The search for highly linear, efficient systems that can respond to many users has been one of the major concerns of telecommunications operators. In order to respond to all these needs, 5G communication systems have recently started to be developed. The transition to higher frequencies associated with these systems brings with it new challenges in transmitter design, such as the need for antenna arrays. These, in addition to being able to have a large number of elements, also cause the existence of electromagnetic coupling between them, making it very difficult to test them at the circuit level. Thus, this dissertation arises with the objective of developing a platform where it is possible to test, in a fast and userfriendly way, this type of systems. In the second chapter, some characteristics of antenna arrays are presented, reinforcing the need for the platform. The third chapter presents its development, serving as an instruction manual for someone who, in the future, wants to add new features to it. In the fourth chapter, the obtained results are presented and a tutorial is made for a future user of the platform. Finally, the conclusions and future work are presented.
