A Dual-Band Eight-Element MIMO Antenna Array for Future Ultrathin Mobile Terminals.

An ultrathin dual-band eight-element multiple input-multiple output (MIMO) antenna operating in fifth-generation (5G) 3.4-3.6 GHz and 4.

Minimized Triple-Band Eight-Element Antenna Array for 5G Metal-frame Smartphone Applications.

A multiple-input-multiple-output (MIMO) antenna array for triple-band 5G metal-frame smartphone applications is proposed in this paper. Each single antenna element consists of an S-shaped feeding strip and an L-shaped radiation strip on the metal frame. The dimension of the antenna element is only 6.
