A Compact MIMO Antenna for 5G NR Frequency Bands n257/n258/n261 Under Millimeter-Wave Communication

Abstract

In this article, a compact, planar, 4-port ultra-wideband (UWB) multiple-input–multiple-output (MIMO) antenna is conceived for fifth-generation millimeter-wave applications. The suggested MIMO antenna architecture consists of four identical hexagonal-shaped slotted ground plane and four microstrip line feeds. The MIMO antenna's four components are arranged orthogonally to one another to provide a high level of inter-element isolation. The antenna prototype is constructed on a (12.5×12.5×0.8 mm³) Duroid 5880 substrate having a relative dielectric constant (ϵ_rsub) of 2.2 and loss tangent (tanδ) of 0.0009. Diversity characteristics such as envelope correlation coefficient (ECC), and diversity gain are determined to validate the proposed MIMO antenna's work qualities. The isolation is more than 18 dB, indicating that the proposed design is suitable for use as a quad-port MIMO antenna. The proposed MIMO antenna has a 30.47% impedance bandwidth throughout the frequency range of 26.7 GHz to 36.3 GHz, making it suitable for 5G New Radiofrequency bands n257/n258/n261 under Millimeter-Wave Communication. Positive correlations between the simulated and experimental findings are observed.
