Abstract:
A portable receiver comprising several antennas (3, 4) which are connected to a receiver unit (5) for receiving a signal transmitted by electromagnetic induction, said antennas being made in the form of coils (L1, L2) which are carried by a support (2) in such a way that the respective turns of said coils are oriented along different respective axes (9, 11) of a reference axis system associated with said support (2), as well as phase-shifting means (15) placed between said antennas (3, 4) and said receiver unit (5), wherein said phase-shifting means (15) are designed to produce, between the induced signals delivered by said antennas (3, 4) respectively, a temporal phase shift corresponding to an angle of (nâˆ’1)&pgr;/n at the frequency of the signal to be received, n being the number of antennas.
