Abstract
A kind of new RFID antenna, including copper coil and RFID chip are the utility model is related to, the both ends of the copper coil are electrically connected with the RFID chip respectively, and the RFID chip is located in the copper coil.The RFID antenna, RFID chip is located in copper coil, small, simple in structure, and performance is high, price is low, and easy volume production, easily promote.
Description
Technical field
Antenna technical field is the utility model is related to, more particularly to a kind of new RFID antenna.
Background technology
At present, China RFID markets application distribution is received in identity document and access control, supply chain and inventory tracking, automobile
Take, be antitheft, production control, asset management etc., Radio Frequency Identification Technology be realized by way of twireless radio-frequency communication plug-in reader with
Non-contact bidirectional transfer of information before transponder, is subject to information gathering and identification to target.Current RFID antenna form has button
Formula antenna and paster antenna, have accuracy of identification high, and speed is fast, many advantages, such as, but it is of high cost, volume is big and is not easy volume production
Change.
Utility model content
Based on this, it is necessary to which, for the problem that of high cost, volume is big and is not easy mass production, there is provided a kind of new antenna.
A kind of new RFID antenna, including copper coil and RFID chip, the both ends of the copper coil respectively with the RFID
Chip is electrically connected, and the RFID chip is located in the copper coil.
In one of the embodiments, the length of outer side of the copper coil is 74.50mm, outside width 39.00mm.
In one of the embodiments, inside length the ball 69.50mm, inboard width 34.00mm of the copper coil.
In one of the embodiments, a diameter of 0.10mm of the copper coil.
In one of the embodiments, the copper coil is arranged with insulation film.
Above-mentioned new RFID antenna, RFID chip is located in copper coil, small, simple in structure, and performance is high, price is low,
Easy volume production, easily promote.
Brief description of the drawings
Fig. 1 is the structure diagram of the new RFID antenna of one of embodiment.
Embodiment
To enable the above-mentioned purpose of the utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this
The embodiment of utility model is described in detail.Elaborate many details in order to abundant in the following description
Understand the utility model.But the utility model can be much to implement different from other manner described here, this area
Technical staff can do similar improvement in the case of without prejudice to the utility model connotation, therefore the utility model is from following public affairs
The limitation for the specific embodiment opened.
As shown in Figure 1, a kind of new RFID antenna 10, including copper coil 110 and RFID chip 120, the two of copper coil 110
End is electrically connected with RFID chip 120 respectively, and RFID chip 120 is located in copper coil 110.After card transponder enters magnetic field, lead to
Cross copper coil 110 and receive the radiofrequency signal that plug-in reader is sent, the energy obtained by sensing electric current, which is sent out, is stored in RFID
Product information in chip 120, access time 1-2ms, after plug-in reader reads information and decodes, send to Central Information System and carries out
Related data processing.
Above-mentioned new RFID antenna 10, RFID chip 120 is located in copper coil 110, small, simple in structure, performance height,
Price is low, and easy volume production, easily promote.The RFID antenna is applied to card-like RFID transponders, effectively increases antenna radiation efficiency,
Antenna gain is improved, antenna gain reaches 7.0dB, and accuracy of identification is high, and speed is fast, easy to carry, well-adjusted to environment
Advantage, while material toughness is strong, it is cheap, it is easily installed.Paster antenna is substituted, it is of high cost to avoid paster antenna, without
The problem of easy mass production.
In one of the embodiments, the length of outer side of copper coil 110 is 74.50mm, outside width 39.00mm.
In one of the embodiments, inside length the ball 69.50mm, inboard width 34.00mm of copper coil 110.
In one of the embodiments, 110 a diameter of 0.10mm of copper coil.
In one of the embodiments, copper coil 110 is arranged with insulation film.Insulation film is set to ensure that copper wire is mutual
Between will not short circuit, while copper coil can be attached in plastic cement card and sealed.
Above example only expresses the several embodiments of the utility model, its description is more specific and detailed, but simultaneously
Therefore the limitation to utility model patent scope cannot be interpreted as.It should be pointed out that the ordinary skill people for this area
For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality
With new protection domain.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
