Antenna structure and wireless communication device using the same
An antenna structure includes a housing, a feeding portion, and a connecting portion. The housing defines a gap and a groove. The housing forms a radiating portion and a coupling portion through the gap and the groove. A portion of the housing between the feeding portion and the gap forms a first radiating section. The connecting portion is electrically connected to one end of the coupling portion adjacent to the gap. When the feeding portion supplies current, the current flows through the feeding portion and the first radiating section, and is coupled to the connecting portion through the gap to activate a first operating mode. When the feeding portion supplies current, the current flows through the feeding portion and the first radiating section, and is coupled to the coupling portion through the gap to activate a second operating mode.
