Abstract
The present invention relates to an electronic tag (30, 40) comprising a contactless integrated circuit (10) and a main coil antenna (Ls) comprising at least two distinct non-coplanar and/or non-coaxial windings (Ls1-Ls4) arranged in series. Applications to the reading of a tag from any face of a three-dimensional object.
Claims12
Electronic tag (30, 40) comprising at least one contactless integrated circuit (10) and at least one main coil antenna (Ls), characterised in that the main coil antenna (Ls) comprises at least two non-coplanar and/or non-coaxial windings (Ls1-Ls4) arranged in series, the two windings, if they are coaxial, being a distance apart from each other which is at least equal to the diameter of one of the windings.
Three-dimensional object (40), characterized in that it comprises two non-coplanar and/or non-coaxial windings (Ls1-Ls4) arranged in series at least on two of its faces or in the vicinity of two of its faces, forming together a coil antenna (Ls) for electronic tag, the two windings, if they are coaxial, being a distance apart from each other which is at least equal to the diameter of one of the windings.
Three-dimensional object, characterized in that it comprises two non-coaxial windings (Ls1-Ls4) arranged in series at least on one of its faces, forming together a coil antenna (Ls) for electronic tag.
