Abstract
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.
