Abstract (en)

The device consist of half-wavelength dipoles (active elements) (1) and four indirectly fed slots (6) (parasite elements), where these slots are excited by the active elements, which are connected to a supply line (4). The scope of the device is to control the radiating pattern of a dipole array through the slots (6). The invention pertains to the field of antennae, and more precisely to that of microwave antennae. It may be adopted in stand-alone or in integrated applications on reflector antennae for air traffic control, where detection is performed in the S band, associated with an interrogation performed in L band, obtained by inserting the innovative device into an existing feed so as to achieve a control over the radiating pattern of the entire radiating system or antenna, according to the application. <IMAGE>
