Ten element single-band mimo antenna for 5g smartphones

A ten element dual band multiple-input multiple-output (MIMO) antenna for a smartphone, comprising:

• a substrate having a top side, a bottom side, a first side wall, a second side wall opposite the first side wall, a third side wall perpendicular to the first side wall and a fourth side wall opposite to the third side wall;
• ten single element dual band antennas, wherein a first five antennas of the ten single element dual band antennas are spaced evenly along an outer surface of the first side wall and a second five antennas of the ten single element dual band antennas are spaced evenly along an outer surface of the second side wall, wherein each single element dual band antenna includes a meandered slot line having a first arm and a second arm, wherein the first arm and the second arm are connected by a straight leg;
• ten T-shaped feed structures, wherein a first five of the ten T-shaped feed structures are located an inner surface of the first side wall and a second five of the ten T-shaped feed structures are located on an inner surface of the second side wall, wherein each T-shaped feed structure is located parallel to the straight leg and centered between the first arm and the second arm of a respective antenna;
• wherein each T-shaped feed structure is connected through the substrate to a feed port located on the bottom side;
• a ground plane located on the bottom side of the substrate, wherein the first arm and the second arm are connected to the ground plane;
• and
• wherein each antenna of the ten element dual band MIMO antenna is configured to radiate at a resonant frequency of about 3.5 GHz in response to an electrical signal applied to its respective feed port.
