Abstract: An angular position sensor comprising two planar excitation coils forming a substantially circular interior area and two planar sensing coils positioned within a minor sector of the substantially circular interior area. Each of the two planar sensing coils comprises a clockwise winding portion and a counter-clockwise winding portion. The angular position sensor further comprises a substantially circular rotatable inductive coupling element positioned in overlying relation to the two planar sensing coils and separated from the two planar sensing coils by an airgap, wherein the substantially circular rotatable inductive coupling element comprises three, substantially evenly space, sector apertures.
