摘要： A phased array antenna device includes at least one antenna element arranged in a spatial distribution to emit and receive superposing radio frequency signals to and from different directions. Each antenna element is positioned within a corresponding unit cell. The unit cells 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 includes a plurality of antenna element transmission line segments each running into an antenna element and a corresponding plurality of phase shifting devices. The feeding transmission line segments each includes more than two transition structures distributed along the feeding transmission line segment. Each transition structure provides for a signal coupling between the feeding transmission line segment and the corresponding antenna element transmission line segment, thereby connecting several antenna element transmission line segments with the same feeding transmission line segment.
