摘要:	本研究論文中所提出的多頻天線設計，除了可滿足無線廣域網路及長期演進的八頻操作頻段，也適合內藏於筆記型電腦中。首先，將單極天線做一改良，產生0.94GHz、 1.67GHz 、2.035GHz 及2.41GHz 等四個共振頻率點，且它可涵蓋 DCS1800/PCS1900/UMTS/LTE2300/LTE2500 的五個操作頻段。接著，於單極天線加上四分之一波長共振的寄生路徑，能使低頻產生雙共振及改善阻抗頻寬，產生寬頻並涵蓋 LTE700/GSM850/900 的三個操作頻段。最後，提出一種結構簡單、製作容易、成本低廉且可應用在無線廣域網路中的金屬板與印刷電路板結合的天線。它能涵蓋八個頻帶，包含了LTE700/2300/2500 的三個LTE 頻段及GSM850/900/DCS1800/PCS1900/UMTS 的五個WWAN 頻段，且天線體積僅為65 × 14 × 2.3 mm3。詳細的天線設計及實驗數據將在本論文中說明及討論。 In this thesis, Internal WWAN (Wireless Wide Area Network) and LTE (Long Term Evolution) antennas having eight-band operation capability and suitable to be embedded in the laptop computers are proposed. At first, a modified monopole antenna is uesd to produce four resonance frequencies 0.94GHz、1.67GHz、2.035GHz and 2.41GHz. The penta-band DCS1800/PCS1900/UMTS/LTE2300/LTE2500 operation is covered in this design. Then, with the monopole antenna and a quarter-wavelength parasitic path, we can have dual-resonance in the low band and improve impedance bandwidth, resulting a broadband coverage for the tri-band LTE700/GSM850/900 operation. Finally, a novel metal-plate and printed circuit board (PCB) combo of WWAN antenna, having a simple structure and being easy to construct with low cost, is presented. It can cover eight bands, including three LTE bands of LTE/700/2300/2500 and five WWAN bands of GSM850/900/DCS1800/PCS1900/UMTS operation, and occupy a compact volume of 65 × 14 × 2.3 mm3. Detailed antenna designs and experimental results are presented and discussed.
