Abstract: A capacitive angular position sensor, including a stationary disk and a rotary disk, the disks disposed parallel to each other and each having, on one of its faces, a patterned conductive layer, wherein the conductive layer on the stationary disk includes—a plurality of first electrodes, each capacitively coupled to at least a portion of the conductive layer on the rotary disk, the capacitive coupling being variable with the angular position, a second electrode, formed as a ring and capacitively coupled with at least a portion of the conductive layer on the rotary disk and a third electrode, formed as a ring and disposed so as to have capacitive coupling with the conductive layer on the rotary disk, the capacitive coupling being significantly lower than the capacitive coupling between the second electrode and the conductive layer on the rotary disk.
