Abstract:
A method for determining information on a position of an object, the object emitting a magnetic field in response to an exciting electromagnetic field comprises monitoring (100) a receive signal of at least one loop antenna, the receive signal having a contribution caused by the emitted magnetic field; determining a first quadrature component (102) of the receive signal; and determining the information on the position of the object (104) based on the first quadrature component.
