The invention concerns a network antenna with reflector(s) (AR) comprising i ) a network (RS) of at least two sources (S1-S5), one of which a central sourc e (S1), arranged and positioned so as to transmit and/or receive beams (F1-F5) in selected directions; ii) beam-forming means for controlling the amplitude and the phase of each of the sources based on amplitude/phase laws applied upon their access and for providing an appropriate amplifying level, so that each source (S1-S5) should transmit a selected radiated pattern (forming a beam and including a main lobe) designed to cover a selected zone (Z1-Z5), a nd iii) at least one reflector (RC) provided with a surface (SU) capable of reflecting the beams delivered by the sources and/or addressed thereto and configured in three dimensions so as to reflect the beam delivered by each source (S1-S5) by spreading its energy so that it covers the selected associated zone, and that the main lobe of the radiated pattern associated with the central source (S1) should define a primary coverage (CP) including integrally each active coverage zone (ZC1, ZC2) of the antenna, of selected shape and dimensions, and that the main lobe of the radiated pattern associated with each non-central source (S2-S5) should overlap at least part ly the primary coverage (CP).
