Telecontrol for automobile comprising a device for suppressing magnetic coupling

摘要

The invention relates to a telecontrol (TEL) for the locking/unlocking and the starting of a motor vehicle comprising: —an electronic circuit (ELEC) comprising at least one pathway comprising an input pin (BE) and an output pin (BS), —a first radiofrequency antenna (ANT1) comprising a first loop disposed in the plane of the electronic circuit (ELEC), —a second radiofrequency antenna (ANT2) comprising a second loop disposed in the plane of the electronic circuit (ELEC), said second antenna (ANT2) comprising: —an input connector (CE) connected to the input pin (BE), —an output connector (CS) connected to the output pin (BS), —a tuning capacitor (C) linked to the electronic circuit (CIRC), for tuning the second antenna (ANT2) to a tuning frequency, characterized in that it comprises: —an inductive input component (COMP_E) placed between the input connector (CE) and the input pin (BE), and/or —an inductive output component (COMP_S) placed between the output connector (CS) and the output pin (BS).
