Problems solved by technology

Due to the complex manufacturing process of the ferrite magnetic antenna and the very fragile ferrite magnetic material, the processing is very difficult and the manufacturing cost is very high
Ferrite magnetic materials are very easy to break during processing. It is very difficult to improve the transmitting and receiving sensitivity of the antenna by increasing the size of ferrite magnetic materials.

Abstract

The invention discloses an induction and coupling antenna structure of a mobile phone SIM card. The induction and coupling antenna structure of the mobile phone SIM card comprises PCB lines printed on an SIM card body, rigid sheet bodies made of metal material and magnetic ferrite sheets. The magnetic ferrite sheets are placed on the SIM card, and all the rigid sheet bodies are made into a steel net to cover the magnetic ferrite sheets. The two ends of each the rigid sheet body are correspondingly connected between the two adjacent PCB lines in sequence respectively. The magnetic ferrite sheets are contained between the rigid sheet bodies and the PCB lines. According to the induction and coupling antenna structure of the mobile phone SIM card, PCB wiring is arranged on the SIM card, the PCB wiring and the steel net or bound metal wires welded to the wiring form a coil loop, the magnetic ferrite sheets are added in the middle of the coil, and then an equivalent ferrite magnetic antenna is naturally formed. The antenna structure has the advantages of being simple in machining technology and low in cost; because ferrite magnetic materials with the size largened can be adopted, both the transmitting sensitivity and the receiving sensitivity of the antenna can be greatly improved.

Description

technical field [0001] The invention relates to a mobile phone smart card, in particular to an inductive coupling antenna structure of a mobile phone SIM card. Background technique [0002] NFC is the abbreviation of Near Field Communication, that is, short-range wireless communication technology. NFC, jointly developed by Philips and Sony, is a contactless identification and interconnection technology that enables short-range wireless communication between mobile devices, consumer electronics, PCs and smart control tools. [0003] NFC technology mostly uses the 13.56M frequency standard for the technical field of near-field communication. Under this standard system, the international standard ISO14443 has been formed. Most domestic payment platforms centered on the China UnionPay payment system have adopted the international standard ISO14443. And use the 13.56MHZ frequency standard for the technical standard of mobile payment. [0004] Under this system standard, the mai...
