Aog antenna system and mobile terminal

An AOG antenna system, applied to a mobile terminal comprising a 3D glass back cover and a main board opposite to and spaced apart from the 3D glass back cover, wherein the AOG antenna system comprises:

• an Antenna in Package (AiP) disposed between the main board and the 3D glass back cover and electrically connected to the main board;
• and
• a metal antenna formed on a surface of the 3D glass back cover, the metal antenna comprising a first antenna attached to an inner surface of the 3D glass back cover and a second antenna attached to an outer surface of the 3D glass back cover,
• wherein a position of the first antenna corresponds to a position of the AiP and the first antenna is fed with power by coupling to the AiP, and a position the second antenna corresponds to the position of the first antenna and the second antenna is fed with power by coupling to the first antenna.
