What type of antenna is used in RFID?
Linear antennas generally propagate a narrow but longer tag read field. Circular antennas propagate a much wider but shorter tag read field. Circular antennas are more commonly used for most applications whereas linear antennas are used to read tags in specific targeted areas.
How do you create an RFID?
An RFID system consists of three parts: a scanning antenna, an RFID tag which includes all of the information about a product, and a reader which decodes and interprets data on a tag. These three pieces fit into a process where: Data is first stored in an RFID tag in either a read-only or read-write format.
How many types of RFID tags are there?
RFID tags can be grouped into three categories based on the range of frequencies they use to communicate data: low frequency (LF), high frequency (HF) and ultra-high frequency (UHF).
What kind of RFID reader can read 134.2 kHz?
Companion animal tags in the US are commonly 125 kHz. Some tags are non-ISO/proprietary and can only be read with the manufacturer’s reader. Many 125 kHz readers can be modified to read 134.2 kHz by replacing the crystal.
How to determine the read range of a RFID tag?
With a linear antenna, if the tag is oriented from 9 – 3 and you aren’t picking it up, try rotating it to 6 – 12. This is a quick test which mainly applies to tags with a single dipole (e.g. the Alien Squiggle ).
This low frequency, fixed reader is ISO 11784/5 compliant and thus able to read all FDXB and HDX RFID tags. The reader is designed with several advanced functions and tailored specially for continuous operation in harsh environments found in feeding stations, animal scales or sorting gates.
Is the 212002 RFID reader IP54 protected?
The 212002 fixed RFID reader has a durable case with an IP54 protection rating, and its integrated LEDs and function key provide for ease of operation. The reader also supplies a clock synchronization enabling applications where several readers or antennae are used in close proximity.
