Abstract: An antenna structure includes a housing, a feed portion, a ground portion, a first radiator, and a second radiator. The housing includes a first radiating portion and a second radiating portion. The first radiator and the second radiator are both positioned in the housing. When the feed portion feeds current, the current flows through the first radiating portion and is grounded through the ground portion to activate a first operating mode. When the feed portion feeds current, the current is further coupled to the first radiator through the first radiating portion, and the first radiator activates a second operating mode. When the second radiator feeds current, the second radiator activates a third operating mode. When the second radiator feeds current, the current is further coupled to the second radiating portion through the second radiator, and the second radiating portion activates a fourth operating mode.

Abstract: An antenna structure includes an antenna body, a radiator, a connecting member, and a coupling member. The radiator is a monopole antenna and is spaced apart from the antenna body. The connecting member is electrically connected to the radiator and feeds current signals to the radiator. The coupling member is spaced apart from the antenna body and the antenna body is grounded through the connecting member.

Abstract: An antenna structure includes a housing, four feed sources, a first radiator, a second radiator, and a third radiator. The housing includes a first radiating portion and a second radiating portion. The first to third radiators are positioned in the housing. The first radiator is spaced apart from the second radiator. The four feed sources respectively connect to the first radiating portion, the second radiating portion, the first radiator, and the third radiator. The first radiating portion activates a first operation mode and a second operation mode. The second radiating portion activates a third operation mode. The first to third radiators activate a fourth operation mode, a fifth operation mode, and a sixth operation mode.

Abstract: An antenna structure includes a first feeding source, a second feeding source, and a ring-shaped frame. The ring-shaped frame defines a first radiating portion and a second radiating portion. A current signal flows from the first feeding source to the first radiating portion, the first radiating portion activates a first resonance mode and a second resonance mode simultaneously to generate radiation signals in a first frequency band and a second frequency band. A current signal flows from the second feeding source to the second radiating portion, the second radiating portion activates a third resonance mode and a fourth resonance mode simultaneously to generate radiation signals in a third frequency band and a fourth frequency band. A wireless communication device is also provided.
