Abstract
An antenna or set of antennae for a wireless device is provided by embedding the antennae into the battery case or generally the surface area of a wireless phone. The antenna connections are through the battery'"'"'s connections to the wireless device. The antenna can be located at the back surface of the battery or the rear surface of a wireless phone, facing away from the user. An RF shielding device can be embedded into the battery and configured in relation to the antenna such that the RF field intensity and the consequent specific absorption rate for the user is lowered while the outgoing signals of the wireless device remain fully adequate for the function of the wireless device. This feature is preserved for a multi-band operation because a digital phase shifter is used between two radiating antennae. An external case is used as a complement to the wireless phone.
