Abstract (en)
The magnetic field antenna comprises a flat base (4) with a longitudinal edge (2), an electromagnetic coupling receiving antenna (14) placed on the base, and parallel and perpendicular coils that extend to the longitudinal edge. The longitudinal edge is intended to be parallel to a booklet binder, and is adjacent to a hinge booklet. The parallel coils have close-together inter-coil spacing (ES) of 0.1-0.5 mm with respect to an inter-coil spacing (EL) (0.5-2 mm) of the perpendicular coils, and are localized in an area (7) located at a support medium that is perpendicular to the edge.

The longitudinal edge is intended to be parallel to a booklet binder, and is adjacent to a hinge booklet. The parallel coils have close-together inter-coil spacing (ES) of 0.1-0.5 mm with respect to an inter-coil spacing (EL) (0.5-2 mm) of the perpendicular coils, and are localized in an area (7) located at a support medium that is perpendicular to the edge. The antenna is made of wire having a diameter of 50-150 mu m. The parallel coils of the area are located at a distance (B) of the longitudinal edge that is higher than a distance (A) for portions of parallel coils located apart from the area. An independent claim is included for a portable electronic object.
Abstract (fr)
L'invention concerne une antenne pour transpondeur radiofréquence comportant un support plan (4) avec un bord longitudinal (2), une antenne de réception (14) par couplage électromagnétique sur le support, ledit bord étant destiné à être parallèle à une reliure de livret, ladite antenne comportant des spires parallèles et perpendiculaires s'étendant respectivement parallèlement et perpendiculairement au bord longitudinal (2) ; Le transpondeur se distingue en ce que lesdites spires parallèles présentent un espacement inter-spires rapproché (ES) par rapport à l'espacement inter-spires (EL) des spires perpendiculaires. L'invention concerne également un objet portable électronique comprenant ledit transpondeur
