With the advent of the mobile Internet era with 5G technology as the benchmark, the Internet of Everything and the perception of everything are gradually becoming a reality. RFID is an important support technology for the Internet of Things to perceive the outside world. According to the different working frequencies, RFID tags can be divided into low frequency (LF), Different types of high frequency (HF), ultra high frequency (UHF) and microwave. The working principles of RFID in different frequency bands are different. RFID in LF and HF frequency bands generally use the principle of electromagnetic coupling, while RFID in UHF and microwave frequency bands generally use the principle of electromagnetic emission. To use it correctly, you must first select the appropriate frequency. Each frequency has its characteristics and is used in different fields.
