为了提高亚太赫兹和太赫兹通信系统的容量和传输距离，人们提出了多输入多输出(MIMO)系统。虽然已经做了很多工作来铺平使用全向或半全向天线单元的阵列和子阵阵列的道路，但很少有人探索定向天线单元在(亚)THzMIMO系统中的好处。本文简要介绍了亚太赫兹和太赫兹多天线系统的研究现状，并在前人工作的基础上提出了在亚太赫兹和太赫兹多天线系统中使用更多定向天线单元的建议。亚太赫兹分集方案的第一个实验实施也被用来验证发现。数值和实验分析都表明，在亚太赫兹和太赫兹MIMO中，定向天线单元由于其聚焦功率和辐射方向图的形状，可以提高可实现的数据速率。
Multiple-Input Multiple-Output (MIMO) systems have been proposed to increase the capacity and transmission distance of sub-THz and THz communication systems. Although much work has been done to pave the way for arrays and arrays of subarrays using omnidirectional or semi-omnidirectional antenna elements, few works explore the benefits of directional antenna elements in (sub-)THz MIMO systems. This work presents a brief survey of what has been done for sub-THz and THz multiple antenna systems and builds on the previous work to suggest using more directional antenna elements in sub-THz and THz MIMO systems. The first experimental implementation of a sub-THz diversity scheme is also used to verify the findings. Both the numerical and experimental analyses demonstrate that directional antenna elements in sub-THz and THz MIMO can increase the achievable data rates due to their focusing power and the shape of their radiation pattern.
