Patent ID: 8471562

Claim:
A multi-axial antenna system with co-located coils comprising: a toroidal shaped bobbin comprising an electrically non-conductive material; a first coil comprising opposite sections positioned around first opposite portions of the bobbin and through a central recess of the bobbin to generate a magnetic field in substantially a first direction when current flows through the first coil; a second coil comprising opposite sections positioned around second opposite portions of the bobbin and through the central recess to generate a magnetic field in substantially a second direction when current flows through the second coil, the second direction being orthogonal to the first direction; a third coil around the bobbin to generate a magnetic field in substantially a third direction when current flows through the third coil, the third direction being orthogonal to the first and second directions; and signal generating circuitry to vary signals to the first, second, and third coils to generate a magnetic field vector that is angled with respect to the first, second, and third directions, to simulate a tilted coil.
