Abstract

Considering the demands of fifth generation mobile communication system technology (5G), this paper proposes the development of a compact triangular patch antenna with slots, designed to operate in the frequency bands used by this wireless communication system in Brazil. Starting from the initial design equations, the proposed structure was simulated using ANSYS HFSS (High Frequency Structure Simulator) software and then built and validated experimentally through measurements at IFPB's Telecommunications Measurements Laboratory. The results obtained show the effect of miniaturization. The antenna achieved a multiband effect, operating at 2.3 GHz, 3.5 GHz and 4.9 GHz, the same frequencies allocated for use by the 5G system in Brazil, showing its potential for application in mobile devices with greater spectral efficiency.
