  4. Abstract:
  5. In this paper, it is shown that an optimum coupling between massive MIMO elements improves the SNR for each user in 5G downlink mode. It is assumed that a massive MIMO base station with 64 compact antennas with sub-wavelength spacing (0.37λ) serves 8 user equipments. With proper design of antennas couplings, the mean received SNR of users improves from 4 to 7 dB. Different coupling values are implemented for a sample patch antenna at 28 GHz with a slot on substrate between adjacent patch elements to control the element coupling. The whole system is simulated in MATLAB, with 5G millimeter-wave channel characteristics and OFDM modulation
