ABSTRACT:
A device for generating an electromagnetic field by a first oscillating circuit excited by a high-frequency signal, including, at a distance from the first oscillating circuit, a second passive, unloaded and coreless oscillating circuit, forming an element for concentrating the magnetic flux intended to be intercepted by a transponder by a third oscillating circuit.
