行動裝置是目前消費性產品市場中的主流應用。它變得更薄，更輕，但整合了更多的功能，如全球衛星定位(GPS)導航, 數位相機以及近場通訊（NFC）等應用。因此，需要在有限的設計區域內整合更多的功能，和要求更長的電池壽命，以支持行動裝置的日常工作。
大多數移動設備使用的電池，是直接從電源供應器充電。在我們周遭行動裝置，每個都需搭配電源供應器。如手機和iPad類似的產品，相當的不方便，並產生不必要的電器廢物。對於這個問題的解決方案之一是採用無線電力傳輸技術， 並遵守無線電源傳送WPT標準，來共享無線電源充電器的設備。讓電源傳送更方便以及節省成本。但是一個顯見的問題是整合WPT線圈於有限的空間內。
近場通訊 (NFC) 技術源自於RFID技術，隨著行動裝置的普及，近場通訊技術應用於個人資訊交換，像是小額付費機制、會員卡、大眾交通工具支付卡, 此應用大大的增加生活上的方便性。
本論文討論了無線電力傳輸和近場通信電路整合，將無線傳能與近場通訊的天線整合在同一個位置，利用磁性材料與金屬天線參考平面的設計，降低電磁渦流效應，提升天線的性能表現，並借由控制電路來開啟與關閉電線電路，降低電路間的干擾，並佐以訊號模擬和量測數據證明此概念。

Mobile devices are the major applications in the main stream consumer products. It becomes thinner and lighter but integrates more functionality, such as GPS navigation, Digital Camera and Near Field Communication (NFC) applications. Thus challenges of limited area integration and required longer battery life to support our daily works.
Most of mobile devices work with battery and directly charges from power adapter. Look around us, each mobile or handheld devices are accompany with a power adapter. Like cell phone and iPAD like products, it’s not convenient and generates electrical wastes. The one of solutions for this problem is employed Wireless Power Transfer technique and adopts WPT standards for sharing power adapter device. Make power transfer convenient and save cost. A coming problem is to integrate WPT coil into area limited mobile device.
Near Field Communication (NFC) is a new wireless communications technology with security support. NFC offers users much kind of services like payment, loyalty, transport, travel, culture, and infotainment. Mobile phones can be used as virtual vouchers, transport tickets, or even supermarket loyalty cards. a NFC device can act as a NFC tag emulator or a tag reader. Operating at 13.56 MHz and transferring data.
Regarding loop antenna design principle is similar and cellular phones design mechanical spacing limitation, Wireless charging and NFC combo solutions realized the limit of design size. NFC (Near Field Communication) and wireless charging integrates in one module and coil/sheet provides low power consumption with high efficiency in mobile electronic device.
This thesis discussed the integration of Wireless Power Transfer and Near Field Communication circuits. The paper represents simulation and measurement data for proving the concept.
