Abstract
A device for receiving and demodulating an amplitude-modulated RF signal, comprising: a first antenna; a first amplifier coupled to the first antenna; a receiving module including: a) a second antenna; b) a second amplifier coupled to the second antenna; c) a phase-shifter coupled to the second amplifier and applying a phase-shift Φ; d) a mixer comprising inputs coupled to the phase-shifter and to the first amplifier, and outputting a product of signals received at the input, and wherein the value of the phase-shift Φ is such that the device performs a demodulation of the RF signal when a wavefront of the RF signal forms, with an axis of alignment of the antennas, an angle α having a particular value a which depends on the phase-shift Φ and on a distance between the antennas.
