Abstract
The invention discloses a long-distance communication full-surrounding type disconnected RFID (radio frequency identification) tag. A chip and a communication antenna are arranged on the front side of a substrate. A spiral antenna is arranged on the chip and is correspondingly connected with the communication end of the chip. The communication antenna is a strip-shaped dipole antenna. The middle section of the communication antenna fully surrounds the periphery of the spiral antenna in an O-shaped manner. Two ends of the communication antenna are arranged at two ends of the front side of the substrate in an impulse waveform manner after intersecting. The spiral antenna is in wireless connection with the communication antenna through electromagnetic coupling. A heat-resisting covering layer covers the front side of the substrate, the chip, the spiral antenna and the communication antenna completely. A metal reflection plate is mounted on the reverse side of the substrate. A disconnected structure is formed between the chip and the communication antenna through addition of the spiral antenna, so that requirements on component processing accuracy and connection stability are reduced, and production efficiency is improved; electromagnetic coupling losses of the communication antenna and the spiral antenna are reduced through addition of the metal reflection plate, so that communication distance of the RFID tag is increased.
Description
Technical field
The present invention relates to a kind of electronic tag, particularly relate to a kind of long apart from the full encirclement type Non-connecting electronic tag of communication.
Background technology
Along with the deep development of wireless radio-frequency, the application of electronic tag (i.e. RFID) is more and more extensive, and no matter industrial product orientation is followed the tracks of, or the bus position in life shows in real time, all will use electronic tag.Stable connection degree between the machining precision of electronic tag, parts requires also more and more higher, and the quality of the communication distance of electronic tag also its practical application effect of direct relation.
Existing electronic tag, is substantially all made up of substrate, chip and communication antenna, and chip and communication antenna are all located on substrate, and the communication terminal of chip is connected with communication antenna correspondence.Different according to its power supply, electronic tag is divided into active electronic label and passive electronic label, and the former relies on the cell powers carried, and volume is comparatively large, power consumption is comparatively large, and the latter relies on communication antenna to obtain power supply from electronic label read/write, and volume is little, power consumption is little.All there is following problem in above-mentioned traditional electronic tag: the communication terminal of chip is connected with communication antenna correspondence, so have higher requirement to the machining precision of parts and stable connection degree, not so easily cause the later stage assembling parts or junction cannot to disconnect and cause electronic tag normally to use, will inevitably production efficiency be reduced like this; Because the power of electronic tag is very little, and communication antenna is omnibearing when signal transmission, loses with the rightabout signal forming energy of electronic label read/write, makes its communication distance not enough, is difficult to meet increasing long distance communicating requirement; Communication antenna many employings linear pattern chip aerial, requires that it has enough length, there is unconformable problem for the electronic tag that whole length requirement is little while guarantee signal intensity.These defects all limit the deep application of electronic tag and further developing of radio-frequency technique.
Summary of the invention
Object of the present invention is just to provide a kind of long apart from the full encirclement type Non-connecting electronic tag of communication to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The full encirclement type Non-connecting electronic tag of long distance communication of the present invention comprises substrate, chip, communication antenna, helical aerials, metallic reflection plate and resistance to thermal blanket, described chip and described communication antenna are all located on the front of described substrate, described helical aerials to be located on described chip and correspondingly with the communication terminal of described chip to be connected, described communication antenna is bar shaped dipole antenna, the stage casing of described communication antenna is surrounded on the periphery of described helical aerials entirely in " O " shape, be located at the two ends, front of described substrate respectively in pulse waveform after the two ends intersection of described communication antenna, by electromagnetic coupled wireless connections between described helical aerials and described communication antenna, described resistance to thermal blanket is by the front of described substrate, described chip, described helical aerials and described communication antenna all cover, described metallic reflection plate is installed on the back side of described substrate.
As preferably, described resistance to thermal blanket is polyphenylene sulfide resin lipid layer.
As preferably, described helical aerials is be printed on copper wire on described chip or copper sheet.
For ease of producing, described metallic reflection plate is pasted on the back side of described substrate by bonding agent.
Particularly, described metallic reflection plate is aluminium reflecting plate.Described bonding agent is epoxy resin.
Beneficial effect of the present invention is:
The present invention, by increasing helical aerials, makes the structure forming Non-connecting between chip and communication antenna, greatly reduces machining precision and the requirement of stable connection degree of parts, makes electronic tag be convenient to processing, improves production efficiency; By increasing metallic reflection plate, reducing the loss of communication antenna and helical aerials electromagnetic coupled, adding the communication distance of electronic tag, be convenient to application; By adopting bar shaped dipole antenna as communication antenna, and adopting full encirclement and pulse waveform structure, while meeting signal intensity, reducing the length of electronic tag, be applicable to small size object exterior pasting and use.

Fig. 2 is the A-A cutaway view Amplified image in Fig. 1;
Fig. 3 is the vertical view after the full encirclement type Non-connecting electronic tag of long distance communication of the present invention removes resistance to thermal blanket.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As Fig. 1, shown in Fig. 2 and Fig. 3, the full encirclement type Non-connecting electronic tag of long distance communication of the present invention comprises substrate 2, chip 5, communication antenna 4, helical aerials 6, metallic reflection plate 1 and resistance to thermal blanket 3, chip 5 and communication antenna 4 are all located on the front of substrate 2, helical aerials 6 to be located on chip 5 and correspondingly with the communication terminal of chip 5 to be connected, communication antenna 4 is bar shaped dipole antenna, the stage casing of communication antenna 4 is surrounded on the periphery of helical aerials 6 entirely in " O " shape, be located at the two ends, front of substrate 2 respectively in pulse waveform after the two ends intersection of communication antenna 4, by electromagnetic coupled wireless connections between helical aerials 6 and communication antenna 4, the back side being installed on substrate 2 pasted by metallic reflection plate 1 by epoxy resin (not shown).Above-mentioned pulse waveform is the waveform of electronic pulse signal, be specifically as follows multiple dense arrangement shape, it is the dense arrangement shape at straight line+right angle in this example, and narrow gradually from inside to outside according to the shape of substrate 2, make whole communication antenna 4 form the shape of circle or nearly circle ellipse, be applicable to circle or oval electronic tag.No matter whether contact between helical aerials 6 with communication antenna 4, all can not change electromagnetic coupled wireless connections relation between the two, so low to the requirement on machining accuracy of parts.Communication antenna 4 is pasted on the front of substrate 2 by epoxy resin (not shown).
