Abstract (en)
[origin: EP0889444A2] The identification system is in the form of a receiver that has two coils (10,12) within a common plane (18). The coils both act as transmitters that handle the same signals and have axes (14,16) that produce field lines (24). The field strength in the near field of the coils is amplified. At a distance the field lines density is reduced and the transmission signals are attenuated in the distant field.
