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.
