    摘要: The invention relates to a beamforming circuit for a phased-array antenna including a straight line of electronic oscillators with coupled radio frequencies (VC01 - VC05), wherein at least two oscillators (VC01, VC05) located at the ends of said line have a variable free-oscillation frequency, said circuit being characterised in that said oscillators are differential oscillators, each of said oscillators being suitable for generating a first so-called positive oscillating signal (Φ
    P1 ) and a second so-called negative oscillating signal (Φ
    Ν1 ) which have opposite phases. The invention relates to a phased-array antenna system including a beamforming circuit according to one of the preceding claims, as well as to a plurality of antenna elements (EA1 - EA5) arranged so as to form a phased array powered by said circuit.
