LTE MIMO Antennas Analysis

即將進入無線通訊5G的時代,為了提升傳輸速率,手機LTE也開始建立MIMO的技術,新版的CTIA已經將MIMO的測試納入規範,尤其是要賣到日本電信龍頭Docomo的手機,已經要求要測試MIMO的性能。
MIMO的測試,CTIA有定義MIMO的天線治具,這邊挑了LTE Band-13的頻帶,去將模擬及實測量測的結果,一窺有關MIMO的測試及特性。

B-13 Reference Antennas from CTIA
下圖是整理在Band-13的MIMO的天線治具,採用雙天線達到MIMO效果,CTIA定義了Band-13有三大類MIMO天線。

好的MIMO天線要符合
1.低相關係數,要小於0.1
2.高輻射效率,要大於90%
3.低增益差值,也就是兩隻天線的輻射增益的差值,要小於0dB

一般的MIMO天線要符合
1.普通的相關係數,小於0.5
2.普通的輻射效率,大於50%即可
3.低增益差值,也就是兩隻天線的輻射增益的差值,要小於0dB

差的MIMO天線要符合
1.低的相關係數,大於0.9即可
2.低的輻射效率,小於50%即可
3.低增益差值,也就是兩隻天線的輻射增益的差值,要小於0dB
