中文摘要 |
本論文主要根據現今室內無線通訊系統,提出應用於多輸入多輸出系統之室內無線通訊天線,首先針對發射端部分提出新型多輸入多輸出系統天線,可大幅縮小多輸入多輸出系統橋接點天線使用時所佔之空間。再來針對接收端部分,提出適用於兩種不同裝置之多輸入多輸出系統天線,分別為個人數位助理手機與筆記型電腦,此兩裝置雖為不同之應用,但於天線設計時我們仍採用倒F形平面天線設計,其設計準則大致相同,因此在設計多輸入多輸出天線時,設計重點將著重S參數之探討與分析,詳細的天線設計及實驗數據將在本論文說明及討論。 |
Abstract |
In this thesis, the studies mainly focus on recent trends in novel MIMO antennas for indoor wireless communication system. Firstly, we propose a novel MIMO antenna for access-point application. This proposed antenna can reduce the lateral length of the conventional access-point antenna for MIMO application. Then, we present MIMO antenna designs for mobile devices such as PDA phones and laptop computers. Although these two devices are of different configurations, the PIFAs are applicable in these two devices, and their design rules are basically the same. Thus, for this study, the design consideration of the MIMO antenna will focus on S-parameter analysis. Detailed antenna designs and experimental results are presented and discussed in this thesis. |
