Image antenna

Due to its image in the ground plane (dotted lines), a monopole antenna has the same radiation pattern over perfect ground as a dipole antenna in free space with twice the voltage

In telecommunications and antenna design, an image antenna is an electrical mirror-image of an antenna element formed by the radio waves reflecting from a conductive surface called a ground plane, such as the surface of the earth. It is used as a geometrical technique in calculating the radiation pattern of the antenna.
