Contactless tag reader system having electronic module magnetic field creating with coupling antenna connected transmitter/power amplifier and secondary antenna magnetic field placed reception delivering electrical signal.

摘要

The contactless tag reader system has a magnetic field created by an electronic module with the tag (3) placed in position. A coupling antenna is connected to a transmitter with a power amplifier providing a high frequency signal, and detecting the tag modulation. A secondary antenna (20) is placed in the magnetic field which delivers the electrical signal to the reception.
