隨著科技的進步，無線網路的普及，天線設計也不得不跟緊時代的腳步；本論文的研究主要為筆記型電腦與平板電腦之無線廣域網路天線的設計，改善以往USB dongle的外露天線，將天線內藏於行動通訊裝置內，插入手機用之SIM卡即可隨時隨地無線上網，論文中提出三款結構不同之天線設計，以簡易的設計結構、短小的天線尺寸，符合GSM 850/900 (824 ~ 960 MHz)、DCS/PCS/UMTS (1710 ~ 2170 MHz) 之操作頻段，其中一項天線更可涵蓋至WLAN (2400 ~ 2484 MHz) 及 WiMAX (2300 ~ 2400 MHz & 2500 ~ 2690 MHz)，具有單一天線，多頻操作之優勢，天線增益與輻射效率皆有良好的表現，且適合內藏於筆記型電腦中，取代外接式無線網卡天線。

As technology advances and wireless network popularity, antenna design have to bear with the pace of the times. This study mainly designs the wireless wide area network (WWAN) antenna for Laptop Computer and tablet PCs, improving the external antenna design in USB dongle. The WWAN antenna can built in the mobile communications device with SIM card, then it could be surf the internet at anytime. In this thesis, three different structures of antenna design were proposed, which were a compact and simple structure. The proposed antenna operate at GSM 850/900, DCS/PCS/UMTS, WLAN and WiMAX bands, which have good antenna gain and radiation efficiency. All the proposed antenna are suitable for embedding in the Laptop computer.
