1. An antenna structure of an electronic device, the electronic device comprising a metal frame, comprising: at least one radiation portion formed by a partial portion of the metal frame; a first feed source, a second feed source and a third feed source being spaced at intervals and feeding current signals to the at least one radiation portion; a first grounding portion; and a second grounding portion spaced from the first grounding portion, wherein a first end of the first grounding portion and a first end of the second grounding portion electrically connect to the at least one radiation portion, and a second end of the first grounding portion and a second end of the second grounding portion are grounded, wherein the metal frame defines a first gap and a second gap, the first gap and the second gap cut off the metal frame, and the at least one radiation portion is formed by the metal frame between the first gap and the second gap, the first feed source electrically connects to one end of the at least one radiation portion close to the first gap, the second feed source electrically connects to one end of the at least one radiation portion close to the second gap, and the third feed source is arranged between the first feed source and the second feed source, and electrically connects to the at least one radiation portion.
