Abstract
An antenna structure includes a metallic member and an extending section. 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 radiating section. Current enters the first radiating section from the first feed portion and flows through the first radiating section and towards the first gap and the second gap to generate radiation signals in a first frequency band and a second frequency band; the current flows through the extending section to generate radiation signals in a third frequency band. A wireless communication device using the antenna structure is provided.
