Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in the technology of this area
Personnel are further appreciated by the present invention, but limit the present invention the most in any form.It should be pointed out that, the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, it is also possible to make some changes and improvements.These broadly fall into the present invention
Protection domain.
The NFC antenna cabling form of current main flow is single-ended dual platen, and the form of NFC antenna cabling is improved by the present invention
Become the antenna of dual platen parallel connection cabling form, can be under little space, the most a plurality of cabling, in the feelings not increasing loss
It is effectively improved magnetic field utilization rate under condition and increases performance.
The cabling mode of the coil of inventive antenna is that many cablings are connected to form parallel closed loop structure, plane with parallel way
Antenna at least two walk line parallel closing structure, the cabling in parallel in whole NFC antenna can be whole antenna whole walk
Line, it is also possible to be the part cabling of antenna, can design according to antenna place environment.Use dual platen parallel connection cabling form NFC
Antenna, can effectively increase the magnetic field utilization rate of NFC antenna, can realize preferably NFC performance under less area,
Antenna part is covered by metal or covers state without metal and is all obviously improved NFC performance, and this antenna form can be to use PCB
Or the circuit board material design of FPC etc., compared with traditional cabling, there is good outward appearance, be effectively increased again the radio frequency of antenna
