| Zusammenfassung: | A phased array antenna device (1) comprises a number of antenna elements (2), whereby each antenna element (2) is positioned within a corresponding unit cell (3) of the phase array antenna device (1) and whereby the unit cells (3) are arranged in a non-overlapping manner next to each other. A feeding network (5) transmits the antenna signals between a common control unit (4) and the respective antenna element (2), whereby the feeding network (5) comprises a number of antenna element transmission line segments (10) each running into an antenna element (2), and with a number of phase shifting devices (11), whereby for each antenna element (2) a corresponding phase shifting device (11) is arranged along the respective antenna element signal transmission line (10) that runs into said antenna element (2). The phased array antenna device (1) comprises several feeding transmission line segments (7) whereby each feeding transmission line segment (7) comprises more than two transition structures (9) distributed along |
