Abstract
A signal transmission system (STS) comprises a transmitter (T) with a first LC circuit comprising a first coil (C) intended to be fed with signals having a chosen carrier frequency, and a receiver (R) with a second LC circuit comprising a second coil (C) and coupled to a circuit front-end (FE). The first coil (C) is arranged to transfer energy to the second coil (C) by magnetic induction in a near-field propagation mode. The first LC circuit (C) has an increased quality factor and is tuned to a first frequency which is shifted in a first direction from the carrier frequency by a first value, and the second LC circuit (C) has an increased quality factor and is tuned to a second frequency which is shifted in a second direction, opposite to the first one, from the carrier frequency by a second value.
