ABSTRACT:
A radio frequency (RF) sensor that measures RF current includes a substrate that has an inner perimeter that defines an aperture. A conductor extends through the aperture. Sensor pads are arranged on the aperture and are connected to form two sensor loops. The loops generate an electrical signal that represents RF current flow through the center conductor. Additionally, a plurality of circular conductive rings may be included in the RF sensor to generate a signal representing the voltage of the conductor.
