A 4 × 4 MIMO multiband antenna system with non-resonant elements for smartphone platforms

MIMO technology allows high-data rates in wireless devices. A 4 × 4 MIMO multiband antenna system is proposed using small non-resonant elements placed each one at different corners of a smartphone platform. Electromagnetic analysis as well as an experimental demonstrator show that a compact solution using four non-resonant elements of 10 mm × 3.2 mm × 3.2 mm operating at 824MHz-960MHz and 1710MHz-2400MHz can achieve multiplexing efficiencies of 36% and 53% at each frequency region, respectively.
