The horizontal plane of projection in a perspective drawing; the horizontal plane upon which the object in the drawing rests.
1. A metal plate or a system of horizontal rods or wires mounted high on a mast, at the base of a vertical antenna, to provide a radio-frequency ground at a point several wavelengths above the surface of the earth. Also see GROUND-PLANE ANTENNA.
2. In noise and interference tests, a sheet metal structure used to simulate the skin of an aircraft or missile.
3. On a circuit board, a thin metallic sheet, usually bound to the underside, that serves as a common ground and RF shield.
