Design Of 4x4 MIMO Antenna For 5G Applications

The paper discusses the design of a patch antenna for 5G applications, specifically targeting the 5G NR N78 and N79 bands, operating at 4.5GHz. The antenna incorporates a rectangular patch with 2 slots to achieve a structured 4x4 MIMO configuration. The rectangular patch with 2 slots is strategically placed on the microstrip patch antenna, which is fed by a microstrip line. To ensure compatibility with the desired frequency bands, the antenna is designed using FR4 material as the dielectric substrate, characterized by a relative permittivity of 4.4, a height of 1.6mm, and a loss tangent of 0.02. The antenna’s performance, including parameters such as VSWR, Gain, Reflection Coefficient, and Impedance, is thoroughly analysed using HFSS software to ensure compliance with 5G bands N78 and N79 requirements. The detailed parameters and analysis results are included in the paper.
