ABSTRACT:
A stripline or microstrip feed system distributes electromagnetic power among a set of utilization devices such as the radiators of an array antenna. In the feed system, elongated assemblies of microwave couplers 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 allowing beam steering in a direction perpendicular to the rows. In each assembly of couplers, different forms of couplers are employed to provide both an amplitude taper and a phase taper to the radiations of the respective radiators in each row of radiators. The couplers include the Wilkinson coupler, the hybrid coupler, and the backward wave coupler which serve as power dividers during transmission. There is a feeding of the output signal of one coupler, via a first coupler output terminal to a next coupler in a series of couplers, while the remainder of the power is fed via a second coupler output terminal to a radiator of the antenna. In each coupler assembly there is a main conductor which interconnects a plurality of the couplers to provide a configuration of coupler assembly having a desired narrow width, less than approximately one free-space wavelength.
