Abstract
A portable receiver comprised of several antennas that are connected to a receiver unit for receiving a signal transmitted by an electromagnetic induction process. The antennas are made in the form of coils, that are carried by a support in such a way that the respective turns of the coils are oriented along different respective axes of an axis system associated with the support. The invention further includes a phase shifting means oriented between the antennas and the receiver unit. The phase shifting means is designed to produce a temporal phase shift corresponding to an angle of (n−1)&pgr;/n, at the frequency of the signal received between induced signals delivered by the antennas (n being the number of antennas).
