MIMO Antenna Design for 5G Satellite Millimeter-Wave Communications

Abstract

In This paper, a new Mimo antenna design is proposed for 5G Nano satellite millimeter-wave communications operating at 60 GHz. The micro strip patch antenna is designed using RT Duroid substrate overall size 9 $\times$ 8$\times$ 0.254 mm3, that has a dielectric constant of 2.2, and 0.254 mm thickness. For the parameter studies, first we truncated one patch corner; this technic is therefore used to reduce the size of our proposed Mimo antenna. Then, for adapting the (S22) at the resonance frequency we removed a rectangular slot in the middle on the three elements of Mimo antenna output patch. The performance of Mimo antenna (ANT3) exhibits a good simulation results, good impudence matching, where the return loss (S11) at 61.5 GHz has equal to −41.09 dB, and the transmission coefficient (S21) of −23dB, a VSWR report is equal to 1.03, and a high gain value of 11.29 dBi. The 5G capacity transmission rates were improved using our proposed antenna.
