摘要： The present invention relates to a device for adjusting the beam direction of a beam radiated from a stationary array of antenna elements, wherein at least two antenna element feed points are coupled to a common signal source via a feed line structure having a source connection terminal to be connected to said source and at least two feed connection terminals to be connected to said antenna element feed points, said feed line structure being at a distance from and in parallel to a fixed ground plane on at least one side of said feed line structure, wherein a movable element is located adjacent to said feed line structure so as to change the signal phase of signal components being transferred between said source connection terminal and the respective feed connection terminals, said movable element being movable for effecting a controlled phase shift of said signal components so as to adjust said beam direction. The device is provided with detection means for detecting the absolute position of the movable element.

Antenna element feed points are coupled to a common source via a feed line structure having a source connection and feed connection terminals to be connected to the antenna element feed points, the feed line structure being at a distance from and in parallel to a fixed ground plane. A movable element is located adjacent to the feed line structure to change the signal phase of signal components being transferred between the source connection and the respective feed connection terminals. The movable element is movable for effecting a phase shift of the signal components to adjust the beam direction. The device is provided with a detection arrangement for detecting the absolute position of the movable element.
