US Patent 10389010 Antenna structure and wireless communication device using same

An antenna structure includes a metallic member, a feed portion, a ground portion and a radiating portion. 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, which are in communication with the slot and extend across the front frame. A straight portion of the front frame between the first gap and the second gap forms a radiating section. The feed portion and the ground portion are electrically connected to the radiating section. Current enters the radiating section from the feed portion. The current flows through the radiating section and towards the second gap. The radiating portion obtains current from the radiating section by coupling. The radiating section and the radiating portion generate radiation signals in two different frequency bands. A wireless communication device using the antenna structure is provided.
