ABSTRACT:
A method and apparatus for shielding and/or redirecting radiation from a portable communication device, such as a cellular telephone is provided. In one embodiment, a conductive shield or passive antenna is positioned between the cellular telephone active antenna and the location of the user's head when the cellular telephone is in the operative position. In one embodiment, the shield is configured to reflect radiation in a pattern which is multi-directional. In another configuration, the shield is configured to reflect radiation in a preferred axial direction. Latches or other devices can be used to assure that the shield is positioned and maintained in the desired location. Insulation may be used between the shield and antenna. The shield can be made of a single unitary piece or a plurality of disconnected pieces. The shield may be reconfigurable, e.g., to accommodate a telescoping antenna.
