Abstract :
This paper derived the analytical expressions for both the mean received power of each antenna and the spatial correlation between antennas with mutual coupling. The effects of the coupling on mean power, spatial correlation and capacity of MIMO wireless channels were investigated. The conditions for the power balance and both the effect-free and decorrelation of the coupling are achieved, which shows the decorrelation is a tradeoff between mean DOAs and the pattern diversity due to mutual coupling.
