Abstract
A phase-controlled antenna element includes a waveguide emitter with signal output or signal injection, into which a rotatable phase control element is introduced, and a drive unit. The phase control element comprises in this case a holder, at least two polarizers which are fastened to the holder, and a connecting element. Each of the at least two polarizers can convert a circularly polarized signal into a linearly polarized signal. The phase control element is rotatably fitted in the waveguide emitter and is connected to the drive unit with the aid of the connecting element in such a manner that the drive unit can rotate the phase control element about the axis of the waveguide emitter.
