本文提出了一种适用于密集阵元天线系统的可调谐解耦方法,该方法能够提高各调谐状态的解耦带宽。去耦方法利用寄生散射体和可调谐电路元件,其设计方法进行了系统的研究。去耦方法进行评估,通过执行一个模拟,其中在调谐状态下的三元件天线系统的去耦带宽进行检查。在这种情况下,仅优化电路元件。作为这个过程的另一个例子,频率可重构的去耦带宽为两个元件的天线系统示出通过优化的寄生散射体和电路元件在无损和现实的情况下,以增加。本研究的结论是提出了一个现实的评估在不同的调谐状态下的两个元件天线的去耦。
This article presents a tunable decoupling method for closely spaced multielement antenna systems, which is able to enhance the decoupling bandwidth of each tuning state. The decoupling method utilizes parasitic scatterers and tunable circuit components, and its design approach is systematically studied. The decoupling method is evaluated by performing a simulation in which the decoupling bandwidth in a tuned state for a three-element antenna system is examined. In that case, only the circuit components are optimized. As another example of this procedure, the frequency reconfigurable decoupling bandwidth for a two-element antenna system is shown to increase by optimizing the parasitic scatterer and the circuit components in the lossless and realistic cases. This study is concluded by presenting a realistic evaluation for the decoupling of a two-element antenna in different tuned states.
