摘要(中)	本論文提出應用於微小型行動路由器之天線設計，天線整體為全平面印刷，天線尺寸僅為45 × 15 × 0.4 mm3，搭接在系統主板的尺寸僅為90 × 60 × 0.4 mm3，且訊號源饋入置於天線板短邊，適合應用於小尺寸印刷電路板的無線裝置產品，例如行動式熱點分享器，無線攝影機(IP CAM)…等等。 首先，本論文天線設計之主結構，是將訊號饋入至單極化天線，去耦合四分之一波長共振的寄生元件，藉由彎折寄生元件的路徑，激發出0.698GHz和0.96GHz的雙低頻共振模態，以及2.17GHz和2.5GHz的高頻共振模態等共四個模態，經調適單極天線與寄生元件之間距，可優化低頻段的阻抗匹配，達到較寬的天線頻寬，其可涵蓋LTE Band 7/8/12/20/28頻段。為了增加天線之高頻頻寬，基於單極化天線的結構下，在其另一側延伸出一開路殘枝，激發共振在1.71GHz的模態；此外，也增加另一寄生元件當作匹配件，改善低頻與高頻的阻抗匹配。 本論文所提出之天線採用全平面印刷電路板製作，結構簡單，容易生產，且成本低，此天線操作在多頻帶，可涵蓋LTE Band 1/3/7/8/12/20/28/40 (0.698GHz~0.96GHz，1.71GHz~2.69GHz)，WLAN 2.4G頻段(2.4GHz~2.484GHz)，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)	Antenna design for miniature mobile hotspot routers is presented in the thesis. Realized on the FR4 printed circuit board, the antenna size is of 45×15×0.4 mm3 with system ground plane of 90×60×0.4 mm3. The proposed antenna is suitable for wireless device products of small size, such as mobile hotspot and wireless cameras (IP CAMs). The first antenna design is the main theme of the thesis. The monopole antenna, with a coupling parasitic path of the quarter-wavelength, can be excited at four resonant frequencies at 0.698 GHz、0.96 GHz、2.17 GHz and 2.5 GHz. Adjusting the distance between the monopole antenna and the parasitic path can optimize the impedance matching in the low band and improve the bandwidth which covers LTE Band 7/8/12/20/28 resonances. The second antenna is an open-circuit stub extended on the monopole antenna of main structure. The structure can be excited at 1.71GHz. Then, adding another parasitic element can improve impedance matching in both low band and high band. The proposed antenna has a simple structure, and can be easily constructed at low cost. It can cover LTE Band 1/3/7/8/12/20/28/40 (0.698GHz ~ 0.96GHz, 1.71GHz ~ 2.69GHz), WLAN 2.4G bands (2.4GHz ~ 2.484GHz). Detailed antenna design and experimental data are also presented and discussed.
