摘　　要：文章简要概括了MIMO系统及其信道容量,并基于矩量法重点分析了MIMO系统中天线阵元间的互耦作用对每个天线阵元辐射方向图的影响。结果表明互耦能使每个天线阵元的方向图发生畸变,所以在应用射线追踪法构建MIMO系统的信道矩阵时必须考虑互耦的影响以提高计算精度。MIMO communication system, including its capacity, is described in brief. The analysis based on the method on moments, focuses on mutual coupling between the array elements and its effects on the radiation patterns. It is shown that mutual coupling may lead to a distortion of the radiation pattern for each element as compared with the isolated one so that when applying ray tracing techniques to construct MIMO channel matrix, mutual coupling effects must be taken into consideration for improving the accuracy.
