Abstract

The present invention provides a ferrite antenna, a mobile terminal and a preparation method of a ferrite antenna. The preparation method comprises: pouring ferrite slurry into a die, wherein the line figure of the die corresponding to the ferrite antenna is provided with a raised line; performing preliminary drying forming processing of the ferrite slurry in the die in a first temperature range, and forming a ferrite sheet with a groove arranged in the surface through initial solidification after the first time; performing dying processing of the ferrite sheet through initial solidification in a second temperature range, and obtaining a completely solidified ferrite sheet after the second time; performing coating film crushing pressure processing of the surface without a groove of the completely solidified ferrite sheet, and obtaining a finished product ferrite sheet; and filling conductive materials into the groove of the finished product ferrite sheet, and forming a conductive line layer. Therefore, the groove of the ferrite sheet is filled with the conductive materials to form the conductive line layer so as to effectively reduce the thickness of the ferrite antenna and allow the ferrite antenna to better satisfy the requirement of the mobile terminal on the structure.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a ferrite antenna, a mobile terminal and a preparation method of the ferrite antenna. Background technique [0002] NFC (Near Field Communication, Near Field Communication) is a non-contact identification and interconnection technology for short-distance secure communication. Because NFC has the advantages of fast processing speed, high security, and low power consumption, NFC technology is widely used in mobile The payment field has a wide range of application scenarios, and the NFC function of mobile terminals such as mobile phones is realized through NFC antennas. [0003] The current NFC antenna is usually designed with a coil circuit FPC (Flexible Printed Circuit, flexible circuit board) through double-sided tape and ferrite to provide electromagnetic shielding bonding fixed, so the thickness of the NFC antenna is FPC, double-sided The total stacking thickness of glue...
