Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to an NFC antenna and a mobile terminal with the NFC antenna. Background technique

[0002] For existing mobile terminals, some ferrites are directly mounted on the metal casing, and the magnetic field energy of the NFC (Near Field Communication) antenna can only be transferred between the NFC antenna and the ferrite, but cannot radiate to the metal casing. external, resulting in inability to transmit and receive signals. There are also some NFC antennas installed on the metal casing, and the ferrite is installed on the NFC antenna. Since the metal casing has a screen for the signal, the ability of the NFC antenna to receive signals is poor. In order to solve the above problems, the area of ​​the NFC antenna and the magnetic sheet can only be increased, and the length of the slot can be increased, which not only cannot control the size of the volume, but also increases...
