Radiation patterns of finite-size corner-reflector antennas

Radiation patterns were measured for corner-reflector antennas having various combinations of widths and lengths of the reflecting surfaces. The widths of these ranged from 1 to 10 wavelengths, the lengths from 0.5 to 5 wavelengths. The aperture angle was, in general, set at a value required to maximize the gain. Radiation patterns are arranged according to the size of the reflecting surfaces. The effect of the widths and lengths of the surfaces on the widths of the main lobe and on the level of the radiation to the rear is summarized in a series of curves. A corner-reflector antenna with a collinear array of dipoles was designed, constructed, and tested to have sidelobe radiation below -40-db level.
