摘要(中) 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。
摘要(英) 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.
