1. A radio communications device comprising:

  • a processor;

    radio frequency communications circuitry coupled to said processor;

    a ground plane;

    a radio frequency radiator element;

    a feed point electrically coupling the radio frequency radiator element to the radio frequency communications circuitry, the feed point physically contacting the radio frequency radiator element at a feed contact point of the radio frequency radiator element;

    a first ground connector electrically coupling the radio frequency radiator element to the ground plane, the first ground connector electrically coupling the radio frequency radiator element at a first ground contact point of the radio frequency radiator element;

    a switching unit; and

    a second ground connector selectively electrically coupling the radio frequency radiator element to the ground plane through the switching unit, the second ground connector electrically coupling the radio frequency radiator element at a second ground contact point of the radio frequency radiator element, wherein in use the switching unit selectively couples the frequency radiator element to the ground plane depending upon desired operating frequency bands for the radio frequency radiator element.
