Abstract
The invention provides an NFC (near field communication) antenna which comprises an antenna route. A first NFC feed point is formed at an end of the antenna route; a second NFC feed point is formed at the other end of the antenna route; the first NFC feed point and the second NFC feed point are encircled in coils formed by the antenna route. The invention further provides an intelligent device with the NFC antenna. The NFC antenna and the intelligent device have the advantages that routing modes of the coils in the NFC antenna are different from the traditional routing modes, the two feed points of the antenna are arranged inside regions enclosed by the antenna route and can be directly connected with two antenna connecting ports of a chip, accordingly, spaces can be saved to a great extent on the premise that the NFC performance is not deteriorated, and the NFC antenna and the intelligent device are applicable to the insides of intelligent bracelets with narrow and small spaces.

Technical field
The present invention relates to NFC antenna design field, in particular it relates to NFC antenna and comprise the intelligent apparatus of NFC antenna,
Especially comprise the Intelligent bracelet of NFC antenna.
Background technology
NFC English full name Near Field Communication, near field wireless telecommunications.It is to be sent out by PHILIPS Co.
Rise, the well-known manufacturer such as Nokia, Sony combine the wireless technology promoted mainly.Fitted in by many companies, university and user
Li Liao Pan European Union, it is intended to the open architecture of exploitation NFC, and promote its application in mobile phone.NFC is by non-contact radio-frequency
(RFID) technology and the Technology Integration that interconnects develop, integrated induction formula card reader, vicarious card on single chips
With point-to-point function, can be identified with various compatible equipments in short-range and data exchange.This technology is initial
Simply RFID technique and the simple merging of data acquisition technology, developed and become a kind of short-distance wireless communication technology,
Growth momentum is the rapidest.
Therefore, it is necessary to propose the NFC antenna of the Intelligent bracelet of a kind of applicable small space.
Summary of the invention
For defect of the prior art, it is an object of the invention to provide a kind of NFC antenna and the intelligence comprising NFC antenna
Device.
