The upper surface of the metal bottom plate 12 is adjacent to the lower surface of the first dielectric layer 21, the upper surface of the first dielectric layer 21 is adjacent to the lower surface of the conducting metal strip line 12, the upper surface of the conducting metal strip line 12 is adjacent to the lower surface of the second dielectric layer 22, and the upper surface of the second dielectric layer 22 is adjacent to the lower surface of the oscillator antenna 11; the element antenna 11 and the conductive metal strip line 12 have a connection relationship.
In a preferred implementation manner, a stepped groove surface 4 is formed between the second medium layer 22 and the first medium layer 21, as shown in fig. 1, and the license plate electronic tag can be attached to the license plate through the groove surface 4. It will be appreciated that the groove surface 4 is covered with a layer of VHB glue, but other glues with strong adhesion are also possible.
In a preferred implementation, the conducting metal strip line 12 comprises a coupled antenna 121 located on the slot plane 4 and a microstrip line 122 embedded between the first medium layer 21 and the second medium layer 22. Further, the chip 3 is located on the coupling antenna 121. It will be appreciated that, because the VHB adhesive 5 on the groove surface 4 has a high adhesiveness, when the label is attached to the license plate and then detached, the chip 3 on the groove surface 4 is likely to be torn off together. Thereby damaging the label upon detachment.
It can be understood that the element antenna 11 and the coupling antenna 121 on the slot surface 4 are exposed on the surface of the license plate label, and in order to prevent the element antenna 11 and the coupling antenna 121 from rusting or being damaged, a layer of protective paint may be brushed on the surfaces of the element antenna 11 and the coupling antenna 121, but the surface of the chip 3 arranged on the coupling antenna 121 does not need to be brushed.
In a specific implementation, the element antenna 11 and the microstrip line 122 embedded in the dielectric layer 2 have a connection relationship, and the connection relationship between the element antenna and the microstrip line can be realized through the through hole 23 arranged on the dielectric layer 2.

In an alternative implementation, the lower surface of the tag, i.e., the metal bottom plate 13, may be provided with foam 6, which may fix the tag to a rear plate of a vehicle on which a license plate is mounted.
It should be noted that, when the tag is mounted on the rear plate of the license plate, in order to destroy the license plate as soon as it is removed, an anti-removal cut 41 may be formed on the groove surface 4, and when the tag is removed, the tag may be broken from the anti-removal cut 41, thereby damaging the tag. Preferably, the detachment prevention cuts 41 may be V-shaped cuts. It can be understood that the opened V-shaped cut groove is located on the dielectric layer 2, and does not affect the metal layer 1 (i.e. does not cut the metal layer). In a specific implementation, the opened V-shaped cutting groove is positioned on the groove surface 4 at the joint of the two steps. When the tamper evident slit 41 is formed in the label, the metal base plate 13, which is the lower surface of the label, is covered with the VHB paste 5.
