ABSTRACT OF THE DISCLOSURE The invention regards a device which improves the efficiency of a radiating system by means of parasite elements formed on the- ground plane, which consist of half-wavelength dipoles (active elements) (1) and four directly fed slots (2) (parasite elements) where these slots are excited by the active elements, Which are connected to supply line (4). The scope of the active is to control the radiating pattern of a dipole array through the slots(2). The invention pertain to the field of antennas, and more precisely to that of microwave antennas. It may be adopted in standalone or in integrated applications on reflections for air traffic control, where detection is performed in the S band, associated with an interrogation performed in L band, tained by inserting the innovative device into an existing feed so as to achive a control over the radiating pattern of the en- tire radiating system or antenna, according to the application.
