Along with the development of the world of digital communication and the use of wireless networks that continues to increase, causing the need for bandwidth and capacity in large quantities is needed. Millimeter-wave is one of the 5G supporting technologies that has a large bandwidth capacity, thus making this technology a solution to digital communication problems going forward. The mmWave 5G technology has a wavelength between 1-10 mm and occupies an Extremely High Frequency (EHF) with a range between 30-300 GHz and a large bandwidth. Besides the advantages, 5G communication systems that use mmWave frequencies in the 28 GHz and 60 GHz frequency ranges experience high attenuation and produce small coverage values. Small coverage values in mmWave require a large number of sites to cover areas not covered by mmWave. So that the required power consumption is high and it affects the throughtput and energy efficiency values which are performance measurement parameters in the mmWave 5G communication system. To support performance on mmWave technology, MIMO is a reliable technology because MIMO can increase the capacity of both link capacity and system capacity and can increase reliability so that the coverage value increases. Therefore, it is necessary to analyze and compare the coverage values at the frequencies of 28 GHz and 60 GHz using the MIMO antenna system. Then analyze the performance parameters in the form of throughput and energy efficiency in the mmWave 5G communication system for the 28 GHz and 60 GHz frequencies using the MIMO antenna system. The results of this study indicate that 16 antennas with a frequency of 28 GHz have better energy efficiency performance than 60 GHz with the same antenna. Due to the higher energy efficiency, which is 83.132 km2.Mbps/W, the coverage obtained is wider on 8 antennas with a frequency of 28 GHz, which is .,767 km2. Although 8 antennas frequency 28 GHz. wider coverage, Energy Efficiency remains higher on 32 antennas due to higher throughput of 194.88 Mbps but higher Energy Efficiency on 16 antennas.
