Abstract(s)

Nowadays, a common concern in 5G communications is the large amount of antennas per array, this is important in mMIMO solutions. This imply a reduction of space between elements, and thus a significant increase in coupling.This paper presents a new solution to reduce mutual coupling in an antenna array. A parametric study was made to determine the influence of mutual coupling depending on the distance between each element. A decoupling structure is proposed which consists on a grounded vertical copper plane between every patch. To achieve a better isolation, these new elements introduce an extra coupling. The experimental results indicate that using a Copper Vertical Plane Structure the Coupling can be reduced in 3dB.
