| 摘 要： | 本文分析了阵列单元之间的互耦对智能天线阵列数字波束赋形（DBF）的影响。通过对天线子系统建立等效接收模型，对由理想半波振子组成的8单元圆阵（用于TD-SCDMA系统）进行矩量法（MOM）分析，得到表征单元之间互耦的广义阻抗矩阵，由此得到智能天线的互耦信息及其对天线性能（SINR）的影响。通过数值分析结果与试验的结果与对比可以看出互耦对副瓣电平和智能天线抑制干扰的能力有一定的影响。本文的分析对智能天线的研究具有一定意义。 |

| Abstract: | Digital Beam forming (DBF)of smart antenna with the effects of mutual coupling between array elements is presented, and an equivalent model of receiving system is setup and a circular array of eight ideal dipoles(for TD SCDMA System) is analyzed with MOM. The data about mutual coupling between elements are given and their effects on the performance of smart antenna are simulated. The comparison of analysis results and the measurement shows that the mutual coupling has a certain effect on the sidelobe and the ability of smart antenna to reject interference. The results are useful for the study of smart antenna. |
| Keywords: | Mutual coupling Digital Beam forming SINR Method of Moment(MOM) |
