Abstract

A device for adjusting the beam direction of a beam radiated from a stationary array of antenna elements. The device includes a feed line structure configured as a star with at least four line segments extending from a central source connection terminal at the centre of the star, to the respective feed connection terminals. The dielectric body with two different body portions, having different effective dielectric values, is displaceable between two end positions in a central, region of the device.
