RFID Antennas & Switches

How do RFID antennas work?

What are RFID antennas and how they work? RFID antenna is a wireless data interchange system, by using an electromagnetic field as media.  An RFID system always has two elements:

  • - The transponder antenna, which is located on the object to be identified.
  • - The interrogator or reader, which, depending upon design and the technology used, may be a read or write/read device.

RFID Antennas work by the reader sending out electromagnetic waves through an alternating current passing by the reader antenna. Tag antenna is tuned to receive these waves.

PREMO Group can supply both elements of an RFID System, and design them in order to achieve the maximum power transference.

RFID Antenna Applications.

What are the main applications of RFID Antennas? At present, some of the main uses of 125 kHz RFID antennas systems are:

  1. 1. Automotive TPMS (Tyre Pressure Monitoring System). Here, is required high sensitivity and high stability in a wide range of temperatures.
  2. 2. Automotive RKES (Remote Keyless Entry System). In these applications, the antenna required very high sensitivity and stability. And good mechanical performance in drop impact and its derivative effort effects.
  3. 3. Automobile immobilizers. Here is required the same features as RKES application transponders.
  4. 4. Logistics and remote access, where transponders data can also be changed at will, and security mechanisms (authentication) can be used to prevent unauthorized writing or reading of stored data.
  5. 5. Animal identification. Sensitivity and reduced dimensions are the most valuable characteristics in these applications.
  6. 6. New revolutionary uses such as IoT, robotics, wireless sensors, wearables, smart cities.
