ABSTRACT:
An antenna system for collecting electric waves for the reception of magnetic induction signals emitted by an active implantable medical device. The system includes an antenna that comprises a reception coil (10) and a compensation coil (20), each of which preferably includes at least one series of turns (12, 22) wound around respective mandrels (16, 26) made out of a nonmagnetic material. The mandrels are positioned side by side with their respective axes (18, 28) spaced apart and parallel, and with their cross sections areas not superimposed. The cross section of the mandrel (26) of the compensation coil (20) is less than that of the mandrel (16) of the reception coil (10). The series of turns (22) of the compensation coil (20) can be split in a plurality of groups of turns (24) wound on the same mandrel (26), with an axial spacing and connected in series, preferably with the sections of winding and/or different numbers of turns being different. The series of turns (22) also can be distributed on separate mandrels.
