Abstract

The invention discloses an RFID printed antenna and a preparation method thereof, The RFID printed antenna comprises a substrate, a protective plate, a printed antenna and a polymer film layer. The printed antenna is a printed conductive antenna printed between the substrate and the protective plate by using conductive ink. A matching positioning protrusion and a positioning groove are arranged between the protective plate and the substrate. The polymer film layer is sealed and coated on the exterior of the substrate and the protective plate. The invention has unique structural hierarchy design, good waterproof, folding-proof, fire-proof and electric conductivity performance, wide application range, and the preparation method is easy to realize, which is conducive to reducing the production cost of enterprises and popularizing the RFID electronic tag technology.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to an RFID printing antenna with unique structure, stable performance and long service life and a preparation method thereof. technical background [0002] RFID, called radio frequency identification, is a communication technology, commonly known as electronic tags, which can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets. It is a non-contact The automatic identification technology automatically identifies the target object and obtains relevant data through radio frequency signals. The current RFID tag system is mainly composed of three parts, namely tags, readers and antennas. Due to the high cost and slow speed of the copper wire winding process of the traditional manufacturing technology, and the disadvantages of low precision, env...
