Abstract: Rotary position sensors are provided. In one example implementation, a rotary position sensor can include a first member and a second member, one of the first and second members having a transmit aerial and a receive aerial and the other of the first and second members having an intermediate coupling element. The receive aerial has at least one receive conductive winding arranged to form a first set of current loops and a second set of current loops. The intermediate coupling element comprises a conductive material arranged in a pattern. The pattern of the intermediate coupling element and the layout of the first and second set of current loops are mutually arranged such that any electromotive force induced in the first set of current loops by a background magnetic field is substantially balanced by an electromotive force induced in the second set of current loops by the background magnetic field.
