在本論文提出無線充電之磁共振系統與天線設計，應用頻段為6.78 MHz之，符合A4WP聯盟的Rezence規範。利用電磁模擬軟體(HFSS 15)進行分析以及優化，最後，以實際製作共振線圈，量測S參數、傳輸係數，驗證共振天線之傳輸效率。
內文提出兩種磁共振線圈的設計方式，分別為「單極式」與「雙極式」磁共振天線，天線均採用平面式設計，使線圈不易受到擠壓變形，尺寸為150 × 150 × 1 mm3 之FR4板，並比較兩種線圈之差異，其中雙極式線圈在各方面性能皆優於另一個。
在最後將兩種天線結合系統，並比較量測不同距離的傳輸表現進行探討與分析，能在未來進行改良與優化，實現大尺寸充電板之應用。

In this paper, the magnetic resonance system and antenna design for wireless charging are proposed, and the operation frequency is fixed to 6.78 MHz, which is in line with the Rezence specification of the A4WP Alliance. The electromagnetic simulation software (HFSS 15) is used for analysis and optimization, the Resonance coils are measured (S-parameters, transmission coefficient) to compare with the simulation results.
The magnetic resonance coils are designed in two configurations: "unipolar" and "bipolar". All antennas are etched on the size of 150 × 150 × 1 mm3 FR4 substrates, make coil not easily deformed by extrusion and compare the differences between the two coils.
In the end, the two antennas are combined into the system, and the transmission performance of different distances is compared and analyzed. It can be improved and optimized in the future to realize the application of large-size charging board.
