Abstract: According to the present invention an antenna support structure for at least three directional antenna sub-systems provided, wherein the antenna sub-systems can be preferably planar antenna arrays. The antenna support structure (1) comprises at least four panels (3, 4) adapted to support respectively one of the antenna sub-systems (2). The panels (3, 4) include a main panel (3) and at least three secondary panels (4) respectively adjacent to the main panel (3). The secondary panels (4) can be respectively attached by hinge means (5) to the main panel (3). Therefore the secondary panels (4) can be individually adjusted in a predetermined angle to the main panel (3). The antenna support structure according to the present invention can be particularly used in combination with wide-band printed dipole antennas for micro-wave and millimeter-wave applications.
Abstract: The invention relates to novel .alpha.-fluoroacrylic acid derivatives, to active compound/antidote combinations which comprise .alpha.-fluoroacrylic acid derivatives and are outstandingly suitable for use in crops of useful plants, to their use and to methods for protecting crop plants.
