Radiation redirecting external case for portable communication device and antenna embedded in battery of portable communication device

An apparatus, comprising:

• an external case configured to be disposed with a wireless device, the external case having an antenna,
• the antenna that couples to radiation from an internal antenna of the wireless device such that a specific absorption rate (SAR) of the wireless device is reduced without substantially adversely affecting a total radiation power (TRP) of the wireless device, when the external case is coupled to the wireless device and when the wireless device is operational.

A method comprising:

• passively coupling radiation, from an internal antenna of a wireless device having a case, at an external case when the external case is coupled to the wireless device and when the wireless device is operational, the external case being separate from the case of the wireless device;
• and
• redirecting the radiation away from a user of the wireless device when the external case is coupled to the wireless device and when the wireless device is operational.
