Mass plane for interference antennas used on e.g. military vehicle's roof, has interference antennas installed on central and peripheral plates, where peripheral plates are movable and/or removable relative to central plate

摘要

The mass plane (1) has a central plate (2) on which an interference antenna (4) is installed, where the plate is made of conducting material. Interference antennas (6.1-6.3) are installed on peripheral plates (5.1-5.3) made of conducting material, where the peripheral plates are movable and/or removable with respect to the central plate. The peripheral plates are movable with respect to the central plate to pass from a folded position in which surfaces of the peripheral plate and the central plate are partially covered to an unfolded position, in which the plates are extended side by side.
