MIMO (Multi-Input Multi-Output) systems have become one of the most studied topics in research be-cause of its ability to increase the spectral efficiency (capacity) over a limited bandwidth. The use of multi-ple antennas leads to an additional dimension in the degree of multiple access to the network compared to the single-antenna case and thus offers an effective solution to increasing data rates for future generations of cellular radiotelephony. In this paper, a 2 x 6 MIMO antenna array structure is presented. HFSS soft-ware is used in the simulation process of the designed antenna. The proposed structure covers the fre-quency band ranging from 1.2 to 6.3 GHz. A thin Rogers 5880 RT substrate of 54 x 60 x 0.4 mm3 is used to design the antenna. The behavior of the MIMO antenna has been studied as a function of a certain number of parameters, namely: the distance separated MIMO antenna elements and the radius of the slot in the patch. The results show that the variation of these parameters affects the isolation. The design of the pro-posed antenna is done, by fixing the distance at λ/2 and the radius at 2.25 mm, in such a manner we get a high isolation between the radiating elements of about – 83.8 dB which will provide a reliable anti-interference performance for the system. The outcomes make this antenna a potential candidate for 5G application at the sub 6 GHz band. |
