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. High-Frequency (HF) / NFC Near Field Communication tags: These tags operate at a frequency of 13.56 MHz and have a read range of up to several feet. HF RFID tags are commonly used in applications such as retail inventory management and asset tracking.
RFID antennas are used in several applications, such as automatic identification and tracking systems, point-of-sale systems, and inventory management. RFID antennas use an electromagnetic field to exchange data with tags nearby. .A key aspect of any RFID antenna is whether it is a far-field or near-field antenna. The difference in the two is the way in which they communicate with an RFID tag. Near-field RFID antennas typically use magnetic or inductive coupling to communicate with the tag when it .
This article takes a closer look at how parameters and antennas can be modified to optimize the reading performance of near-field tags. You can roughly divide UHF RFID into two categories based on the mechanism, in which the energy is transmitted from the .RFID tags are made up of an integrated circuit (IC), an antenna and a substrate. The part of an RFID tag that encodes identifying information is called the RFID inlay. There are two main types of RFID tags: Active RFID. An active RFID tag has its own power source, often a . RFID tags should be mounted transverse to the radial direction from the reader antenna as much as possible, and never along the radial direction. Using more than one antenna certainly helps the situation as shown below.
Consider Antenna Types: Near-field antennas are suitable for short-read ranges, while full-field, long-read range antennas are ideal for applications requiring extended reach. Anticipate Future Needs: Select RFID tags that meet your current requirements and anticipate future needs. Near-Field Capabilities: If it has a small loop-shaped antenna in the middle, it usually has near-field capabilities. UHF Structure & Materials Most UHF tag antennas are designed with a dipole-type structure. 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.
