The impact of mutual coupling on the performance of multiple-input multiple-output(MIMO) systems with compact antenna arrays is analyzed.This article aims to use the S-parameter modeling approach to examine the impact of mutual coupling on three system-related performance measures:antenna correlation,efficiency and bandwidth.It is shown that implementing a good matching network can drastically improve the system performance in the presence of strong mutual coupling.Experiment results indicate the superiority of cross-shaped antenna to dipole antenna.
