ABSTRACT:
A shielding device used on hand-held cellular phones comprises a substantially rectangular shield which extends adjacent to the antenna. A downwardly extending slide arm portion of the shield terminates in a substantially pointed end surface formed by the outer edge of the shield sloping inwardly to engage the inner edge of the slide arm, said outer edge having a notch on the exterior surface thereof. The device also includes a paddle arm portion extending perpendicular to the shield area and then downwardly to terminate in an enlarged paddle engaging the rear of the phone. The shield is mounted to a hand-held cellular phone with the shield area extending vertically upward adjacent to the antenna and the paddle arm extending over the top of the phone and terminating in the rear paddle and the paddle arm extending over the top of the phone. The shield is held in place by an O-ring which surrounds the phone and fits in the notch in the slide arm. The shield comprises polished aluminum while the slide arm and paddle arms are coated with plastic vinyl to enhance friction and prevent scratching of the phone surface. The shielding area deflects a majority of the radiation and simultaneously absorbs whatever is not deflected while physically blocking the user from actual contact with antenna when in use.
