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.

Abstract: An antenna structure and a wireless communication device having the antenna structure are provided, the antenna structure includes a metal frame, a feeding portion, a first ground portion, and a second ground portion. The metal frame defines a first gap, a second gap, and a third gap, the metal frame between the first gap and the second gap forms a first radiating portion, the metal frame between the first gap and the third gap and the metal frame on a side of the third gap cooperatively form a second radiating portion, the metal frame on a side of the second gap forms a third radiating portion. The feeding portion is connected to the first radiating portion. The first ground portion is apart from the feeding portion and connected to the first radiating portion. The second ground portion closes to the second gap and is connected to the third radiating portion.

Abstract: An antenna structure includes a frame portion and a feeding portion. The frame portion is provided with a first gap and a second gap. The first gap and the second gap penetrate and divide the frame portion into a first radiating portion, a second radiating portion, and a third radiating portion. The feeding portion is arranged on the first radiating portion adjacent to the second gap. One end of the feeding portion is electrically coupled to the first radiating portion, and the other end of the feeding portion is electrically coupled to a feeding point to feed current to the first radiating portion. The second radiating portion and/or the third radiating portion is provided with a side slot. A radiation frequency band of the second radiating portion and/or the third radiating portion where the side slot is located is adjusted by adjusting the length of the side slot.
