Abstract
An improved corporate feed network for distributing radio frequency energy to elements of an antenna array is shown. The corporate feed network comprises an improved feed coupler, including a quadrature hybrid junction for dividing radio frequency (R.F.) energy from an input port into the two waveguides and a plurality of secondary waveguides disposed orthogonally to the first and second waveguides, each of the secondary waveguides having narrow walls common to broad walls of the first and second waveguides with apertures formed through common sections of such walls, the common sections being offset to impart directional characteristics to the corporate feed network.
