多天線系統(tǒng)的互耦抑制(英文)
發(fā)布時間:2023-01-31 09:12
多頻帶多天線系統(tǒng)已成為移動通信系統(tǒng)發(fā)展的重要趨勢。但是,由于空間較小,天線單元之間往往會發(fā)生較強互耦,從而損壞陣列天線的性能。因此,在多輸入多輸出(MIMO)天線系統(tǒng)中,人們一直追求在天線陣列小型化的基礎上,實現(xiàn)較高的隔離度。本文深入研究天線單元間的去耦方法,分析互耦原因及耦合減少的優(yōu)勢。然后,比較分析近期提出的解耦方法。最后,提出由雙層短截線組成的超表面結(jié)構(gòu),以改善沿H面和E面排列的天線的端口隔離。結(jié)果表明,所提超表面對緊密放置的天線陣列具有良好去耦效果。
