Abstract
An antenna structure includes a housing, a first feed source, a second feed source, and a resonance circuit. The housing includes a first and a second radiator spaced to each other and grounded. The first feed source feeds current into the first radiator to activate a first mode, a second mode, and a third mode to generate radiation signals in a first frequency band, a second frequency band, and a third frequency band. The second feed source feeds current into the second radiator to activate a fourth mode to generate radiation signals in a fourth frequency band. The resonance circuit adjusts a radiation frequency band of the second radiator according to an impedance of the resonance circuit. The first radiator adjusts the third mode according to the radiation frequency band of the second radiator. A wireless communication device employing the antenna structure is also provided.
