Abstract
Shield apparatus for portable wireless telephones or personal communication apparatus includes electromagnetic radio frequency radiation absorption and blocking materials disposed about the antenna and any other electromagnetic transmitting portion of the wireless portable telephone or personal communication apparatus adjacent to, or in the direction of, the user of the wireless communication apparatus. The absorption and blocking or shield area absorbs and blocks the radiation and protects the user from the radiation, and metallic elements redirect the electromagnetic radiation away from the user and extend the transmission range of the communication apparatus. The portion of the antenna remote from the user is free or open, and thus permeable to the electromagnetic radiation, typically in the microwave frequency band, so that the communication signal may be appropriately transmitted from the wireless portable telephone or personal communication apparatus, and may be received by the hand held portable telephone or personal communication apparatus.
