Abstract
The disclosure relates to a ferrite antenna comprising at least one main contour, comprising at least one first winding referred to as main winding, at least one first ferromagnetic rod referred to as main ferromagnetic rod and a tuning system, each main winding being wound around a main ferromagnetic rod and connected to the tuning system comprising a capacitor connected in parallel with the main winding. The ferrite antenna further comprises a non-resonant secondary contour, comprising a secondary winding separated electrically from each main winding and a secondary ferromagnetic rod around which the secondary winding is wound, and each main ferromagnetic rod and the secondary ferromagnetic rod are arranged parallel to one another so as to make it possible for a magnetic coupling of each main winding with the secondary winding.
