Problems solved by technology

[0003] The existing tag antenna production methods usually use PET film as the base material for aluminum etching antennas. PET film is a polyethylene terephthalate polymer material that is not easy to degrade, and it is easy to pollute the environment after application; in addition, the Such antennas basically use chemical etching, which also causes pollution and damage to the environment.
[0004] In the existing tag antenna production technology, except that the printing method can be used to produce antennas on disposable materials such as paper, other production methods cannot achieve the purpose of disposable antenna production
[0005] The wire winding method is to wind a certain number of turns with a certain fineness metal wire (usually copper wire) to complete the production of the antenna. In this way, there is no fixed antenna attached to the base material, the production cost is relatively high, and the production efficiency is low; Etching and electroplating methods cannot make antennas on disposable materials. In addition, these two production methods are relatively expensive and cause environmental pollution.
The printing method mainly relies on conductive ink. The printing thickness and concentration of conductive ink are not easy to control, which may easily cause unstable performance of the label antenna. At the same time, the printed antenna is easily damaged, resulting in failure of reading and writing, and poor anti-friction performance. The antenna printed with conductive ink is of poor quality. The stability is not good, especially in flexible labels, the antenna is easy to damage, leading to label failure, and the cost is relatively high; the steps of electroplating the antenna are complicated, the production cycle is long, and the waste liquid washing liquid is easy to cause environmental pollution, which is difficult to promote

Description

technical field [0001] The invention belongs to the technical field of antenna production, and in particular relates to a production method of an RFID paper-based aluminum antenna. Background technique [0002] The English full name of RFID is Radio Frequency Identification. Simply speaking, RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals. The entire identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and single very specific objects, and can identify multiple tags at the same time. Because it uses radio frequency, it can read data through external materials, and can identify multiple objects at the same time, so it is more convenient and quicker. In addition to these, the biggest feature is that the amount of stored information is...
