Exemplary embodiments are disclosed of dual-band multiple-input multiple-output (MIMO) antennas. In an exemplary embodiment, an antenna generally includes a circuit board, a first antenna radiating element positioned on the circuit board, a second antenna radiating element positioned on the circuit board, and at least two antenna feeding elements extending from the circuit board. Each of the at least two antenna feeding elements is electrically connected with a different one of the first and second antenna elements.

Dual band multiple-input multiple-output antennas

A flexible inverted 'F' antenna (PIFA) is shown. The flexible PIFA is not only applicable to flat surfaces, but it can be applied to curved surfaces, both convex and concave, without degrading performance. The flexible PIFA can also be used close to living bodies or to a metal surface without detuning. The flexible PIFA is formed from a flexible printed circuit board (PCB) having a metal layer on one side and over which a cover layer is positioned. The flexible PCB is folded, on its reverse side, around a flexible dielectric element with the covered metal layer facing outward to form a metal conducting service, an impedance matching stub and a ground plate. An adhesive layer forms a portion of the ground plate that is not in contact with the dielectric element. This adhesive layer is applied against the desired surface. A coaxial cable is electrically coupled to corresponding feed and ground tabs at the short circuit plate portion of the flexible PIFA.
