Questions with RFID Antennas

  • Ask: What is a RFID antenna?

    Answer: What is an RFID Antenna? 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.

  • Ask: Which type of antenna is used in RFID tag?

    Answer: Coupling Technique: Backscatter coupling \u2013 reader's antenna generates RF energy to activate the RFID tag, which modulates the information and reflects the remaining energy back to the reader antenna.

  • Ask: How can I boost my RFID signal?

    Answer: If you need to read tags up close, use very low gain proximity antennas. The details: Simply put, a higher gain antenna increases the power received from the reader. If you want to make sure your antennas have a longer \u201creach,\u201d then you need high gain antennas (e.g. 9 dBi, or higher).

  • Ask: How far can RFID transmit?

    Answer: Ultra High Frequency (UHF) Passive RFID Tags. Minimum read distance of over 1 meter or 3 feet. Gen2 tags can have a read range of over 16 meters or 52 feet when using the full 4 Watt EIRP legally allowed on the readers by FCC and other global regulators (For your local power regulations see our RFID Education page).
