Integrated antenna structure

An integrated antenna structure, comprising:

• a frame, surrounding and defining an accommodation space, the frame comprising an annular portion and a plurality of separation portions, the annular portion having a first side and a second side opposite to each other, the separation portions being disposed on the first side;
• a circuit board, disposed in the accommodation space;
• at least one first antenna radiator, comprising a first body and a plurality of first platforms, wherein the first body is disposed on the first side by using a nano molding technology (NMT) and is connected between two adjacent separation portions, the first body at least partially surrounds the accommodation space, the first platforms are connected to the first body and protrude toward the accommodation space, and the first platforms are configured to be electrically connected to the circuit board respectively;
• a support plate, disposed in the accommodation space;
• a battery, disposed on the support plate;
• and
• at least one metal sheet, at least partially disposed on a surface of the support plate and extending along an edge of the support plate, wherein one end of the metal sheet is electrically connected to the circuit board.
