Abstract
An antenna structure includes a housing, a first feed portion, a first ground portion, and a second ground portion. The housing defines a slot, a first groove, and a gap. The housing is divided into a first portion and a second portion by the slot, the first groove, and the gap. The first portion is further divided into a first radiating portion and a second radiating portion by the first feed portion. A first portion of the housing extending from the first feed portion to the first gap forms the first radiating portion. A second portion of the housing extending from the first feed portion to the groove forms the second radiating portion. The second radiating portion is shorter than the second portion. The second portion is shorter than the first radiating portion. The first portion activates a first operation mode and the second portion activates a second operation mode.
