Antenna arrays are very important in wireless communication networks, as they can sustain radiation direction change, with high capacity and high gain requirement. Mutual Coupling (MC) between antenna arrays has effects on some parameters, impedance, reflection coefficients, radar cross-section, and array performance. Most significantly, the MC has greatly influenced the efficiency of the antenna array. This phenomenon reduces array signal processing efficiency. To address this constraint, different approaches have been proposed in this article. The usefulness of multiple approaches lies to a major degree in implementations in which the arrays have been applied. This article is a comprehensive study for investigating MC influences on several parameters, including impedance and radiation pattern. In addition, some developed decoupling methods are outlined, receiving the Mutual Impedance Method and S-Parameter Process, including the open-circuit voltage mechanism. This can aid in contrasting the different strategies in order to allocate enough knowledge to help future research.
