What is RFID and Application?
RFID (Radio Frequency IDentification) is used for
identifying physical objects using computer chips with
wireless communications capabilities. It is primarily used
in distribution and logistics for tracking product
information, distribution channels, and distribution logs.
RFID is attracting attention as a key technology of the
ubiquitous networking era. Now many users set RFID at farms
traceability system for animals feeding records or cargo
warehouse counting.
RFID Antenna Design
Antennas are used to transmit radio frequency energy from
location X to location Y. UHF RFID systems, the wavelength
in free space at 13.56 MHz is 22.12 meters. The standard
ground plane antenna has a length of one quarter of the
wavelength which is 5.53 meters. We are unlikely to come
close to such dimension. The probably antenna design
solution is using L and C passive components for resonance
circuits magnetic coupling. |

INVAX offers custom RFID antenna
design and development services to customers looking to
safely, efficiently, and successfully integrate complete
RFID solutions. INVAX engineers can design the antenna
technology around a given product form factor, physical
space, or application requirements. If you experience
specialized situations with read reliability, interference
issues, or form factor limitations, we can help you solve
these problems. INVAX will help you design a solution that
meets your placement, cost, power consumption, and read
differentiation (anti-collision) requirements.
