Abstract
A coupling antenna which includes a plurality of turns in series located on a planar support ( ) formed by an insulating dielectric substrate. The antenna includes one or several sets of at least one turn ( ) located on the planar support, mounted in series, at least one of the sets consisting of at least two spires ( ) in series superposed along an axis perpendicular to the plane of the support and separated by an insulating strip ( ) of dielectric ink, thereby resulting in a high inductance value. The invention also concerns the method for making such an antenna and the use of the antenna in a contactless smart card.
