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.
Antenna Type: Circular polarization antennas work best in environments where the orientation of the tag varies. Linear polarization antennas are used when the orientation of the tags is known and controlled and is always the same. NF (Near Field) antennas are used to read RFID tags within a few centimeters.
