- Abstract
In this paper, a new broadband microstrip slot antenna operated at millimeter wave (mm-wave) band and utilized in 5G systems is introduced. The suggested radiator composed of a rectangular slot etched on the ground plane with internal embedded L-shaped stub inside it. Parametric studies were done on three major dimensions of the proposed antenna to study the effect of these parameters on the bandwidth. The proposed radiator operates from 23.78 GHz to 50 GHz with impedance bandwidth of 26.22 GHz. Therefore, the proposed antenna supports the new 5G millimeter wave bands that cover (24.25 - 29.5) GHz, (37 - 43.5) GHz, (45.5 - 47) GHz, and (47.2 - 48.2) GHz bands. The gain of the proposed slot antenna element varies from 4.3 dBi to 8 dBi with average value of 5.5 dBi. A novel 6×6 multiple-input multiple-output (MIMO) structure is introduced. The proposed MIMO radiator was fabricated on Roger4003C substrate. The isolation between each two adjacent antennas is below -35dB over the required 5G mm-Wave spectrum. The value of the envelope correlation coefficient between the antenna elements does not exceed 0.011. The diversity gains (DG) between the radiators exceeds 9.94 dB. There is a good agreement between the simulated and the measured results.
