This invention relates to a phase shifting device, which generally comprises of rigid chassis, in the form of an aluminium plate, which can form a ground plane for feed lines (12) printed on a printed circuit board (16), which is mounted on the chassis, a rigid RF transparent block, which is fixed to an actuator arm and mounting bolts for slidably mounting block and actuator on the chassis. A flexi circuit, or the equivalent, (18) is attached to the block and is printed with generally c-shaped conductive strips (23), which form connections at open parts of the feed lines, in such a manner that movement of the block will cause changes in the effective lengths of the feed lines (12) and hence the relative phases of antennas fed by those feed lines.

L'invention concerne u dispositif de décalage de phase comprenant généralement un châssis rigide, sous forme d'une plaque d'aluminium, pouvant former un plan de sol pour des lignes d'alimentation (12) sur une carte de circuit imprimé (16), montée sur le châssis, et un bloc transparent rigide RF, fixé à un bras actionneur et à des écrous de montage afin de fixer de façon coulissante le bloc et l'actionneur sur le châssis. Un circuit flexible (18), ou analogue, est fixé sur le bloc et généralement imprimé avec des bandes conductrices en forme de C (23), formant des connexions aux parties ouvertes des lignes d'alimentation, de telle manière que le déplacement du bloc provoque un changement des longueurs effectives des lignes d'alimentation (12) et par conséquent des phases relatives des antennes alimentées par ces lignes.
