Abstract:
An electromagnetic radiation protection device of a mobile phone installed at one side of an antenna of a mobile phone, characterized in that:the device comprises an electromagnetic wave absorbing piece, a dielectric plate, an electronic joint loop, a negative electrode lead, the electromagnetic wave absorbing piece is installed at the side near said antenna, said dielectric plate serves to isolate said electromagnetic wave absorbing piece and said antenna, a lower end of said electromagnetic wave absorbing piece is structure to an input of a joint of said electronic joint loop, an output of the joint of said electronic joint loop is connected to said negative electrode lead, another end of said negative electrode lead is connected to said negative electrode of the power source of a mobile phone;in practical using, the electromagnetic radiation from the mobile phone to user's head will be reduced effectively, and the threaten of brain harm is also reduced.
