Abstract: The invention relates to a method for manufacturing an antenna for a radiofrequency transponder, said antenna including a spiral comprising turns which extend, at least in part, over an insulating substrate; the method is characterised in that it includes the step ac-cording to which at least one first portion of each turn is deposited on said substrate at a first plane level, at least one second portion of each turn being formed or kept at a distance from the first plane level of the substrate, the axis of the spiral being parallel to the plane of the substrate. The invention also relates to a portable electronic object comprising, in a fixed or removable manner, the obtained antenna.

Abstract: Radiofrequency device with adjustable LC circuit comprising an electrical and/or electronic module. The invention relates to a communication device with a radio-frequency chip, said device comprising -an insulating support layer, -an electrical and/or electronic radiofrequency circuit on said insulating layer, said circuit comprising plates of an adjustable capacitor and/or an antenna spiral with adjustable inductance, -at least one element for adjusting a tuning frequency of the radiofrequency circuit. The device is distinguished in that said plates and/or spiral are included in an electrical and/or electronic chip card module, and in that said adjusting element connects an intermediate point of the spiral so as to decrease the available inductance and/or splits or links the plates so as to adjust the capacitance.

Abstract: The invention relates to a radiofrequency antenna circuit comprising at least one electrically conductive portion, in particular in the form of a track or wire, forming a first spiral having first turns and two end portions. The invention includes a second spiral extending substantially away from one of the end portions, along and between the turns of said first spiral. The invention also relates to a radiofrequency device comprising the antenna circuit.
