摘要(中)

因應目前網路裝置無線化需求，本論文規劃一款LTE轉WIFI之MIMO天線系統整合設計，最主要節省了網路線的佈局及維護費用外，也讓使用者在家裡佈局放置AP可無線化更方便的使用。
本文利用廣域網路LTE系統轉區域網路WIFI系統架構，所設計出MIMO 2X2天線，為考慮裝置天線全球通用性，WIFI天線規格設計為2GHz及5GHz雙頻段，LTE天線規格則設計698 MHz ~ 2700 MHz全頻段，WIFI及LTE天線為縮小化都採用倒F天線設計結構，缺點為四支天線共用地，造成天線隔離度互相影響，經模擬驗證找出最佳解法。

關鍵字：LTE、WIFI、MIMO、AP、廣域網路、區域網路、倒F天線。

摘要(英)

For the purpose of current demand for wireless network equipment, this paper plan to build up an LTE MIMO antenna, which can integrate LTE with WIFI system. This not only to be more convenience and cost saving , but also allows users convenience can use internet at the home wirelessly.

In this paper, the usage of WAN LTE system to LAN WIFI switch system and the design of MIMO 2X2 antenna, are considering to install in the common usage of worldwide. This WIFI antenna design specifications at 2GHz and 5GHz dual-band, LTE antenna design specification is 698 MHz ~ 2700 MHz Full-band. Both WIFI and LTE antennas are designed to be PIFA type , the disadvantage for the four antennas are the isolation, due to they share the ground and close to each other. After simulation and verification, the best solution, had been found.

Keywords: LTE, WIFI, MIMO, AP, WAN, LAN, inverted F antenna.
