A Multiple Millimeter-Wave 5G MIMO Antenna Including n257/n258/n259/n260/n261 FR2-Bands with High Diversity Performance

Abstract

This communication focuses on a two-port MIMOWB configuration wide-bandwidth antenna for future 5G high-speed wireless applications radiating electromagnetic energy. The single-port antenna offers impedance bandwidth of 24.50GHz-41.675GHz for HFSS EM-simulator and 23.63GHz-43.13GHz for CST-Microwave Studio EM-simulator. The square-radiating patch radiating EM-wave with the rectangular slot on top-surface & beveled-ground on the bottom surface of dielectric with permittivity 2.20 and thickness 0.787. Also, the compact dimension of the antenna is 12.0 × 15.0 mm2 and the two-port transformed dimensions are 24.0 × 15.0 mm2. The SFD studying surface-current-distribution (SCD) with directional 2-D radiation patterns in n257, n258, n259, n260, and n261 5G-millimeter wave bands infrastructure. The MIMO antenna also offers averaged peak gain of 4.50dBi with high diversity ECC and DG parameters. © 2023 IEEE.
