摘要：This paper proposes the design of a MIMO Array 2x1 element microstrip antenna for a fifth generation (5G) technology system at a frequency of 3.5 GHz. The antenna is designed using RT-Duroid R5880 substrate type with dielectric constant (εr) = 2.2 , thickness (h) = 1.57 mm and loss tan (tan ) = 0.0009. MIMO array is applied to increase the gain and directivity of the proposed antenna. The proposed MIMO antenna design has been successfully simulated with a reflection coefficient of -22 dB, an isolation coefficient of -78 dB and a gain of 12 dB at a frequency of 3.5 GHz. Furthermore, the bandwidth of the proposed antenna is 0.32 GHz (3.32 GHz � 3.68 GHz). The application of 2x1 MIMO arrays succeeded in increasing gain and bandwidth up to 47.05 % and 91.07% compared to single element antennas. The correlation and directivity of the proposed MIMO antenna has a good value with an Envelope Correlation Coefficient (ECC) of 0.0005 and a Diversity Gain (DG) of 10 dB at a frequency of 3.5 GHz. The proposed antenna design has worked according to the criteria and can be used as a recommendation as a receiving antenna in the fifth generation (5G) communication system.
