Abstract: A communications device includes an antenna including a radiator and a ground. A NFC circuit and the radiator are coupled at a first node; a non-NFC circuit and the radiator are coupled at a second node by using a non-NFC feeding path, the non-NFC feeding path includes two capacitors with different capacitances. The radiator forms a first part between the first node and the second node. The radiator includes a second part, one end of the second part is coupled to the ground, and the other end is connected to the first part. An electrical length of the second part is less than a quarter wavelength corresponding to a resonance frequency of a low frequency signal, and the electrical length of the second part is greater than an electrical length of the first part. The radiator includes a third part from the first node to an endpoint of the radiator.
