reach the maximum distance of electromagnetic induction.
    Based on antenna and electromagnetic theory, we used high frequency structure simulator (HFSS) software to do emulations. We chose flexible printed circuit board (FPCB) to make the NFC tag antenna and measured the bandwidth by using Agilent E5061A spectrum analyzer.
    At the same time, we had also recorded the influence of the shape of NFC tag antenna, match capacitance value, and absorbing material relationship on the distance of electromagnetic induction.
    Based on the research results, we can apply to the development and the reference of design of NFC wireless charging hardware in the future.
