Motor vehicle door handle, has capacitors whose capacitance is selected such that influence of interfering signal at supply line in capacitance of sensor is reduced without interfering transmission of high frequency signals through coil

摘要

The handle has a control and evaluation circuit (5) coupled with a sensor electrode (3) of a capacitive proximity sensor. Capacitors (11, 12) are engaged between supply lines (10) of an antenna coil and an earth line and/or a voltage supply line. The capacitance of the capacitors is selected such that the influence of interfering signal at the coil supply line in the capacitance of the sensor, which is detected by the circuit, is reduced without interfering the transmission of the long wave high frequency signals through an antenna coil.
