Mobile phone capable of reducing an electromagnetic specific absorption rate in human bodies

摘要

A mobile phone capable of reducing an electromagnetic SAR in human bodies includes a base and a cover disposed on the base. The base includes an antenna for transmitting and receiving electromagnetic waves. The cover includes a screen and buttons. Electromagnetic absorbing materials having electric or magnetic loss are applied on the cover to mitigate electromagnetic waves radiating from the antenna into the user. Moreover, a meandered planar inverted-F antenna is attached to the back of the circuit board near the bottom of the base, which can generate a lower near field at the user's side than those in other directions, thereby reducing the electromagnetic specific absorption rate of the mobile phone in human bodies.
