Abstract
An antenna structure includes a metal housing, a first ground portion, a second ground portion, a first feed source, and a coupling portion. The metal housing includes a front frame, a backboard, and a side frame. The side frame defines a slot and the front frame defines a first groove and a first gap. The slot, the first groove, and the first gap separate a first antenna section from the metal housing. The first ground portion and the second ground portion are both electrically connected to the first antenna section and grounded. One end of the coupling portion is electrically connected to the first feed source. The coupling portion is spaced apart from the first antenna section and current from the first feed source is coupled to the first antenna section through the coupling portion.
