RFID antenna

What is the RFID antenna?

RFID antennas are an essential element in an RFID system because they convert the RFID reader's signal into RF waves that can be received by the RFID tag. Without some type of RFID antenna (whether integrated or standalone), an RFID reader cannot properly send and receive signals to and from RFID tags.

What is the best antenna for RFID?

Antennas with circular polarization are preferred when RFID tags change orientation or position relative to the antenna.

How to design RFID antenna?

In summary, when selecting the appropriate type of RFID antenna, consider the application requirements,read range, directionality, available space, the proximity of the tag to the antenna, and the frequency of the RFID system

What are the applications of RFID antenna?

RFID antennas are used to read RFID tags in warehouses, production lines, stores, medical centres, sports events, etc.

How to choose RFID antenna?

1. Dimension of the antenna.

2. Read range of the antenna (near-field/ far-field)

3. Environmental Protection (IP rating)

4. Wide or narrow beam pattern.

5. Antenna connectors / Cable length.

6. Reader with integrated antenna or an external antenna.

7. Frequency / region.
