Abstract: This disclosure provides a loop antenna, including a substrate, and a grounding portion, a matching portion, a first radiating portion, a second radiating portion, and a feed portion that are located on the substrate. The first radiating portion includes a first radiating segment and a second radiating segment. The grounding portion includes a first grounding segment and a second grounding segment. The second grounding segment is perpendicularly connected to a first end of the first grounding segment. The matching portion is connected to a second end of the first grounding segment and the first radiating segment. The first radiating segment extends from the matching portion away from the first grounding segment. The second radiating segment extends from the first radiating segment toward the second grounding segment. There is a coupling gap between the second radiating portion and the second radiating segment, and the second radiating portion extends toward the second grounding segment. The feed portion is located between an end of the second radiating portion and the second grounding segment to receive and send a feed signal.
