緒論
無線傳輸容量對於行動通訊十分重要，而多天線技術，一般稱之為 MIMO, 經由分集技術、空間多工、波束成形，可以幫助改善無線通訊的傳輸效能。

結論
本文中基於 S 參數使用動差法 (MoM) 計算信號通道
容量，結果顯示，延長天線長度可使多模組式傳輸(MMT) 增加信號通道容量，當長度超過 1.1λ 時，使用單一傳輸模式 (SMT), 可讓通道容量增加並超過理想匹配。最後，本文中的各種結果證明，最佳的天線激勵
將提供比傳統中心饋電偶極天線更棒的信號通道容量。

心得
在製作 PPT與搜尋資料的過程中，遇到了相當大的困難在一開始，許多專有名詞是由英文組成，在資料查詢的過程中遇到相當大的困難，問了通訊相關系所的同學也無法得到解答，雖然做完整份報告，相信內容依舊錯誤百出，不過在整個過程中，可以增加自我的資料蒐尋及英文閱讀能力，仍然是一次相當不錯的經驗。
