What is the difference between UHF and RFID?
The read range of passive UHF systems can be as long as 12 m, and UHF RFID has a faster data transfer rate than LF or HF. UHF RFID is the most sensitive to interference, but many UHF product manufacturers have found ways of designing tags, antennas, and readers to keep performance high even in difficult environments.
What is UHF RFID used for?
Passive UHF RFID systems are used in hundreds of different applications such as tool tracking , IT asset tracking, race timing, and laundry management. New applications for these tags are being discovered frequently due primarily to the tags’ long read range and low cost.
Does RFID use antenna?
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 radio waves are picked up by the antenna and send to the reader which decodes the waves as digital information.
What are RFID antennas?
RFID Antennas are necessary elements in an RFID system because they convert the RFID reader’s signal into RF waves that can be picked up by RFID tags. Without some type of RFID antenna, whether integrated or standalone, the RFID reader cannot properly send and receive signals to RFID tags.
Is RFID analog or digital?
RFID tags with sensors connected through the digital side do not have any modification in the analog front-end circuit or antenna. The sensing data is usually transmitted to the reader upon a specific requesting command according to the communication protocol.
How do I choose an RFID antenna?
When choosing an RFID antenna, be sure to select the frequency range that is right for your region. For example, an antenna tuned to the 865-868 MHz range and used in the United States would violate the regulations that govern the use of RFID equipment in the United States.
