The present disclosure provides a terminal device. The terminal device comprises a feed, a metal frame, a coupling plate, and a radiation plate. An outer side of the metal frame is provided with at least two grooves, each groove is provided with two first through holes, and each of the groove is provided with a radiation plate and a coupling plate, and the metal frame is grounded. The coupling plate in each groove is disposed between the radiation plate and the bottom of the groove, and the coupling plate is provided with two second through holes. Each radiation plate is provided with two antenna feed points, the feed is connected to an antenna feed point through a first through hole and a second through hole, and the antenna feed point, the first through hole, and the second through hole in each groove correspond one to one. The metal frame, the coupling plate, and the radiation plate are not in contact with each other and are filled with a non-conductive material, and the area of the radiation plate is smaller than the area of the coupling plate.
