Secondly, the basic workflow of the electronic tag is introduced as follows:

1. the electronic tag reader transmits the radio carrier signal to the outside through the transmitting antenna.

2. When the electronic tag enters the working area of the transmitting antenna, the electronic tag is activated and transmits the code of the self information out through the antenna.

3. And the antenna of the electronic tag receives the carrier signal sent by the electronic tag and transmits the carrier signal to the electronic tag reader-writer through the regulator of the antenna. The reader demodulates and decodes the received signal and sends the demodulated signal to the background computer control system.

4. The computer control system judges the legality of the electronic tag according to the logic operation, performs corresponding processing and control aiming at different settings, and sends out instruction signals to control the action of the execution mechanism.

As a novel anti-tearing and anti-breaking radio frequency electronic tag, a tag IC chip is arranged in the radio frequency electronic tag, a unique identification code is stored in the IC chip, and a coupling antenna is connected with the IC chip in the radio frequency electronic tag. When the reader reads the electronic tag, the reader sends electromagnetic waves to the electronic tag, and the electromagnetic waves also contain a command for requiring the electronic tag to send back the stored codes. The coil of the antenna in the electronic tag converts electromagnetic waves into voltage for the IC chip to work, and after the IC chip receives the command, the code is sent to the reader through the antenna coil.

The chip of the radio frequency electronic tag with the flat strip structure is arranged in the middle, the antennas are arranged at two ends, and the antennas at the left end and the right end are respectively connected with the chip in the middle through the connecting wires at the left side and the right side. Because the connecting wire is made of a flexible material, the rf electronic tag of the present invention can be bent according to the structure of the target object (the bending shape of the rf electronic tag is shown in fig. 2).

The coupling antenna 1 and the connecting wire 3 can be made of the same material and be integrated, so that the connecting wire 3 has the functions of both the wire and the antenna.

The protective layer may also be made of other materials that do not affect the receiving function of the antenna. The bottom 7 mainly serves to form a space for accommodating the chip 2 of the electronic tag 100 with the connection layer 5, and the bottom 7 may be a layered component or any part of the target article 200. After the electronic tag 100 is mounted, the electronic tag 100 and the target article 200 are embedded into a non-detachable integral structure due to the adhesive effect of the double-sided adhesive tape sealing material 4, and once the connecting layer 5 and the target article 200 are separated, the electronic tag is damaged and cannot be used, so that the electronic tag with the structure cannot be moved to other articles to be reused, and the anti-counterfeiting effect is very high.

Of course, besides the double-sided tape sealing material 4 of the electronic tag 100 itself, the multi-layer member of the target object may be reinforced by other connecting and fixing methods, for example, the connecting layer 5 and the bottom 7 may be connected and fixed by other general technical means such as adhesion, screw connection, and the like.

The passage direction of the through groove 8 is perpendicular to the upper and lower surfaces of the connection layer. The length of the electronic tag 100 may be adjusted to fit the layered structure of the target article 200 according to the thickness of the connection layer 5 of the target article 200 or the distance between the two through-grooves 8.

As various alternatives, as shown in fig. 6 to 10, the through slot 8 has an inclination angle with respect to the upper and lower surfaces of the connection layer 5 as viewed in the side view direction, and may be inclined at an acute angle, so that the electronic tag as a whole has a dovetail shape, and the inclination angle is 30 to 60 degrees, and preferably 45 degrees.

Or may be inclined at an obtuse angle, so that the electronic tag 100 is overall trapezoidal, and the inclination angle is 120 degrees and 150 degrees, preferably 135 degrees.
