The present radiator pertains to a planar array antenna for sending or receiving linear polarized waves, with two radiator levels each comprising radiator elements mounted in lines and columns, while the elements of each radiator level are coupled on a central point so as to be equal in phase and amplitude. Both radiator levels receive and transmit mutually perpendicular polarized waves, and each radiator element has shades (6) and a linear excitrated stripline (16, 161, 16a, 16b). Said striplines (16, 161, 16a 16b) are linked in pairs to the branch ends (15, 31) of the coupling networks (1, 2), and the striplines (16, 161, 16a 16b) of each pair are mounted on the axis or arranged in an axially parallel configuration; the free ends of both striplines (15, 161, 16a, 16b) are connected through at least one connection line (32, 33, 34, 36) to a brunch end (15, 31), and a 180° phase difference between both radiator elements (6,16) is obtained by using at least one connection line (32, 33, 34) of a stripline (16, 161, 16a, 16b).
