    Abstract: 本論文研究之目的是在於探討何種天線組合最適用於802.11n無線區域網路接取器,並且依此分析進行天線設計。從一開始對無線區域網路的介紹,接著進行分析本系統的天線需求為何,進而由天線的各種參數特性中,進行設計、改良,再經由電磁模擬軟體的驗證後,進入實做驗證與測試,最後得到一完整天線組合,其各方面的特性皆符合本論文所規劃與設定,並且與習知天線相比,有著大幅的進步,其中天線效率提升了35%以上,水平面平均增益值更大幅提升超過了4dB,達到水平面平均增益值高於0dBi,同時此天線組合還在空間、極化與場形達到了良好的分集,成為適用於802.11n無線區域網路接取器天線組合成效卓著之改良。 Purpose that thesis study this is it discuss which kind of antenna is it apply to 802.11n WLAN AP most to make up to lie in, and design the antenna in analysis according to this. Introduction of WLAN, is it analyses why it will be antenna demand of system this to go on then from the beginning, and then design, improve from various kinds of parameter characteristics of the antenna, and then after the verification of the electromagnetic simulation software, entering and proving and testing in fact, get an intact antenna of associations finally, its characteristics of various fields all accord with this thesis to plan and set up, and compared with known antenna, there is progress by a wide margin, among them the efficiency of the antenna has been improved by more than 35%, the average gain of azimuth plane has improved and exceeded 4dB by a wide margin even more, the average gain of azimuth plane is higher than 0dBi, at the same time this antenna was made up great diversity also on the space, polarization and radiation patterns, really become suitable for 802.11n WLAN AP.
