| Zusammenfassung: | A phased array antenna device (2) comprises a number of antenna elements (5) arranged in a spatial distribution that is designed to allow for the phased array antenna device (2) emitting and receiving superposing radio frequency signals to and from different directions. Each antenna element (5) is positioned within a corresponding unit cell (1) of the phase array antenna device (2), whereby the unit cells (1) are arranged in a non-overlapping manner next to each other. A feeding network for transmitting the antenna signals between a common feeding point and the respective antenna element (5) comprises a number of antenna element transmission line segments (4) each running into an antenna element (5) and a corresponding number of phase shifting devices (7). The phased array antenna device (2) comprises several feeding transmission line segments (8) whereby each feeding transmission line segment (8) comprises more than two transition structures (6) distributed along the feeding transmission line segment (8), wh |
