A study of 5G antennas in a mobile terminal

This paper presents a simulation-based study for the number and placement of 5G antenna elements in mobile terminals operating in the frequency range from 1 to 6 GHz. Different antenna configurations are compared in terms of the ergodic capacity (bit/s/Hz) in the spatial multiplexing mode. According to the results, ergodic channel capacity increases almost linearly with the number of antenna elements at least up to 10 elements in a device at all the studied frequency.
