Abstract :
Spherical vector waves are used to analyze multiple-input multiple-output (MIMO) antennas. An expansion of the far-field pattern in spherical vector waves gives the correlation matrix and correlation loss of the MIMO antenna in uniform multipath channels. Numerical examples of a MIMO tetrahedron and a MIMO cube are presented
