在本文中,我们提出了一种基于小型终端上两个正交模式的选择性激励的双端口 MIMO(多输入多输出)天线。该概念应用了中医(特征模态理论)。底盘模式的激励是通过位于常用 PCB 上预定义位置的两组 ICEJn(电感耦合元件)实现的。馈电网络 (FNJn) 通过带状线技术实现的双短截线调谐和移相器实现 50Ω 的良好阻抗匹配。数值结果表明天线端口具有良好的去相关性和高质量的模式激励。
In this paper we present a two-port MIMO (Multiple Input Multiple Output) - antenna based on the selective excitation of two orthogonal modes on a small terminal. The concept applies the TCM (Theory of Characteristic Modes). The excitation of the chassis modes are realized by two sets of ICEJn (Inductive Coupling Elements) at predefined positions on a commonly used PCB. Feed Networks (FNJn) care for a good impedance match to 50Ω with double-stub tuning and phase shifters realized in stripline technology. Numerical results show a good de-correlation of the antenna ports and a high quality of mode excitation.
