An area of copper on a PCB which is connected to the PCB's ground node in order to provide a return path for current from the various circuits on the board. The ground plane's area is typically made as large as possible (even occupying an entire board layer) in order to minimize its impedance, thus allowing it to conduct high return currents without a significant voltage drop from one part of the board to another. Use with related tags such as "pcb".
