1. An antenna assembly for transmitting a radio signal from a communication device for use by a user, said antenna assembly comprising:

  • an antenna structure, including a driven element and at least one parasitic element, said at least one parasitic element displaced a gap distance from said driven element effective to direct at least a portion of the radio signal into a direction away from the user; and

    a radiation-shielding structure for blocking at least a portion of the radio signal directed toward the user of the communication device, said radiation-shielding structure disposed during use between the antenna structure and the user, said radiation-shielding structure including a radiation-shielding material and a conductive element, said conductive element disposed during use between the radiation-shielding material and the user.
