Zusammenfassung:A passive, non-multiplexed, two-axis antenna for sensing time-varying magnetic fields of a particular carrier frequency at a second point in space as produced by a electromagnetic field generator located at a first point in space. The antenna has a particular sensitive plane and produces a single output signal having amplitude proportionally related to the magnitude of the incident magnetic field's vector projection onto the antenna's sensitive plane. If the phase of the magnetic field is known, then the antenna's signal is processed to obtain the incident magnetic field's vector components. The antenna enables the realization of two- or three-axis magnetic field receivers with reduced signal processing complexity, cost and power requirements.
