Arranjo de antenas MIMO aplicado à 5ª geração de redes móveis

Abstract

With the growing popularization of technology and the increased need for connection between people and "things," creating ways to improve mobile communications has become a point of various research in the area. Based on this evolution and the need to improve users' experience in the technological environment, the fifth generation of mobile technology emerged, popularly known as 5G, which aims to increase transmission capacity, improve gain, reduce communications network system responseHowever, the existence of interference and attenuation in the system increasingly needs to be minimized. For this, methods have been studied such as the use of multiple input and multiple output antennas (MIMO), which help improve the gain, bandwidth and, consequently, the channel capacity of the antennas. An example of the application of this technique is through the use of rectangular microstrip antennas, which are low cost and easy to build, making their reproduction more accessible. In this context, this work aims to demonstrate the importance of using this technique for the fifth generation mobile technology, in terms of performance improvement, when compared to the use of simple antennas. Thus, it is expected that this work has significant contributions that can be implemented in favor of the expansion of mobile communications.
