  如何避免相互耦合是設計多輸入多輸出天線系統的重要問題,因為它會產生破壞性干涉,影響到天線的效率,在本論文中,提出利用在天線之間加入具有帶拒濾波器特性的開口諧振環,改變接地面結構,並探討對隔離度的影響。研究結果發現開口諧振環的尺寸控制抑制頻段的中心頻率,不同開口方向和位置對天線系統的隔離度也有不同的影響,量測結果證明開口諧振環可以減少相互耦合量,並提高天線系統的隔離度,同時也能有效提升天線的增益與輻射效率。

  Mutual coupling has been a critical issue on designing MIMO antenna systems. Mutual coupling produces destructive interference and which reduces the efficiency of the antenna. In this study, split-ring resonator having a band-stop filter characteristics, is placed to between the antenna and the effect of isolation is investigated. The size of the split-ring resonator controls the center frequency of suppression, opening directions and position have effects on the isolation of the antenna system. The measured results show that split-ring resonator not only reduces the mutual coupling of the antenna system, but also enhance gain and radiation efficiency of the antenna.
