An antenna structure includes a carrier body, a circuit board, a metal coupling sheet, a first grounding part, a second grounding part, and a metal frame. A first slot and a second slot are between the metal frame and the carrier body after the parts mentioned above are assembled. The metal coupling sheet, the first grounding part, and the first slot form a first communication path. The first communication path forms a low-frequency resonance and a high-frequency resonance as well, so that the antenna structure is applied to a four bands GSM850/900/1800/1900. The metal coupling sheet, the second grounding part, and the second slot form a second communication path. The second communication path forms the WCDMA2100 resonance, so that the antenna structure is applied to a five bands 850/900/1800/1900/2100. |

1. An antenna structure including:
a carrier body including a top side, a bottom side, a right side, and a left side, the right side connected to the top side and the bottom side, the left side connected to the top side and the bottom side; a circuit board assembled with the carrier body; a metal coupling sheet electrically connected to the circuit board and arranged at the bottom side of the carrier body; a first grounding part connected to the left side of the carrier body and electrically connected to the circuit board; a second grounding part connected to the left side of the carrier body and below the first grounding part and electrically connected to the circuit board; and a metal frame assembled with the carrier body and at the top side, the bottom side, the right side, and the left side, the metal frame electrically connected to the first grounding part and the second grounding part, wherein a first slot is between the metal frame and the right side; a second slot is between the metal frame, below the left side, and the bottom side; the metal coupling sheet, the first grounding part, and the first slot form a first communication path; the metal coupling sheet, the second grounding part, and the second slot form a second communication path. |
