Abstract: A stripline or microstrip feed system (10) distributes electromagnetic power among a set of utilization devices such as radiators (22) of an array antenna. In the feed system, elongated assemblies of microwave couplers (38) are arranged side by side to provide for a two-dimensional array of couplers corresponding to a two-dimensional array of radiators in rows and columns of an array antenna, and providing beam steering perpendicular to the rows. Each coupler assembly comprises different forms of couplers for providing both an amplitude and phase taper for the radiation radiating from each row of radiators. The couplers include a Wilkenson coupler (44), a hybrid coupler (46), and a backward wave coupler (48) which serve as power dividers during transmission. The couplers (44, 46, 48) are connected in series, and wherein a particular coupler has a first output terminal (e.g. T2) coupled to an input terminal (T1) of a next coupler while a second output terminal (e.g. T3) of the particular coupler is connected to a radiator of the antenna array. Each coupler assembly has a main conductor (60) which interconnects the couplers to provide a configuration having a narrow width which is less than approximately one free-space wavelength.
