Abstract
An antenna structure includes a metallic member including a front frame and a side frame. The side frame defines a slot. The front frame defines a second gap and a third gap communicating with the slot and extending across the front frame. A portion of the front frame between the second gap and the third gap forms a first radiating section. Current enters the first radiating section from the first feed portion, flows through the first radiating section and towards the second gap to generate radiation signals in a first frequency band, flows through the first radiating section and towards the third gap to generate radiation signals in a second frequency band, and flows through the first radiating section and towards the second gap and the third gap to generate radiation signals in a third frequency band. A wireless communication device using the antenna structure is provided.
