discuss basic theory of near and far field antenna coupling in application to RFID and present some experimental measurements with emphasis on physical tag performance.
The electromagnetic field that surrounds an RFID antenna can be broken up into two segments – near-field and far-field. Typically, near-field is defined as the field around the antenna up to one wavelength (λ) away (approximately up to 35 centimeters).discuss basic theory of near and far field antenna coupling in application to RFID and present some experimental measurements with emphasis on physical tag performance. What is Near-Field & Far-Field? RFID readers use radio signals to transmit instructions & receive data from the tags. Whenever a tag enters the electromagnetic field of the reader, it transmits data to the reader using two methods, depending on the distance. This varying field is typically divided into two segments—the near field and the far field. A good knowledge of their differences goes a long way toward understanding radio-wave propagation.

The size of the tag is not the only difference between far-field and near-field RFID technology. This article takes a closer look at how parameters and antennas can be modified to optimize the reading performance of near-field tags.
Passive low-frequency (LF) and high-frequency (HF) RFID tags operate in the near field, while ultrahigh-frequency (UHF) tags typically operate in the far field. You can not read tags that operate at different frequencies using a single interrogator. The integrated HF-RFID and UHF-RFID tag antenna has been proposed for lossy dielectric and other materials in near-field communication and mitigates polarization loss in far-field communication. The HF-RFID tag antenna of square spiral structure with measured impedance of 5.81 + j236.31 Ω is conjugate-matched with NT3H2111 chip at 13.56 MHz .
Meanwhile the LF tag works in near field, where magnetic coupling is possible, so it can be powered from the field without using its own supply. Further the transmit antenna could be also sensing the receiver within near field, which for far field isn't possible at all. We discuss the foundation of a near field and far field relationship model that helps confirm the interdependency of various factors as it relates to RFID tag performance.
rfid near field
Near-field is primarily magnetic and inductive in nature, while the far-field has both electric and magnetic components. A far-field antenna uses radiative coupling to energize the RFID tag.
