本篇論文主要是應用於筆記型電腦的觸控板模組上。第一章說明研究背景與目的；第二章主要介紹什麼是NFC；第三章主要是設計NFC讀取器天線，研究不同走線方式於各種觸控板底下，卡片讀取距離會有什麼樣的變化；第四章主要是設計NFC 標籤天線，研究何種類型的線圈型式，可在天線面積縮小後，還能讓讀取器感應到一定的範圍；第五章是用讀取器原有的架構中，添加標籤天線，組合成新的NFC 雙模天線，以實現節省空間為目標，匹配電路的部分參考恩智浦的設計，來達成讀取器與標籤的功能切換，然後天線部分將根據前面的實驗結果，進行組合測試並且發現兩個天線距離太近，會產生互相干擾或偶合的情況，因此調整兩者天線間距或者線圈，以改善某些卡片無法讀取的問題；第六章為本論文結論，對第三、四、五章所提走線方式作出一個總結。

This article is mainly applied to the touchpad module of laptop. The first chapter describes the general background information and the research purpose; the second chapter introduces what NFC is; the third chapter mainly designs the antenna of the NFC card reader, and studies the changes in the reading distance of various touchpads under different wiring layouts; the fourth chapter is mainly to design the NFC tag antenna, to study which type of coil, when the antenna area is reduced, NFC reader can still induction a certain range; the fifth chapter is to use the original structure of the reader, put the tag antenna in the middle, and combine it into a new NFC dual-mode antenna to save space. The matching circuit part refers to the design of NXP to realize the function switching of the reader and tag, and then according to the experimental results of the previous chapters, the reader antenna and the tag antenna are combined and tested. It is found that the distance between the two is too close, which will cause mutual interference or coupling. Therefore, adjusting the antenna spacing between the two can improve the problem that some cards cannot perceive ; the sixth chapter is the conclusion of this article, which summarizes the wiring methods proposed in the third, fourth and fifth chapters.
