Abstract
The utility model belongs to a wireless radio frequency technology, and especially relates to an RFID tag and an antenna system thereof. According to the utility model, a built-in antenna which is arranged in the RFID tag and is connected with an RFID integrated chip is comprised. The RFID tag antenna further comprises an external antenna which is arranged on the surface of the RFID tag and is electrically connected with the built-in antenna. The external antenna is arranged on the casing of the RFID tag, thus the qualities of signal emitting and signal receiving are enhanced. The external antenna makes full use of the size and the shape of the existing RFID tag. Through ingenious structural design, the external antenna has the characteristics of compact structure and reasonable layout, and can generate enough magnetic fields to establish data communication with the RFID tag. Through the combination of the external antenna and the built-in antenna, the antenna generates a high emitting frequency. A high frequency signal has strong penetrability, thus the writing distance and the quality of communication between the RFID integrated chip and the electronic tag are enhanced.
Description
Technical field
The utility model belongs to wireless radio-frequency, relates in particular to a kind of RFID label and antenna system thereof.
Background technology
RFID (Radio Frequency Identification, radio-frequency (RF) identification) passive label is a kind of contactless automatic identification technology.It is identified destination object automatically and obtains related data by radiofrequency signal, need not to set up machinery between recognition system and the specific objective or optics contacts, and identification work more need not manual intervention, so can work in various rugged surroundings.
The RFID passive label mainly is made up of the RFID integrated chip that has cognizance code and connected dual-mode antenna.The read-write facility are outwards launched certain frequency by antenna and are comprised the radiofrequency signal of information, after the RFID passive label enters this magnetic field, receive the radiofrequency signal that the read-write facility send, rely on induction current to obtain enough energy, the RFID passive label is activated, and its internal circuit is returned the corresponding information that is stored in the integrated chip according to the concrete instruction of read-write facility.In general, traditional label antenna design exists uses limitation, and label antenna is designed to circle or the rectangle that the antenna cabling closely is close to usually, when the RFID label is attached on the commodity that have metal, is subjected to the interference of metal easily, is difficult for sense data.On the other hand, antenna must penetrate RFID passive label itself when transmitting signal with the external world, is subjected to the influence of RFID passive label itself and peripheral electromagnetic field, communication distance and the communication quality of weakened to a certain extent RFID integrated chip and electronic tag.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of antenna system of RFID label, to overcome the above-mentioned deficiency of prior art, strengthens the communication quality of RFID integrated chip and electronic tag.
The technical solution adopted in the utility model is:
A kind of RFID label antenna system comprises the built-in aerial that is arranged in the RFID label, is connected with the RFID integrated chip, and as improvement, described RFID label antenna also comprises and is arranged on the external antenna that is electrically connected on the RFID label surface, with described built-in aerial.
Particularly, described built-in aerial is circle or rectangle.
Further, described built-in aerial is arranged on the back side of described RFID integrated chip metal end.
Particularly, described external antenna is stripline antenna, the equal in length of its length and described RFID label.
Further, described external antenna is arranged on the edge of described RFID label outside surface.
The purpose of this utility model also is to provide a kind of RFID label, comprises RFID integrated chip and antenna system, and described antenna system is the RFID label antenna system of top any form.
The beneficial effects of the utility model are: the utility model arranges external antenna by the shell at the RFID label, has strengthened to transmit and receive quality of signals; External antenna has taken full advantage of the size and dimension of existing RFID label, by structural design cleverly, makes external antenna both have compact conformation, rationally distributed characteristics, can produce enough magnetic field again and the RFID label is set up data communication; By the combination of external antenna and built-in aerial, make antenna produce higher transmission frequency, high-frequency signal has very strong penetrability, strengthens reading/writing distance and the communication quality of RFID integrated chip and electronic tag.
Description of drawings
Fig. 1 is the structural representation of the RFID label that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 is the structural representation of the RFID label that provides of the utility model embodiment.For convenience of explanation, only show the part relevant with present embodiment, as shown in the figure:
A kind of RFID label comprises RFID integrated chip 10 and antenna system.This RFID label antenna system comprises the built-in aerial 20 that is arranged in the RFID label, is connected with RFID integrated chip 10 and is arranged on the external antenna 30 that is electrically connected on the RFID label surface, with built-in aerial 20.
As an embodiment of the present utility model, built-in aerial 20 is circle or rectangle.Fig. 1 shows built-in aerial 20 and is the situation of rectangle.And built-in aerial 20 is arranged on the back side of the metal end of RFID integrated chip 10.
As an embodiment of the present utility model, external antenna 30 is stripline antenna, the equal in length of its length and RFID label, and evenly be arranged on the edge of RFID label outside surface.
The utility model arranges external antenna by the shell at the RFID label, has strengthened to transmit and receive quality of signals; External antenna has taken full advantage of the size and dimension of existing RFID label, by structural design cleverly, makes external antenna both have compact conformation, rationally distributed characteristics, can produce enough magnetic field again and the RFID label is set up data communication; By the combination of external antenna and built-in aerial, make antenna produce higher transmission frequency, high-frequency signal has very strong penetrability, strengthens reading/writing distance and the communication quality of RFID integrated chip and electronic tag.
The above only is preferred embodiment of the present utility model, not in order to limit the utility model, although with reference to previous embodiment the utility model has been carried out more detailed explanation, for a person skilled in the art, it still can make amendment or part technical characterictic wherein is equal to replacement the technical scheme that aforementioned each embodiment puts down in writing.All any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
