  2. 比較案例 比較方式

  3. 比較案例 比較方式

  4. 比較結果 雖兩支天線都是使用MIMO作法,但是達到的頻帶與使用 規範並不一樣,兩方各有特色,使用PIFA達到WLAN2.4 GHZ 但是只有做到單一頻帶,隔離機制使用T型與中性 線讓隔離度達到要求。而另一支天線使用單一槽孔達到 隔離效果,經由作者的電流圖來看,此槽孔具有吸引電 流之功用,使兩支天線的互相作用降低,但是製作空間 比前者增大許多,可能是兩個天線主體離得比較遠故有 一些隔離的作用存在。

  5. 心得 兩支天線都有各自特色,但PIFA的天線可能礙於空間受限 只完成單一頻帶感到可惜,而槽孔天線可能是因為空間較 足有做到LTE雙頻,應用範圍較廣。單一個SLOT就可以吸 引電流讓天線降低相互干擾,這點讓我感到很實用,在 MIMO天線中設計一個隔離機制並有效抑制天線間的相互 干擾是不簡單的事情,但也是技術所在。
