In Fifth Generation (5G) scenarios, several challenges arise, special regarding devices' characterization. Multiple Input Multiple Output (MIMO) antennas will be used in such scenarios and are composed of several elements. Consequently, having several elements di cult for the MIMO antenna characterization, for instance, to identify problems in each antenna element or to select the proper elements to achieve a speci c direction. Since this type of antennas is constituted by many elements, close to each other, to perform beamforming, mutual coupling e ects occur which degrades the MIMO systems. In this sense, techniques to characterize mutual coupling when MIMO antennas are performing beamforming are a necessity. Internet of Things ...
