Due to the continuous progress of RFID technology, the production and development of RFID electronic tags are becoming more and more mature, and have been widely used in various industries. However, due to the limitations of its own appearance, shape and physical size, traditional RFID electronic tag cards cannot be applied to all occasions, such as commodity anti-counterfeiting, pet identification, special occasions, etc., and must be used in a relatively small size Small RFID electronic tags, especially micro RFID electronic tags.

中国专利号为ZL200620062913.7，公开号为2938228的“一种小型电子标签”的实用新型专利公开了一种电子标签，该电子标签采用的技术方案是：将集成电路裸片叠在贴片电容上，贴片电容的两端通过连接线与集成电路裸片的引脚连接，在贴片电容上粘结有绝缘保护胶，绝缘保护胶将整个集成电路裸片包于其内，电路裸片包于其内，使贴片电容和集成电路裸片构成一个整体，天线线圈的两个端头连接至贴片电容的两端，该电子标签将全部构件封装在一个内径不到两毫米的玻璃管内，克服了普通型RFID电子标签体积偏大，无法在一些对其体积要求较严的场所使用的缺陷，作为RFID家族中的一个分支，这种微型电子标签，与其它品种的非接触智能卡产品在各个行业领域的大量推广，起到了非常好的拓展和互补性作用，但由于该电子标签中存在一贴片电容，体积还不够小，特别是该电子标签未使用导磁率高的微型磁棒，其感应灵敏度不高，识别距离很有限。The Chinese patent number is ZL200620062913.7, and the utility model patent of "a small electronic label" with the publication number 2938228 discloses an electronic label. On the surface, the two ends of the chip capacitor are connected to the pins of the IC bare chip through the connecting wire, and the insulating protective glue is bonded on the chip capacitor, and the insulating protective glue wraps the entire integrated circuit bare chip in it, and the circuit bare chip Wrapped in it, the chip capacitor and the integrated circuit die form a whole. The two ends of the antenna coil are connected to the two ends of the chip capacitor. The electronic tag encapsulates all components in a glass with an inner diameter of less than two millimeters. In the tube, it overcomes the defect that ordinary RFID electronic tags are too large in size and cannot be used in some places with strict volume requirements. As a branch of the RFID family, this miniature electronic tag is different from other types of non-contact smart card products. A large number of promotions in various industries have played a very good role in expansion and complementarity. However, due to the existence of a chip capacitor in the electronic tag, the volume is not small enough, especially the electronic tag does not use a micro-magnetic rod with high magnetic permeability. , its sensing sensitivity is not high, and the recognition distance is very limited.
