Description

Manufacturing method of UHF electronic tag antenna, electronic tag and antenna

This is a major field of revolutionary technology applications. At present, its bottleneck problem is How to mass-produce its key components - electronic tags at low cost.

Since the UHF frequency band electronic tag is in the microwave frequency band, the tag antenna used by it limits the size of the antenna from the principle of microwave transmission and cannot be made too small. Generally speaking, in order to ensure the transmission efficiency of the microwave, the antenna's The effective geometry needs to be comparable to its wavelength, typically half a wavelength. In the UHF frequency band, for example, the electronic tag near the frequency of 900MHZ has a wavelength of more than 30 cm and a half wavelength of more than 15 cm. Therefore, when packaging and producing electronic tags, the production equipment is also relatively large due to the large size of the antenna. Due to the large production equipment and super long working stroke, the production efficiency of the electronic label is greatly reduced. In addition, due to the large size of a single piece, only a small number of products can be produced each time the production unit is installed, and frequent replacement of the installation unit also greatly reduces the production efficiency. The production efficiency is reduced, which makes it difficult to realize low-cost mass electronic label production.
