UHF RFID near-field tags are commonly referred to as „near-field“ or „micro“ UHF RFID tags. These tags are designed to operate in the near-field region of the UHF RFID spectrum, which typically ranges from about 865 MHz to 928 MHz. In the near-field region, the behaviour of electromagnetic waves is influenced by both magnetic and electric field components.
Near-field tags are characterized by their smaller dimensions compared to traditional UHF RFID tags designed for longer-range applications.
These tags are optimized for close-range communication with an RFID reader, typically within a range of a few centimetres to a few meters. The magnetic component of the electromagnetic wave plays a significant role in the near-field communication of these tags.
