Description
Technical field
The utility model belongs to antenna technical field, is related to a kind of NFC antenna based on PDS techniques.
Background technology
PDS is a kind of printing antenna for mobile phone (bat printing) technique, and conductive silver paste is mainly coated to workpiece surface by it, so
Afterwards by multi-sheet printed silver paste, to form conductive stereo circuit.PDS is made of by directly printing electrically conductive ink in interior of mobile phone
" PDS (PBINTI NG Direct Structure) " technology of antenna, it is that one kind can lift less radio-frequency (RF) feature
Built-in antenna manufacture method, is only to form environmentally friendly electroless using electrically conductive ink on the printing position of specific plastic material
The patent technology of coating, lifting RF features and reliability.By PDS techniques plastic casing upper surface printed antenna figure
Sample, the antenna pattern needs to extend sideways to lower surface from plastic casing, the feed point position connection being connected with circuit board of mobile phone, so that
Realize antenna and circuit board successful connection.PDS advantage is that circuit can be directly printed, and is not required to special laser modified material, can
Cost is greatly reduced, circuit turn-on can be all realized on corner, the structure of through hole than more intractable in Antenna Design.
With the determination of mobile payment standard, many high-end intelligent artifacts start standard configuration mobile payment function.With movement
The product of NFC payment functions needs NFC chip and NFC antenna.NFC antenna is based on RFID REIDs, to use
The hardware handles scheme communicated, and the school for the communication instruction completion data transfer procedure for passing through processor are done in coupling matching to transformer altogether
Test, hardware environment is adjusted by match circuit and designed and produced successfully by RFID modulation treatments.NFC antenna is one
Near-field coupling antenna is planted, magnetic-coupled form is used, i.e., by the way of coil coupling.NFC system can be carried to user
For mode card, read-write mode and point-to-point three kinds of services, communication distance is shorter, safe, simple to operate.It is existing
The present, with a wide range of popularization of smart mobile phone, NFC user also gradually increases.At present, mobile phone does thinner and thinner, equally to NFC antenna
Thickness requirement also more and more higher.Traditional NFC antenna, is made up of FPC antenna plus ferrite, the gross thickness phase of antenna
The meeting answered is thicker, and the antenna needs laminating process, considerably increases the scrappage of NFC antenna, and efficiency is low.
Utility model content
