ABSTRACT:
Multiple monopole antennas or loop antennas for generating electromagnetic fields whose phases become opposite to the phase of an electromagnetic field that the conventional single monopole antenna or loop antenna generates are located in proximity to the conventional single monopole antenna or loop antenna such that the components of the electromagnetic field in directions other than a probe-desired direction will be cancelled out.
