A multi-input, multi-output antenna comprises an electrically conductive body, generally symmetrical about a plane of symmetry. An active port (Feed point) is located on the plane, a first parasitic port (1) is located on one side of the plane, and a second parasitic port (2) is located on the other side of the plane, generally symmetrically to the first parasitic port. An RF module is connected to the active port (Feed point), and each of the first and second parasitic ports (1, 2) are connected to a respective load (6, 7) of variable impedance. The design of the antenna is intended for beamspace MIMO that can be effectively incorporated in a compact, low-cost mobile terminal.
