3. Antenna Tuner ID ISC.DAT
3.1. System Description of the Antenna Tuner
The ID ISC.DAT antenna tuner can communicate with a reader. This means no additional
connection besides the HF connection (coax cable) is required in order to control the multiplexer.
Power for the antenna tuner is also provided over this connection.
In addition to the tuning and calibrating capability for an RFID antenna, the antenna tuner also
makes it possible to disconnect the antenna tuned circuit.
