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.
