Wideband Analysis of Mutual Coupling Compensation Methods
Figure 9
Array gain using the receiving mutual impedance (RMI) method as a function of the electrical separation () between the elements of the nine-dipole planar array for a signal arriving from . Maximum gain is achieved for . The performance degrades as frequency increases and becomes dependent on the excitation DOA used in the computation of the coupling matrix estimate. Nevertheless, it is superior to that of the uncompensated case for all the plotted frequencies.
