It should be noted that：Similar label and letter represent similar terms in following accompanying drawing, therefore, once a certain Xiang Yi
It is defined in individual accompanying drawing, then do not need it is further discussed in subsequent accompanying drawing.
It is arranged in various boards and takies product sky to solve NFC antenna present in prior art and Bluetooth antenna
Between larger problem it is proposed that a kind of circuit board with NFC antenna and Bluetooth antenna, as shown in figure 1, include insulated substrate,
Magnetic material 7, the NFC antenna 1 being printed on insulated substrate and Bluetooth antenna 2 and be welded on NFC chip 3 on insulated substrate,
NFC antenna 1 and Bluetooth antenna 2 are arranged in the same surface of insulated substrate, NFC chip 3 pass through the NFC antenna 1 connecting and its
Communicated between his NFC device, magnetic material 7 covers the surface of NFC chip 3 and NFC antenna 1.Its specific coverage effect
Can be as shown in Figure 2.
Wherein, NFC (i.e. near-field communication) is a kind of radiotechnics of short distance high frequency, runs on 10 in 13.56MHz frequency
In cm distance.Its transmission speed has 106Kbit/ second, 212Kbit/ second or three kinds of 424Kbit/ second.Current near-field communication is
By becoming ISO/IECIS18092 international standard, ECMA-340 standard and ETSITS102190 standard.NFC is using active and quilt
Dynamic two kinds of read modes.
NFC technology is to be developed by non-contact radio-frequency identification (RFID) and the Technology Integration that interconnects,
Combining induction card reader, icah wavw and point-to-point function on one chip, can be in short distance and compatible equipment
It is identified data to exchange.But operating frequency is 13.56MHz. must be changed using the user of this mobile-phone payment scheme
Special mobile phone.This technology is widely used in Japan and Korea S at present.
As RFID, NFC information is also the electromagnetic induction coupled modes transmission by radio frequency section in frequency spectrum, but
Still there is very big difference between the two.First, NFC is a kind of wireless connection skill providing and easily, safely, rapidly communicating
Art, its transmission range is less than RFID.Secondly, NFC is compatible with existing contactless smart card technology, has become as and is got more and more
The official standard that leading firm supports.Again, NFC or one kind closely connection protocol, provide various equipment rooms easily, peace
Entirely, rapidly and automatically communicate.Compared with other connected modes in wireless world, NFC is a kind of in-plant secret communication
Mode.
NFC, infrared ray, bluetooth are all non-contact transmission mode, and they have each different technical characteristics, can be used for
Various different purposes, its technology does not have good and bad difference in itself.
The built-in NFC chip of NFC mobile phone, further increases the work(of data double-way transmission than the RFID being originally only used as label use
Can, this progress makes it be more suitable for for electronic money payment；Particularly RFID institute irrealizable, be mutually authenticated and
Dynamic encryption and disposable key (OTP) can be realized on NFC.NFC technique supports multiple applications, including mobile payment and friendship
Easily, peer-to-peer communication and mobile in message reference etc..By NFC mobile phone, people can pass through in any place, any time
Any equipment, the entertainment service being intentionally got with them and transaction are linked together, thus completing to pay the bill, obtain poster information
Deng.NFC device can serve as contact type intelligent card, the read write line terminal of the smart card and equipment data transfer chain to equipment
Road, its application can be divided mainly into following four fundamental type：For payment and booking, it is used for electronic bill, is used for smart media
And be used for exchanging, transmission data.
Support NFC equipment can under actively or passively pattern exchange data.In the passive mode, start NFC communication
Equipment, also referred to as NFC initiating equipment (main equipment), in whole communication process provide radiofrequency field (RF-field), it is permissible
Select 106kbps, 212kbps or 424kbps one of which transmission speed, transmit data to another equipment.Another sets
Standby referred to as NFC target device (from equipment) is it is not necessary to produce radiofrequency field, and modulates (load modulation) technology using load,
Initiating equipment back can be passed data with same speed.This communication mechanism with based on ISO14443A, MIFARE and FeliCa
Contact type intelligent card is compatible, and therefore, NFC initiating equipment in the passive mode, can be connected and initialization procedure with identical
Detection contact type intelligent card or NFC target device, and set up contact therewith.
NFC antenna 1 is a kind of near-field coupling antenna, and because 13.56Mhz wavelength is very long, and reading/writing distance is very short, suitably
Coupled modes are magnetic couplings, and coil is suitable coupled modes.
Specifically, magnetic material 7 is to shield interference for NFC antenna 1 anti-metal, strengthens induced signal receiving sensitivity
Magnetic film, can reduce the absorption to signal magnetic field for the metal material, specially reduce the signal between NFC antenna 1 and Bluetooth antenna 2
Interference.In a specific embodiment of the present utility model, this magnetic material 7 can be Ferrite Material, and Ferrite Material is
A kind of functional composite material based on electromagnetic wave absorption, can eliminate the roundtrip of electromagnetic wave in shielding cavity, reduce miscellaneous
The interference to equipment of itself for the ripple, also effectively prevents electromagnetic radiation to the interference of surrounding devices and personnel and injury, is a kind of elimination
The advanced means of Contamination of Electromagnetic Wave.Ferrite Material can also be effectively increased distance of reaction by increasing magnetic field intensity.
Due to NFC antenna 1 and Bluetooth antenna 2 transmission is all radiofrequency signal, if directly by NFC antenna 1 and bluetooth sky
Line 2 is arranged in the problem to reduce circuit board real estate on same circuit board, may produce the problem of radiofrequency signal interference,
Therefore, by covering magnetic material 7 on the surface of NFC antenna 2 and NFC chip 3, Bluetooth antenna 2 can be prevented effectively to NFC
Interference, avoid the interference to bluetooth for the signal that NFC produces simultaneously, improve the reliability of radio signal transmission.
Further, magnetic material 7 can be bonded on insulated substrate, in such manner, it is possible to by material simply with low cost
Magnetic material 7 is fixed on insulated substrate material, it is to avoid magnetic material 7 rocks on insulated substrate surface, impact high-frequency signal
Reliability.
In a specific embodiment of the present utility model, circuit board is flexible PCB, and flexible PCB is with polyamides
Imines or polyester film have a height reliability for one kind that base material is made, excellent flexible printed circuit, have distribution
The feature that density is high, lightweight, thickness of thin, bending property are good.
Take the area of circuit board, in a specific embodiment of the present utility model, bluetooth in order to reduce Bluetooth antenna 2
Antenna 2 is inverted-L antenna.
For the ease of setting up communication connection with cell phone mainboard, bluetooth earphone mainboard etc., concrete at one of the present utility model
In embodiment, circuit board also includes the NFC chip contact point 4 being connected with NFC chip and the Bluetooth antenna being connected with Bluetooth antenna
Contact point 5, NFC chip contact point 4 is connected with external circuitses for NFC chip 3 to carry out NFC signal transmission, and Bluetooth antenna connects
