Patent number: 11295193Abstract: A radiofrequency transponder comprises a radiating antenna consisting of a single-strand helical spring having an axis, a median plane, a pitch and a diameter for a given wire diameter, and an electronic portion located inside the radiating antenna. The electronic portion comprises an electronic chip electrically connected to a primary antenna that is electromagnetically coupled to the radiating antenna. The primary antenna has an axis parallel to the axis of the radiating antenna and a median plane superposed with the median plane of the radiating antenna. The primary antenna is circumscribed by a cylinder the diameter of which is larger than one third of the inside diameter of the radiating antenna.Type: GrantFiled: March 27, 2019Date of Patent: April 5, 2022Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Julien Destraves, Thomas Caro, Jean-Mathieu Clergeat, Laurent Couturier, Guillaume Portier
