Abstract
An antenna structure includes a metallic member, a radiating portion, 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, a second gap, and a fourth 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; another portion between the second gap and the fourth gap forms a third radiating section. The radiating portion crosses the second gap and connects to the first radiating section and the third radiating section; an end of the second matching circuit electrically connects to the radiating portion, the other end connects to a ground. A wireless communication device using the antenna structure is provided.
