Abstract
An antenna structure of reduced size but able to operate at multiple frequencies, and applied to an electronic device, includes a housing, a first feed point, a first radiation portion, a first ground point, a second radiation portion, and a second feed point. The housing has at least one portion made of metal material with first and second gaps therein. The housing between first and second gaps forms the first radiation portion. The first feed point feeds current and signal to the first radiation portion. The first ground point is spaced from the first feed point and is grounded through a first inductive element. The second radiation portion is adjacent to the first radiation portion. The second feed point is electrically connected to a second signal point and feeds current and signal to the second radiation portion.
