Abstract (en)

[origin: WO8907347A1] A concentrator adapted to concentrate signals for reception by a receiver means, said concentrator comprising a conductive portion juxtaposed said receiver means, said concentrator being aligned so as to receive said signals and cause further signals to impinge on said receiver means, and thereby enhance reception of said signals by said receiver means. Also disclosed is a shield for substantially eliminating magnetic field radiation from within a predetermined area, the field being diverted from the area by means of conductive strip.
