Design and Analysis of Fractal Type MIMO Radiator for the Applications of Sub 6-GHz 5G Systems

In this structure, a fractal type-based MIMO radiator is designed with a size 55 mm × 30 mm using the substrate of FR-4. The S-parameters of the current design ranging 2.8–4.5 GHz with wider impedance bandwidth 1.7 GHz. The return loss and isolation parameters are − 40 dB and − 42 dB at the resonating frequency. In order to minimizing the isolation among the patches spacing is considered as 3.0 mm. By using, various parametric approaches identified that greater reduction in mutual coupling the element spacing is optimized. The technique of monopole ground plane improved the enhancement in the bandwidth and improve antenna parameters. The MIMO parameters of the proposed system are within the acceptable values to use in real time applications.
