Abstract: It is disclosed an antenna array comprising a number of radiating elements and a supporting elongated flat printed circuit board (PCB) having a substrate and two opposite faces. Each radiating element is attached to the PCB; each radiating element is dipole-like and has a respective axis of symmetry; the axes of symmetry are aligned along a direction parallel to a longitudinal axis of the PCB and lie on a longitudinal plane parallel to a longitudinal center plane of the PCB and located between the opposite faces; the PCB comprises at least one conductive trace on one of the faces, the conductive trace acting as a ground plane; and for each radiating element, the PCB carries a respective feeding line to provide a feeding signal to the radiating element at a feed point located on the PCB and substantially belonging to the axis of symmetry.
