[0018] The embodiments of the utility model will be described below through specific examples, and the person skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. The utility model can also be implemented or applied through other different embodiments, and each detail in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the utility model. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0019] It should be noted that the drawings provided in the following examples only illustrate the basic concept of the utility model in a schematic manner, and only the components related to the utility model are shown in the drawings, not the number, shape and size of the components during actual implementation. The shape, number and proportion of each component during actual implementation can be changed arbitrarily, and the component layout pattern can also be more complex.

[0020] All directional indications (such as up, down, left, right, front, back, transverse, longitudinal, etc.) in the embodiments of the utility model are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture, and if the specific posture changes, the directional indications also change accordingly.

[0021] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0022] The utility model provides a RFID electronic tag for tire, including the mutual connection of carrier board 1 and antenna 2, it implants in tire inside, as the exclusive identity mark of single tire.
