Generación de diagramas de radiación para arreglos de antenas cúbicas usadas en mimo-3d

Currently, with the emergence of fifth generation (5G) mobile systems, a significant change is expected in the impact that technology has given our daily lives. In order to guarantee adequate reliability in wireless telecommunications systems and to increase transmission speeds, several techniques have been presented, among which are antenna arrangements. For 5G we propose the so-called massive MIMO configured in three-dimensional antenna arrays. There are several detection techniques when using antenna arrays. The detection technique that presents a better compromise between implementation complexity and performance is known as beamforming, with which the radiation beam from the antenna array can be pointed in a specific direction. For a better understanding of the behavior of this detection technique and its importance in future fifth generation networks, in this work we plot radiation diagrams for antennas arranged in a three-dimensional arrangement. For this we implement an algorithm in Matlab and analyze the geometric structure of one of the faces of the antenna array. A mathematical expression was found to determine the beam-steering vector of this face. Using Matlab, we generated the radiation diagrams in different scenarios and it was observed that when the number of antennas is increased, the radiation beam increases its directivity, the more antennas, the more directive. This means that interference is better eliminated.
