Gains of finite-size corner-reflector antennas

An experimental comer reflector was erected at the Table Mesa antenna range near Boulder. The aperture angle of this antenna was made adjustable to any value between 20 and 180 degrees. The widths and lengths of the reflecting surfaces were each adjustable from 0.4 to 5.0 wavelengths. Measurements of gain were made for numerous combinations of lengths and widths of reflecting surfaces. These measurements were made with a half-wave dipole in the first, second and third maximum positions. The aperture angle was adjusted to maximize the gain. The principal results are presented in the form of contours of constant gain plotted for a range of widths and lengths of reflecting surfaces from 0.4 to 5.0 wavelengths. These graphs should be useful to a designer of corner-reflector antennas.
