This report considers an array of reactively loaded aperture antennas, specifically, an N element array of closely-spaced waveguide-backed rectangular slots. Only the center waveguide is fed and the other waveguides are short circuited to provide the reactive loads. The positions of the short circuits are chosen to obtain maximum antenna gain in some specified direction. By varying the positions of the short circuits a directive beam can be steered through 180 deg. space. Both seven and nine element arrays are considered explicitly. Feasibility for physical realization of the reactive loading is discussed. A computer program with operating instructions is included. Author
