Basic Knowladge for RFID Antennas
What is RFID Antennas ?
RFID Antennas are responsible for emitting and receiving waves that allow us to detect RFID chips. When an RFID chip crosses the antenna field, it is activated and emits a signal. The antennas create different wave fields and cover different distances.
What is the difference between RFID readers vs 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.
How do I choose an RFID antenna?
Read range and size: smaller antennas within the same frequency will have shorter read range and vice versa. Profile width – if you are short on space or for esthetic reasons, you may need to look for low profile antennas that have a side connector or a side pigtail. Gain – gain affects read range and beamwidth.
Where is UHF RFID used?
Active UHF RFID applications are frequently used in industries like oil and gas, transportation, and vehicle tracking. Because active tags beacon, they are easier to read while moving and are ideal for tracking cargo containers and vehicles.
