Functional Description

The transponder-antenna is used in identification systems with positioning. When a transponder enters reception range 2 the antenna outputs the transponder‘s code. When the transponder crosses the antenna center (see functional principle) the positioning pulse is generated. This allows the detection of fixed positions.

Connection example
Connection Example Transponder-Antenna

As soon as a transponder is within the reading area the antenna wirelessly supplies it with inductive energy. The transponder uses that energy to cyclically transmit its code at half the antenna‘s operating frequency. Otherwise the transponder is passive and doesn‘t need any power supply or battery. There may always be at most one transponder within the reading area of the antenna.

Functional principle
Functional principle transponder positioning

The antenna can program new codes into compatible read/write (R/W) transponders.

Possible Applications in Automation Systems, e.g.

  • Storage
  • Material Handling
  • Identification of Containers
  • Positioning of trackguided Vehicles
  • Assembly Lines
