本文研究了一种新型圆形智能天线阵在3G通信系统所在频段的互耦补偿.采用矩量法分析了阵列的互耦和导引向量、阵列流形的补偿,在此基础上实现了下行链路波束形成和上行链路DOA算法的补偿,同时通过实验验证了互耦补偿的有效性.

This paper investigates the benefit of mutual coupling compensation in a novel smart antenna circular array at 3G-communication system frequency.Mutual coupling of antenna arrays and the compensation of steering vector and array manifold are analysed via method of moment (MoM).Based on it,the paper implements the compensation of downlink beamforming and uplink DOA algorithm.Finally,experiments in antenna array prove the efficiency of mutual coupling compensation.
