A phased array antenna device comprises antenna elements positioned within a corresponding unit cell. The unit cells are arranged non-overlappingly next to each other. A feeding network transmits antenna signals between a common control unit and the respective antenna element. The feeding network comprises a plurality of antenna element transmission line segments, each running into an antenna element, and a plurality of phase shifting devices. Several feeding transmission line segments, each comprising more than two transition structures are provided. Each transition structure couples a signal into a corresponding antenna element transmission line segment. The transition structure for an antenna element transmission line segment that runs into a unit cell is positioned in the direction of the feeding transmission line segment passing by or traversing this unit cell at a phase shifting distance that is larger than an extension of the unit cell measured in this direction.
