Summary:
Maximum power feed efficiency of MIMO antenna with intensive mutual coupling on handset is achieved not by match or conjugate match source impedance configuration, but by the source impedance that introduces small reflection between the sources and the antenna network to reduce the power transmitted from the one source and absorbed by other sources. A novel model for calculating the absorbed power by the sources is developed for multiple antenna network to overcome the defect of Thevenin and Norton equivalent circuits model. The algorithm to calculate the source impedance for maximum feed efficiency is proposed.
