COMMUNICATIONS DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/027921
Kind Code:
A1
Abstract:
Provided is a communications device comprising: an antenna structure shared by an NFC circuit and a non-NFC circuit, said antenna structure comprising: a radiating body and an antenna ground; the NFC circuit and radiating body are coupled at a first node by means of an NFC feed path; the non-NFC circuit and radiating body are coupled at a second node by means of a non-NFC feed path; the non-NFC feed path comprises a first capacitor and a second capacitor, the capacitance of the second capacitor being greater than the capacitance of the first capacitor; the radiating body forms a first part between the first node and the second node; the radiating body also comprises a second part; one end of the second part is coupled to the ground of the antenna, and the other end is connected to the first part; the electrical length of the second part is shorter than one-fourth of the wavelength corresponding to the resonance frequency of a low-frequency signal, and the electrical length of the second part is greater than the electrical length of the first part; the radiating body also comprises a third part from the first node to the end of the radiating body.
