1. An assembly comprising:

  • a hand-held communications device having a ground plane circuit and having a rear side directed away from an intended user of said communications device;

    a driven element operatively coupled to the communications device, said driven element radiating a transmitted signal;

    a conductor element disposed upon the communications device and having a major surface directed toward the user, said conductor element disposed between the driven element and a user of the communications device, said conductor element coupled to the ground plane circuit; and

    a radiation-shielding structure for blocking at least a portion of a user-directed transmitted signal of the communication device, said radiation-shielding structure disposed upon the major surface of the conductor element so that the radiation-shielding structure is between the conductor element and the user, and said radiation-shielding structure including a plurality of conductive particles disposed within a non-conductive matrix.
