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.
