1. A wireless dongle, comprising:
a circuit board having a first front edge, a first rear edge opposite to the first front edge, a first left edge, and a first right edge opposite to the first left edge;
a connector disposed on a middle of a front of the circuit board, the connector projecting beyond a middle of the first front edge of the circuit board;
a wireless module disposed on a middle area and a left area of the circuit board, the connector being electrically connected to the wireless module; and
a printed antenna positioned at a right area of the circuit board, the printed antenna being a monopole antenna, the wireless module being connected between the connector and the printed antenna, the wireless module being disposed between the printed antenna and the first left edge of the circuit board, the printed antenna being disposed between the wireless module and the first right edge of the circuit board, the printed antenna being arranged away from the connector, the printed antenna having:
a feed-in section positioned close to the first rear edge of the circuit board, the feed-in section being connected to a right rear corner of the wireless module; and
a radiation section horizontally extended rightward from a right end of the feed-in section along the first rear edge of the circuit board, then being bent frontward and extended towards the first front edge of the circuit board, later being bent rightward and horizontally extended towards the first right edge of the circuit board and being further bent rearward and longitudinally extended close to the first rear edge of the circuit board;
wherein a second rear edge of the radiation section is separated from the first rear edge of the circuit board by a first clearance, a second front edge of the radiation section is separated from the first front edge of the circuit board by a second clearance, an outer edge of the radiation section is separated from the first right edge of the circuit board by the first clearance, the second clearance is greater than the first clearance, an extending path of a front portion of the radiation section forms in an inverted U shape, and a tail end of the radiation section is located at a right rear corner of the circuit board.
