An antenna structure includes a housing and a feeding source. The housing forms a radiating portion, a first coupling portion, and a second coupling portion. The first coupling portion and the second coupling portion are grounded. The feeding source is electrically connected to the radiating portion for feeding current to the radiating portion and divides the radiating portion into a first radiating section and a second radiating section. When the feeding source supplies current, the current flows through the first radiating section and is coupled to the first coupling portion to activate a first operation mode and a second operation mode. When the feeding source supplies current, the current flows through the second radiating section and is coupled to the second coupling portion to activate a third operation mode and a fourth operation mode.

Antenna structure and wireless communication device using same

An antenna structure includes a side frame, a first feed portion, a second feed portion, and a first ground portion. The side frame defines a first gap and a second gap. The side frame is divided into a first radiating portion by the first gap and the second gap. When the first feed portion supplies current, the current flows through a first resonance section and is grounded through the first ground portion to activate a first operating mode and a second operating mode. When the first feed portion supplies current, the current flows through a second resonance section and is grounded through the second feed portion to activate a third operating mode. When the second feed portion supplies current, the current flows through the second resonance section and the first resonance section, and is grounded through the first ground portion to activate a fourth operating mode.

Antenna structure and wireless communication device using the same

An antenna module includes a holder, a first feed portion, a second feed portion, a first antenna unit, and a second antenna unit. The holder includes a top surface, an end surface, and a side surface. The first feed portion is positioned on the top surface. The second feed portion is positioned on the top surface and is spaced from the first feed portion. The first antenna unit is positioned on the top surface and the end surface, and is electrically connected to the first feed portion. The second antenna unit is spaced from the second antenna unit and is positioned on the top surface and the side surface. The second antenna unit is electrically connected to the second feed portion. The first feed portion and the second feed portion respectively feed current to the first antenna unit and the second antenna unit.

Antenna module and wireless communication device using same

An antenna structure includes an antenna holder, a feed unit, a grounding unit, a first radiating unit, a second radiating unit, a third radiating unit, a parasitic unit, and a coupling unit. The feed unit and the grounding unit are positioned on the antenna holder and are spaced apart from each other. The first radiating unit and the third radiating unit are both electrically connected to the feed unit. The parasitic unit is electrically connected to the grounding unit. The first radiating unit couples with the second radiating unit and the parasitic unit. The second radiating unit further couples with the coupling unit and is grounded through the coupling unit.
