Abstract
An antenna structure includes a metallic member. 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. The front frame between the first gap and the second gap forms a radiating section. Current enters the radiating section from the first feed portion, the current flows through the radiating section and towards the first gap and the first radiating portion, thus activating radiating signals in a first frequency band; the current flows through the radiating section and towards the first ground portion, thus activating radiating signals in a second frequency band; the current flows through the radiating section and towards the second gap and the second radiating portion, thus activating radiation signals in a third different frequency band. A wireless communication device using the antenna structure is provided.
