CSRR backed compact two-port, dual-band MIMO antenna for mm-wave applications

This study presents a symmetrical two-element Multiple-Input Multiple-Output (MIMO) antenna that exploits a feasible spectrum for 5G millimetre structure on the ground plane.It is attained to one additional operating mode at 24 GHz. A Rogers RT5880 substrate material is used in the construction of the proposed MIMO antenna. This substrate material has dimensions of 0.064 lambda x 0.012 lambda (at 24 GHz), a thickness of 0.8 mm, and a dielectric constant of 2.2.The results of the testing suggest that the antenna has the potential to span a frequency range that stretches from 23.5 to 25.5 GHz (6.1%) and from 34.2 to 36.4 (8.2%) GHz. In addition, the antenna does not need the usage of a sophisticated decoupling structure in order to achieve an inter-port isolation of higher than 15 dB between the antenna components across both bands. This is possible since the antenna is dual-banded. The results that were obtained from the measurement of the antenna after it was put through its paces are as follows. The components that make up this diagram are merged together to form a single entity. An envelope correlation coefficient of less than 0.005 and a channel capacity loss of less than 0.315 bits/s/Hz are the results of analysing the diversity performance characteristics. These results are totally compatible with the criteria and norms that are taken into consideration to be acceptable as a whole. The findings demonstrate that the design can successfully transmit millimetre waves at 5G rates, which was the goal of the study.
