A hands-free opener for a power liftgate provides a proximity sensor that fits into an operating position behind the vehicle license plate or in the license plate area. A driven shield located behind the sensor shapes the electric field from the sensor to achieve directional detection extending outward from the front side of the sensor. A proximate ground plane at a preselected spacing from the back side of the ground plane reduces interference.
