Abstract The effect of mutual coupling among array elements on the performance of MUSIC algorithm is investigated. The presence of mutual coupling distorts array response vector and the eigenstructure of the covariance matrix. The Method of Moment (MoM) is used to evaluate the mutual coupling among the dipoles. The admittance matrix is then used to eliminate the effects of mutual coupling. Finally, the results of computer simulation are given.
