NFC mechanicss of communication are applied to the neck such as file transmission, mobile payment, public transport, medical treatment & health extensively in recent years Domain.Business of the NFC mobile phone as mass transit card, subway card particularly has been opened in public transport field, domestic many cities, People no longer need to be lined up to supplement with money to mass transit card, also no longer needs to use mass transit card to take subway, public transport.
Meanwhile people rapidly increase the usage degree of electronic product, particularly smart mobile phone, plus high-power chip, The reasons such as the use of polycaryon processor cause a big bottleneck of the electronic equipment heating problem as Current electronic industry development.Cause This, the heat dissipation design of electronic equipment also seems increasingly important.And the usual all positions of the radiating module of NFC antenna module and electronic equipment In the inner side of casting of electronic device, so the performance design of the compatibility of the two, coexistence problems to whole product, test manufacture positioning etc. has Very important status.
Utility model content
The purpose of this utility model be exactly in order to provided the defects of overcoming above-mentioned prior art to exist it is a kind of it is simple in construction, It is compact, it is economical and practical, have the radiating of quick heat radiating performance and good near-field communication function and the antenna that near-field communication is two-in-one concurrently Module.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of radiating and the two-in-one antenna modules of near-field communication, the antenna modules are logical including being from bottom to top laid in successively The induction antenna layer and heat dissipating layer on device interior circuit layer are interrogated, described induction antenna layer includes being successively set on communication apparatus Ferrite layer and coil layer on interior circuit layers, the region being in contact with induction antenna layer on described heat dissipating layer offer water Flat translot, in the operating condition, described heat dissipating layer carry out near field magnetic coupling by horizontal translot and induction antenna layer, will believe Number amplification after, then with the external world carry out near-field communication.
Width of the described horizontal translot along heat dissipating layer is laid on heat dissipating layer from left to right or from right to left.
The length of described horizontal translot is the 1/3-1/2 of heat dissipating layer width.
The width of described horizontal translot is 2-5mm.
The area of described heat dissipating layer is more than the area of induction antenna layer, to obtain preferable heat conduction and heat radiation effect.
Described induction antenna layer is located at the underface of horizontal translot on heat dissipating layer, to ensure best coupling effect.
The material of described heat dissipating layer is metal material.
Described heat dissipating layer is copper foil or aluminium foil.
The shell material of described communication apparatus is non-conductive non-magnet material at least in region corresponding to antenna modules.
Described induction antenna layer is driven by the circuit layer of communication apparatus, and then realizes NFC communication functions.
In real work, communication apparatus interior circuit layers send ac signal to coil layer, form closed-loop path Ring current, in the presence of ferrite layer, the alternating current will on the direction perpendicular to coil layer and close to radiating Layer side forms stronger magnetic field.Now, the heat dissipating layer with horizontal translot structure directly over coil layer can be with the magnetic Field carries out magnetic coupling, and then induced-current can be produced on heat dissipating layer.Similarly, the induced-current can produce sensing magnetic again , and then electromagnetic induction is carried out with external device, complete near-field communication.At the same time, communication apparatus interior circuit layers and sensing Heat caused by antenna stack etc., the lower region of temperature can be promptly directed in the presence of heat dissipating layer, while outwardly dissipated Send out.So, communication apparatus has and also can quickly radiated while good near-field communication.
Compared with prior art, the utility model overall structure is simple, compact, using the radiating with horizontal translot structure Layer can carry out near field magnetic coupling with sensing antenna stack, signal is carried out near-field communication with extraneous again after amplifying so that communication Equipment can quick heat radiating while, also there is better near-field communication function, processing is simple, and economic and practical is good, tool There is good application prospect.
