  • ANTENNA STRUCTURE AND ELECTRONIC DEVICE
    Publication number: 20240030608
    Abstract: An antenna structure and an electronic device are provided. The antenna structure includes a substrate with opposing first and second surfaces, a first radiating element with a first radiating portion and a second radiating portion, a third radiating portion, a feeding portion, and a grounding portion that are connected to the first radiating portion, a second radiating element separate from but coupling with the first radiating portion, a grounding element connected to the grounding portion, and a feeding element. The first radiating portion, the feeding portion, and the grounding portion are disposed on the first surface. The second radiating portion and the third radiating portion are disposed on the second surface. A projected area of the second radiating portion onto the first surface partially overlaps with the feeding portion. A projected area of the third radiating portion onto the first surface partially overlaps with the grounding portion.
