ABSTRACT:
A receiving antenna for use in proximity to an antenna having a circular radiating magnetic field includes at least one antenna having a null spatial sensitivity pattern along at least one axis, oriented with the circular radiating antenna located in said null pattern. In a preferred embodiment, the antenna having spatial sensitivity is three orthogonally oriented loop antennas, arranged to be insensitive to signals from the circular radiating antenna and sensitive to TE and TM signals from a remote location.
