Electronic device and antenna structure thereof

An electronic device, comprising:

• a hinge;
• a first body and a second body being rotatable with respect to each other via the hinge, wherein a conductive housing in the first body includes an open slot and a corner adjacent to the hinge, and the open slot being adjacent to the corner;
• and
• a feed element forming an antenna structure with the open slot, and including
• a substrate including a first surface and a second surface opposite to each other, the second surface facing the conductive housing,
• a grounding portion and a shorting portion electrically connected with the conductive housing, respectively;
• orthographic projections of the grounding portion and the shorting portion on the conductive housing being located at two opposite sides of the open slot, respectively,
• a first feeding portion disposed at the first surface and having a feeding point, the first feeding portion being electrically connected with the conductive housing via the shorting portion, and
• a second feeding portion disposed at the first surface and electrically connected with the first feeding portion, the second feeding portion and the grounding portion being separated by a first coupling gap, orthographic projections, of the first feeding portion and the second feeding portion on the conductive housing being within the open slot,
• wherein the first feeding portion and the second feeding portion resonate the antenna structure, and the antenna structure operates at a first frequency band via a first path formed by the open slot, and operates at a second frequency band via a second path formed by the first feeding portion and the second feeding portion.
