Internal antenna having surface-mounted receptacle

An internal antenna having a surface-mounted receptacle, comprising:

• a printed circuit board configured such that a receptacle is surface-mounted on an upper surface thereof;
• a radiator connected to the printed circuit board;
• and
• a frame configured such that the printed circuit board and the radiator are mounted thereto,
• wherein the printed circuit board is configured to electrically connect the upper surface and a lower surface thereof partially,
• the frame has a vertically cut surface and a horizontally cut surface formed such that a predetermined portion in the frame forms a stair shape, and has two grooves formed along the vertically cut surface and horizontally cut surface, and
• the radiator has a feeding terminal and a ground terminal to be fitted into each of the two grooves formed in the frame, and
• wherein the feeding terminal and ground terminal of the radiator are inserted and fitted into each of the two grooves formed along the vertically cut surface and horizontally cut surface of the frame, the printed circuit board is mounted on and fastened to the horizontally cut surface of the frame to contact the feeding and ground terminals of the radiator to the lower surface of the printed circuit board, and the feeding terminal of the radiator is connected electrically with the receptacle of the printed circuit board.
