Abstract
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.
