The growing demand for high-speed, short-range wireless communication in 5G networks calls for compact and efficient antenna solutions. This study presents the design, simulation, and performance evaluation of a rectangular microstrip patch antenna optimised to resonate at 46.2 GHz. The antenna was designed using numerical calculations in Python and modelled with FEKO simulation software, employing RT Duroid as the substrate material with a dielectric constant of 2.2 and a substrate thickness of 0.4 mm. The calculated patch dimensions were 1.9268 mm in length and 2.5579 mm in width. The following parameters were analysed; return loss, gain, VSWR, radiation patterns, and directivity. The simulation results showed a return loss of -23.59 dB, a VSWR of 1.156, a gain of 10 dB, and a directivity of 9.5 dB, confirming excellent impedance matching, high radiation efficiency, and strong directional performance. These are within standard benchmarks and also compared favourably with existing literature. The findings demonstrate that the proposed antenna is a practical and high-performing solution for nextgeneration 5G wireless communication systems.
