Background

Radio Frequency Identification (RFID) technology is an innovative application of modern scientific technology in all aspects of society. The RFID technology has been widely used in retail industry, logistics industry, manufacturing industry, and other fields. With the deep collaboration of three parties, namely, aircraft manufacturers, part suppliers and airlines, RFID technology has gradually penetrated all links of the supply chain system in the aviation field. The basic working principle of the RFID device is that a reader-writer sends a radio frequency signal to an electronic tag, the electronic tag induces current inside the electronic tag, and then stored information is provided for a reader. Data are stored in electronic data carriers (transponders), the exchange of which is done by means of magnetic or electromagnetic fields, using radio and radar technology.

RFID is a simple wireless system consisting of one interrogator (or reader) and many transponders (or tags). The RF technology utilizes a wireless radio frequency mode to carry out non-contact bidirectional data transmission between the reader and the radio frequency card so as to achieve the purposes of target identification and data exchange. The most basic RF system consists of three parts: 1) tag (Tag, i.e. radio frequency card): the tag comprises a coupling element and a chip, and the tag comprises a built-in antenna and is used for communicating with a radio frequency antenna. 2) And a reader: a device that reads (or can write in a read-write card) tag information; 3) and a radio frequency antenna: radio frequency signals are communicated between the tag and the reader.

(1) a larger space is required to be added on the printed circuit board for laying the RFID label induction antenna, which is difficult to meet the requirement of a small or special-shaped printed circuit board;

(2) the RFID label induction antenna is designed with professional electrical parameter requirements, and the shape of the induction antenna is related to the attached medium environment, so that a plurality of working difficulties are increased for printed circuit board designers;
