Title: A shielding device
IPC: H04B1/38
Filed: 1996-10-24
Abstract: 1. A shield for shielding radiation from a communication device, having an antenna, the shield comprising an electrically conductive element adapted to be located at a position spaced from the antenna, the electrically conductive element carrying a resilient finger, the resilient finger being adapted to touch the antenna of the communication device. 2. A shield for shielding radiation from a communication device, comprising an electrically conductive element and a means for mounting, a base plate made of conductive material, supporting means, a means to mount the base plate in position relative to the antenna of the communication device a slider, and a cover, the slider being located between the base plate and the cover, part of the slider being accessible through the cover, to effect sliding of the slider, the slider being movable between a retracted position and an extended position, the slider, when in the extended petition, having an electrically conductive element extending beyond the base plate and the cover. 3. A shield according to Claim 2, characterized in that the electrically conductive element carrying a resilient finger, the resilient finger being adapted to touch the antenna of the communication device in the extended position. 4. A shield according to Claim 2 or 3, characterized in that the shield being movable to an extended position, the shield being located to one side of the antenna of the communication device so that, in use, the shield is not between the antenna of the communication device and a person using the communication device. 5. A case for a communication device, comprising a shield, being movable between a retracted position and an extended position, the shield being located to one side of the antenna of the communication device so that, in use, the shield is not between the antenna of the communication device and a person using the communication device. 6. A communication device having an antenna, and a shielding element having an electrically conductive element movable from a retracted position to an extended position, the shielding element having an electrically conductive element which, when the shielding element is in the extended position, touches the antenna. 7. A mobile telephone having an antenna and a shield located to one side of or behind the antenna so that the shield is not located between the antenna and the head of a person using the telephone. 8. A shield for shielding radiation from a communication device having an antenna, the shield comprising an electrically conductive element adapted to be located at a position spaced from the antenna, the electrically conductive element being adapted to touch the antenna of the communication device, or carrying a resilient finger, the resilient finger being adapted to touch the antenna, the shield being slidable so that the protruding length of the shield may be adjusted. 9. A shield for a communication device, said device comprising an electrically conductive element, supporting means slidably supporting the conductive element, means to mount the supporting means in position relative to the communication device and means to slide the electrically conductive element from a retracted position to an extended position, the electrically conductive element, when in the extended position, having a predetermined position relative to the antenna of the communication device and the shield, being movable and in an extended position, the shield being located to one side of the antenna of the communication device so that, in use, the shield is not between the antenna of the communication device and a person using the communication device. 10. A shield according to Claim 9, characterized in that the electrically conductive element carrying a resilient finger, the resilient finger being adapted to touch the antenna of the communication device, when electrically conductive element in the extended position.
