Abstract：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.
