A microstrip patch antenna resonating at 1.575 GHz was modeled and simulated in CST Studio Suite in three configurations. Two architectures were studied: a MIMO configuration composed of 6 elements, and a second structure with 8 elements (4×2), designed for GPS applications. A phase-shift study revealed that the latter configuration was the most efficient, achieving a gain of 8 dBi and a reflection coefficient S11 better than −10 dB. This solution helps overcome the limitations of conventional GPS systems, especially in urban environments, and effectively meets the requirements of 5G networks for intelligent mobility.frAntenne intelligente, MIMO, 5G, CST Studio Suite, Géolocalisation, Patch micro-ruban, GPS, Beamforming, S11, GainSmart antenna, MIMO, 5G, CST Studio Suite, Geolocation, Microstrip patch antenna, GPS, BeamformingThesis
