Abstract
The device for sensing a RF field comprises a flux-receiving loop () including a circumferential path having a defined path width (d), the flux-receiving loop () having a portion () that transforms the magnetic flux flowing through the flux receiving loop () into a high magnetic field. The portion () comprises a constriction of the flux-receiving loop () that concentrates the current lines in the circumferential path to define a current-field transformer. At least one very low noise magnetic field transducer () is located at a very close distance from the constriction.
