The antenna 10 comprises a plastic frame 11, a metal skin 12 attached to the outer surface of the plastic frame 11, and an antenna module 13. The plastic frame 11 may serve as a middle frame of the terminal device 100. The antenna module 13 is disposed at a side of the plastic frame 11 facing away from the metal skin 12. The metal cover 12 may be exposed outside the terminal device 100, and the antenna module 13 may be accommodated inside the terminal device 100. The antenna module 13 is provided with a feeding point S, the antenna module 13 is separated from the metal skin 12 by a plastic frame 11, and the antenna module 13 is coupled to the metal skin 12 for feeding.

In addition, the metal skin 12 has less material consumption and reduced cost. In addition, the metal skin 12 can be coupled with the antenna module 13 for feeding, and has the function of an antenna radiator for tuning and expanding the antenna frequency band.

In one embodiment, the antenna module 13 may be provided with a plurality of antenna modules 13, and the plurality of antenna modules 13 may receive and transmit electromagnetic waves with different wavelengths, so as to satisfy a multi-antenna application scenario.
