A sensor system includes one or more rotor antennas on a shaft that moves within a stator bracket one or more of around an axis of the sensor system or along the axis of the sensor system, the one or more rotor antennas configured to communicate sensed data with one or more stator antennas on the stator bracket. Each rotor antenna has a rotor signal trace disposed on an outer rotor side of a dielectric substrate of the rotor antenna and a rotor return trace disposed on the outer rotor side of the dielectric substrate, wherein the rotor signal trace and the rotor return trace are not concentric with respect to each other. The one or more rotor antennas are configured to extend one or more of radially around an outer surface of the shaft of a sensor or along the outer surface of the shaft of the sensor.
