The invention re-lates to an improved high-frequency phase shifter unit characterized by the following new features: at least another additional stripline section (21b, 21c, 21d) which is arranged concentrically in relation to the first stripline section (21 a) is provided; additional connecting lines (31b; 31c, 31d) are provided, whereby an electrical connection exists at least indirectly from the supply line (13) to the pick-off section (27a - 27d) to which at least one corresponding stripline section (21a, 21b, 21c, 21d) is assigned; at least two different pairs of antenna radiators (1a, 1b, 1c, 1d, 1e, 1f) can be controlled with different phase angles (.PHI.) in the pick-off sections (39a, 39b) which are misaligned in relation to one another on the at least two stripline sections (21a, 21b, 21c, 21d); the various connecting lines (31a - 31d) are mechanically connected to one another.

Ensemble déphaseur à haute fréquence amélioré caractérisé en ce qu'il comporte au moins un segment de guide d'ondes à ruban supplémentaire (21b, 21c, 21d) placé de préférence concentriquement par rapport au premier segment (21a) de premier guide d'ondes à ruban, en ce qu'il comprend des lignes de raccordement supplémentaires (31b; 31c, 31d), ce qui permet le raccordement électrique tout au moins indirect entre la ligne d'alimentation (13) et chaque segment de branchement (27a - 27d) associé à un segment de guide d'ondes à ruban (21a, 21b, 21c, 21d), en ce qu'au moins deux paires différentes de radiateurs (1a, 1b, 1c, 1d, 1e, 1f) d'antenne, commandés par des angles de phase (.phi.) différents, peuvent être raccordées aux deux segments de guide d'ondes à ruban au moins (21a, 21b, 21c, 21d) à des sites de branchement (39a, 39b) situés de manière décalés l'un par rapport à l'autre et en ce que les lignes de raccordements (31a - 31d) sont reliées mécaniquement les unes aux autres.
