An antenna structure includes a metallic member, a first matching circuit, and a second matching circuit. The metallic member includes a front frame, a backboard, and a side frame. The side frame defines a slot. The front frame defines a first gap and a second gap communicating with the slot and extending across the front frame. A portion of the front frame between the first gap and the second gap forms a first radiating section. One end of the first feed portion connects to the first radiating section, the other end connects to a first feed source and a second feed source through an extractor of the first matching circuit; an end of the first radiating section adjacent to the second gap connects to a ground through an third inductor and an third capacitor of the second matching circuit. A wireless communication device using the antenna structure is provided.
