Position sensing apparatus and method

An inductive position sensor configured to detect relative position between a first member and a second member, the inductive position sensor comprising:

• a transmit aerial configured to be disposed on the first member, the transmit aerial having at least one transmit winding;
• a receive aerial configured to be disposed on the first member, the receive aerial comprising one or more receive windings;
• a coupling element operable to be disposed on the second member;
• processing circuitry configured to provide one or more signals indicative of the position of the first member relative to the second member based on current induced in the one or more receive windings resulting from an oscillating signal provided to the transmit winding;
• a first electrostatic shield, the first electrostatic shield comprising a first plurality of conductive traces arranged so that no current loops are formed in the first electrostatic shield;
• and
• a second electrostatic shield, the second electrostatic shield comprising a second plurality of conductive traces arranged so that no current loops are formed in the second electrostatic shield,
• wherein the at least one transmit winding and the one or more receive windings are disposed between the first electrostatic shield and the second electrostatic shield, and
• wherein at least one of the first plurality of conductive traces or the second plurality of conductive traces comprises:
• a first conductive trace extending from a first end portion to a second end portion, the first conductive trace extending along a linear axis from the first end portion to the second end portion;
• and
• multiple second conductive traces extending from the first conductive trace, the multiple second conductive traces being spaced apart along the linear axis and extending from the first conductive trace in a direction that is perpendicular to the linear axis.
