Abstract:

A line source array was designed and built to illuminate a spherical reflector 500 ft in diameter. The spherical aberration is corrected by controlling the phase along the line source by uniformly spaced cylindrical posts periodic structure and by varying the width of the waveguide along the source. The amplitude of the radiation from the line source is controlled by probe-coupled monopoles. Design, test procedure, and results at 2840 Mc are presented. Author
