Abstract: An RF shielding device for mobile devices includes a conductive grid having horizontal and vertical wire traces in electrical contact with each other; a conductive trace disposed around the perimeter of the conductive grid, the conductive trace being in electrical contact with both ends of each of the horizontal and vertical wire traces; a first insulating film disposed on a top surface of the conductive grid; and a second insulating film disposed on a bottom surface of the conductive grid and the conductive trace. The first insulating film and the second insulating film are of a transparent material. The first and second insulating films are transparent, thus allowing viewing of the display of a mobile device on which the RF shielding device is disposed. The vertical and horizontal wire traces are spaced to form a grid that is opaque to signals in the frequency ranges utilized for mobile communication.

Abstract: An RF shielding device for application to mobile devices includes an RF blocking screen material configured to cover a front face of the mobile device. The screen material includes a grounding material that contacts a body portion of the mobile device for grounding the screen material to the mobile device. The RF shielding device allows proper operation of a touchscreen interface. The RF shielding device may be configured as a self-adhesive material dimensioned to cover a substantial portion of the front face of the mobile device. Alternatively, the RF shielding device may be constructed as a case or protective shell.
