A directional antenna consisting of the combination of a reflector comprising two conducting planes forming a dihedral angle and a driven radiator or dipole which usually is in the bisecting plane. It is widely used both singly and in arrays, gives good gain in comparison with cost, and covers a relatively wide band of frequency. Corner reflector antennas are used in very high-frequency (VHF) and ultrahigh-frequency (UHF) communications systems, telemetry systems, and electronic intelligence gathering systems.
