  • 本論文探討應用於超微型蜂巢式基地台(Femtocell)之中,設計LTE(Long Term Evolution)高增益陣列天線與WLAN MIMO( Wireless Local Area Network)( Multiple Input and Multiple Output )天線,並將二者整合於一體。第二章是運用電腦模擬於204(mm) x 204(mm) x 25(mm)之Femto AP(access point)塑膠盒內,設計2 x 2陣列天線,由盒內中心處製做接地面,輻射導體架設於接地面上方包含4個patch,訊號直接饋入於陣列天線中心位置,本設計介質採用空氣為介質,再將各個patch兩側邊緣中央處延伸寬為5mm的支架固定至接地面,並以實體製成量測與模擬結果分析比較,使其得良好輻射效率之目的。第三章則是承續配置好的陣列天線,與其共用接地,往Femtocell塑膠盒四側邊延伸,設計耦合式WLAN MIMO天線,並製作四組天線同時與Femtocell四側環境整合,藉此增加輻射涵蓋區域,實現與陣列天線整合之效果。第四章則是以相同天線位置,再設計倒F型WLAN MIMO天線,且同樣適用匹配至Femtocell四側,除了可增大其輻射空間區域之外,另一目標則是與陣列天線間之隔離度得以提升,且輻射效率更加優化。最後總結其倒F型WLAN MIMO天線與陣列天線之間隔離度相較於耦合式WLAN MIMO天線與陣列天線之間隔離度相差平均高於5dB以上,調整控制上也較耦合式容易些,且平均整體輻射率更為優異,更佳適合與該陣列天線整合應用。

    The thesis is to discover the way to design LTE high gain array antenna intetgrated with WLAN MIMO antenna for Femtocell Applications. In chapter two, we use HFSS to simulate 2 x 2 array antenna at 204 x 204 x 25 mm3 plastic Femto AP(access point). We make a ground inside the box and let the feeding point at center antenna. The air is the medium for array antenna to radiate. Every patch extends to ground by 5 mm width. Afterward we can analyze the result from computer simulation test and actual object test and get a nice radiation efficiency.
    In chapter three, we use the ground of array antenna as the some ground of Coupling structure WLAN MIMO antenna. And then make the Coupling structure WLAN MIMO antenna integrated with antenna array. There will be four Coupling structure WLAN MIMO antennas at every middle side of Femtocell to add radiation area. In chapter four, we remove all Coupling structure WLAN MIMO antennas, and design a kind of PIFA WLAN MIMO antenna which also has the ground of antenna array. Let four PIFA WLAN MIMO antennas set at the places where Coupling structure WLAN MIMO antennas were set similarly.
    The purpose is not only promote the radiation area but also the isolation(Between PIFA WLAN MIMO antennas and array antenna). Finally, PIFA WLAN MIMO antennas have much better isolation(more than 5 dB) and average radiation efficiency than Coupling structure WLAN MIMO antennas for the Femtocell. The PIFA WLAN MIMO antenna is also easily to controlled frequency band. Thus the PIFA WLAN MIMO antenna is fit with antenna array for LTE Femtocell application.
