An antenna structure and a terminal device are provided. The antenna structure is applied to a terminal device with a curved screen. The antenna structure includes a radiator and a feeding point. The radiator has a first break and a second break located on different sides, the first break is on one curved side edge, and the second break is on one non-curved side edge. The feeding point is electrically connected to the radiator and located between the first break and the second break. A length of a radiation arm between the feeding point and the first break is less than a length of a radiation arm between the feeding point and the second break. The antenna structure has a low-frequency radiation mode that utilizes the radiation arm between the feeding point and the second break for radiation.

Antenna structure and terminal device

An antenna assembly and a terminal device are provided. The antenna assembly includes a conductive frame, a circuit board, and a metal conductor. The metal conductor has one end connected to a feed point on the circuit board and the other end connected to a switch on the circuit board and the conductive frame. The switch is configured to adjust a radiation frequency band of the antenna assembly. A radiator of the antenna assembly comprises the metal conductor and the conductive frame.
