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.

A phase-controlled antenna element for antenna arrays, comprising:
- a waveguide emitter,
- a rotatable phase control element located in the waveguide emitter, the phase control element including:
- at least two polarizers configured to convert between a circularly polarized signal and a linearly polarized signal,
- a holder connected to the polarizers, the holding comprising closed-cell foam, and
- a connecting element,
- a drive unit connected via the connecting element to the phase control element, the drive unit configured to rotate the phase control element about an axis of the waveguide emitter,
- a coupler coupled to the waveguide emitter.
