Description
Technical field
The utility model relates to a kind of electronic tag, particularly a kind of bifrequency electronic tag.
Background technology
At present, known RFID is single-die and single antenna composition, by falling encapsulation technology by die package antenna contacts, become finished product after some glue is fixing, after label enters magnetic field, receive the radiofrequency signal that plug-in reader sends, the energy obtained by means of induction current sends out storage product information in the chips, or initiatively send the signal of a certain frequency, plug-in reader reads information and after decoding, delivers to CIS and carry out relevant data process.The reading frequency that single electronic tag is corresponding single, if want the frequency adjusting a chip in this case, a few money electronic antenna of over-bought carry out the frequency of falling packaging and testing, and very elapsed time and material, fund input is large.Cost is high.
Utility model content
For the weak point mentioned in the problems referred to above, the utility model provides a kind of bifrequency electronic tag, and this label not only volume is little, and can select two kinds of frequencies.
To achieve these goals, the utility model is realized by following technical scheme.
A kind of bifrequency electronic tag, comprise a substrate, described substrate is provided with antenna, and described antenna is closing coil, described substrate is also provided with the first chip and the second chip, wherein,
The first interface of described first chip, the first bridge, first axle, the second bridge, described antenna, the 3rd bridge, the second axis are connected successively with the first interface of the 4th bridge, second interface of described 4th bridge is connected with the second interface of described first chip, form the first closed circuit
The first interface of described second chip, described 4th bridge, the second axis, described 3rd bridge, described antenna are connected successively, and the port of described antenna is connected with the second interface of described second chip, forms the second closed circuit.
Described antenna is adhered on the substrate by etch printing by good conductor layer.
The frequency range of described first closed circuit controls at 15.2MHZ-15.6MHZ.
The frequency range of described second closed circuit controls at 13.2MHZ-13.5MHZ.
Described first chip and described second chip are high frequency chip.
Described antenna is the square structure of four limit symmetries.
The beneficial effects of the utility model are:
The utility model provides a kind of bifrequency electronic tag, utilize the length of etching antenna circuit to change the reading frequency of label, the frequency range of high frequency closed circuit controls at 15.2MHZ-15.6MHZ, the frequency range of low frequency closed circuit controls at 13.2MHZ-13.5MHZ, thus makes label reach double frequency selection.Bifrequency electronic tag is easy to use, reduces costs simultaneously.
