The concept of mantle cloaking is applied to suppress the undesired cross-coupling among the antenna elements of two tightly spaced and interleaved phased antenna arrays used in 5G wireless applications, which in turn enhances the radiation characteristics of the arrays. It is demonstrated that the specifically designed metasurface cloaks decouple the antenna elements of two different arrays and enable to restore the original radiation patterns of the isolated arrays, such that the antenna arrays placed in close proximity of each other can radiate independently for a wide range of beam scanning angles. This paper illustrates microstrip antenna arrays with elliptically shaped metasurface cloaks integrated in printed technology. The simulation results validate the fact that by encasing the elements of the arrays with their respective cloaks, it is not only possible to eliminate the cross coupling but also to restore the radiation properties of the antenna arrays within the frequency bands of their operation.
