An antenna slot 101 is provided on the substrate layer 1, and the antenna layer 2 is disposed in the antenna slot 101, with the surface of the antenna layer 2 flush with the surface of the substrate layer 1. A chip 10 is disposed on the antenna layer 2, and a temperature sensor is integrated inside the chip 10. A positioning part 102 is provided in the antenna slot 101, and a corresponding element is provided on the antenna layer 2 to align with the positioning part 102. The positioning part 102 can be paired and inserted into the positioning hole 201. The side of the substrate layer 1 with the antenna groove 101 is covered with a sealing protective layer 5. The sealing protective layer 5 and the substrate layer 1 are bonded together with waterproof sealant 6. The end of the substrate layer 1 away from the face material layer 3 is provided with a base material layer 4. The edge of the base material layer 4 is sewn to the edge of the face material layer 3, so that a receiving cavity is formed between the base material layer 4 and the face material layer 3. The substrate layer 1 is placed in the receiving cavity. A buffer and pressure-resistant layer 7 is provided in the receiving cavity to wrap the substrate layer 1 and the sealing protective layer 5.
[0020] By providing the antenna slot 101, precise positioning and support are provided for the installation of the antenna layer 2. The antenna layer 2 can be easily embedded into the antenna slot 101 of the substrate layer 1, and the surface of the antenna layer 2 is flush with the surface of the substrate layer 1, ensuring the flatness and aesthetics of the electronic tag and greatly simplifying the installation process. Positioning holes 201 and positioning parts 102 are provided; their paired insertion further ensures the stability and accuracy of the antenna layer 2 on the substrate layer 1, avoiding misalignment and offset during installation, thereby improving installation efficiency and quality. The sealing protective layer 5 is bonded to the substrate layer 1 with waterproof sealant 6, forming a solid waterproof barrier that effectively prevents moisture and humidity from corroding the internal components of the electronic tag, improving its waterproof performance and extending its service life. The buffer pressure-resistant layer 7 in the receiving cavity provides all-round protection for the electronic tag.
