a flat reflective surface, like steel or water, that helps improve the performance of some designs of antennas
a shielded room wall, a conduit box, the equipment housing, or other container
A conductor layer, or portion of a conductor layer, used as a common reference point for circuit returns, shielding, or heat sinking.
An electrically conductive surface that serves as the near-field reflection point for an antenna. Note: A ground plane may consist of a natural (e.g., Earth or sea) surface, an artificial surface of opportunity (e.g., the roof of a motor vehicle), or a specially designed artificial surface (e.g., the disc of a discone antenna).
A conducting layer in, or on, a substrate providing a grounding, or reference, point for components. There may be several ground planes separated by insulating layers.
Usually an imaginary plane used as the horizontal reference plane.
The earth or negative rail of a circuit. A large or significant mass that presents the effect of earth (ground) to a signal.
A large flat metal surface, or electrically charged field, surrounding a GPS antenna used to deflect errant signals (multipath) reflected from the ground and other near-by objects.
A large area of solid or hatched copper on a printed circuit board used as an electrical ground or shield. | | | | | | | | | J | K | L | | | | | | | | W | X | Y | Z
A conductive plane as a common ground reference in a multilayer PCB for current returns of the circuit elements and shielding.
A copper plane connected to ground
A man made system of conductors placed below an antenna to serve as an earth ground.
A conductor layer that covers all or a large portion of a board (with suitable clearances around through-holes and vias), and which is used as a common reference point for circuit returns, shielding or heat sinks. The similar power plane distributes power to circuitry on the board. Both ground and power planes may also be used as an electromagnetic shield and as a reference plane for high-frequency ( stripline) circuitry.
In electrical engineering, a ground plane is an electrically conductive surface.
