Corner Reflector
An antenna comprised of one or more dipole elements in front of a corner reflector, called the corner-reflector antenna, is illustrated in figure 12. A photograph of a typical corner reflector is shown in figure 13.

This antenna has moderately high gain, but its most important pattern feature is that the forward (main beam) gain is much higher than the gain in the opposite direction. This is called the front-to-back ratio and is evident in the pattern shown in figure 14.
