    Resumen

    MIMO technology enables high-data rates in wireless devices to allow from speech and video calls up to streaming media and web browsing all over a common platform. MIMO technology needs M antennas both in transmission and reception. Since the space in a wireless device is limited, including M antennas is a challenge. To face such challenge, two MIMO systems are proposed. A first one using a multiband antenna and two small non-resonant elements, one for 824MHz-960MHz and another for 1710MHz-2170MHz and a second system which comprises two small non-resonant elements operating in the frequency region 824-960MHz and two identical elements operating at 1710-2170MHz. The size of each of the non-resonant elements is only 5 mm × 5 mm × 5mm. The MIMO systems are analyzed in terms of bandwidth, efficiency, correlation, and multiplexing efficiency as well as capacity. Capacity is measured in a reverberation chamber considering a free-space Rayleigh scenario and also including the effect of a phantom head and hand. The results reveal that small non-resonant elements can be used to minimize volume while preserving performance in terms of MIMO parameters.
