Description
Technical field
The present invention relates to antenna for mobile phone manufacturing technology field, more particularly to a kind of NFC antenna structure based on metal rear shell
And its manufacture method.
Background technology
With the development for moving equipment near field communication (NFC) function at this stage, (Near Field Communicat ion are near by NFC
Apart from wireless communication technique) function will be configured in more handheld devices, and then promote studying to NFC antenna design
Pay attention to more and more.In traditional NFC antenna application, it is typically chosen and FPC, i.e. NFC antenna radiator is placed on battery
Above, while in order to reduce negative effect of the battery for NFC antenna, it is necessary to add lastblock ferrite among FPC and battery.
The rear cover that above-mentioned NFC antenna designing scheme is appropriate only for handheld device is the situation of non-metallic material.But in the recent period with disappearing
The favor of the person of expense, the mobile equipment with metal rear shell come into vogue, this brings the difficulty of bigger to the design of NFC antenna.Cause
When NFC antenna coil is located completely on the inside of complete metal shell, will not only to be produced and NFC days in metal rear shell
The vortex that line current is completely reversed, and since shielding action of the metal rear shell to electromagnetic field to be placed on inside metal-back
NFC antenna can not be detected on the outside of metal rear shell.
After some appropriate processing are carried out to metal rear shell, for example Murata is proposed in patent CN102405556B
A through hole and one are opened in metal rear shell from through hole to the gap at metal rear shell edge.The gap " cut-out " is original
The vortex being completely reversed produced in metal rear shell so that the vortex become with antenna current it is in the same direction have positive work to antenna
Effectively vortex.It is this to overcome above-mentioned metal rear shell to NFC antenna by being effectively vortexed in the same direction caused by cracked gap
Shielding action so that NFC antenna can be detected on the outside of metal rear shell.Although by the method solution for opening hole and gap
Shielding action of the metal rear shell of having determined to NFC antenna, but the through hole opened and gap still have impact on the complete of metal rear shell
Property, this destruction to metal rear shell integrality undoubtedly have impact on the aesthetic feeling and intensity of metal fuselage equipment.
In the patent formula of Murata, NFC antenna coil is below metallic mobile phone rear shell, metallic mobile phone rear shell and NFC
Aerial coil is separately manufactured, is then assembled in mobile phone.
