Desenvolvimento e análise de uma matriz de Butler para operação em 26GHz em sistemas de comunicação 5G.

Abstract

This work presents the development and analysis of a Butler matrix designed to operate at 26 GHz, targeting applications in 5G communication systems. Using electromagnetic simulation tools such as Ansys HFSS and Keysight ADS, the project was modeled with the aim of optimizing critical parameters like insertion loss, antenna gain, and phase behavior. The matrix components, including hybrid couplers, crossovers, and phase shifters, were adjusted to ensure the formation of orthogonal beams with high precision. The analysis of results highlighted the need for design adjustments to minimize phase errors and insertion losses, ensuring matrix efficiency in high-frequency networks. This study contributes to the advancement of beamforming technologies applied to 5G, emphasizing the importance of an optimized approach for millimeter-wave operation.
