在本文中，我们提出的概念，选择性激励的正交模式的小终端电感和电容耦合元件。这些概念可以用于实现基于TCM（特征模式理论）的高效MIMO（多输入多输出）天线系统。这两个耦合的概念进行了讨论，他们的能力，分别激发特定的模式。获得的一个重要结果是，电感耦合器提供了优于电容耦合器的优点，在激励所需的模式纯粹，即使当他们不接近他们的模式谐振。
In this paper we present concepts for the selective excitation of orthogonal modes of small terminals by inductive and capacitive coupling elements. The concepts can be used to implement an efficient MIMO (Multiple Input Multiple Output) antenna system based on the TCM (Theory of Characteristic Modes). Both coupling concepts are discussed with respect to their ability to excite specific modes separately. An important result obtained is that inductive couplers offer advantages over capacitive couplers in exciting the desired modes purely even when they are not close to their modal resonance.
