Abstract: An electronic device and an antenna structure are provided. The electronic device includes a housing and an antenna structure which includes a first radiating element with a first radiating part, a feed part, and a grounding part, a second radiating element with five branches, a grounding element connected to the grounding part, a feed element connected to the feed part, a switching circuit electrically connected to the third branch, and a proximity sensing circuit electrically connected to the fourth branch. The first branch and the second branch intersect at a first branching point, the third branch and the fourth branch intersect at a second branching point. The fifth branch is connected between the first branching point and the second branching point. The first radiating part extends between the first branch and the second branch so the first radiating part and the second radiating element couple with each other.
