Abstract
An wireless communication device has a housing with an exterior surface that is designed to face a user when the wireless communication device is transmitting a radio frequency signal. The communication device includes an antenna disposed inside the housing for emitting a radio frequency signal. A metal-dielectric structure resonates to reflect the radio frequency signal. The metal-dielectric structure is located between the antenna and the exterior surface at a position wherein he metal-dielectric structure traps and reflects the radio frequency signal thereby reducing a specific absorption rate of the wireless communication device.
