摘要(英) |
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.
