Abstract

This manuscript investigates the effectiveness of a mixed polarization configuration Multiple-Input and Multiple Output (MIMO) antenna system (MPC-MEVIO) that uses dual polarized antennas in the base station and single polarized antennas in mobile terminals based on a performance comparison using dual polarized antennas for both the transmitter and receiver antennas (POL-MIMO). The performance is evaluated based on the results of 2×2 MIMO measurements conducted in the 2.4-GHz band. The investigation focuses on the dependency of the element spacing of an MT antenna on the correlation, received power, and channel capacity. Even when a single polarized antenna is used in a MT, keeping the antenna element spacing at 0.4λ, the capacity is comparable to that of POL-MEVIO in this environment.
