The three main processes of RFID antenna manufacturing

　　In order to adapt to the different requirements of RFID performance parameters in different application scenarios, various RFID antenna manufacturing processes have emerged. At present, the most commonly used RFID antenna manufacturing processes mainly include coil winding method, etching method and printing method.

　　(1) Coil winding method

　　When using the coil winding method to make an RFID tag antenna, the tag coil must be wound on a winding tool and fixed. The antenna coil is required to have a large number of turns. The coil can be either a circular ring or a rectangular ring. . This method is generally used for RFID tags with a frequency range of 125 to 134KHz. The shortcomings of using this processing method to make antennas are obvious, which can be summarized as high cost, low production efficiency, and insufficient consistency of processed products.

　　(2) Etching method

　　The etching method usually uses copper or aluminum to make antennas. This method is similar in production process to the etching process of flexible printed circuit boards. The etching method can be used in mass production of electronic tags with 13.56MHz and UHF bandwidth. It has the advantages of fine circuit, low resistivity, good weather resistance, and stable signal. However, the shortcomings of this method are also obvious, such as cumbersome production procedures and low productivity.

　　(3) Printing method

　　The printed antenna is a circuit in which conductive ink is directly printed on an insulating substrate (or film) to form an antenna. The main printing method has expanded from only using screen printing to offset printing, flexographic printing, gravure printing and other production methods. The printing method is suitable for mass production of 13.56MHz and RFID UHF electronic tags. It is characterized by fast production speed, but due to the large resistance of the circuit formed by conductive ink, its application range is limited to a certain extent. Due to the advancement of printed antenna technology, the cost of RFID tags is effectively reduced, which promotes the popularization of RFID applications.
