Abstract: An antenna features a plurality of single emitters which in the x- and y-direction form an antenna array with an aperture. The single emitters are separated from each other by separating walls. At least a portion of the separating walls features an interference site that interrupts the otherwise planar aperture in the z-direction. However, the separating walls which cross the x-direction (and thus separate neighboring single emitters in the x-direction) differ from the separating walls in the y-direction with respect to their wall thickness. In addition, the single emitters feature a separation in the x-direction of less than A. The x-, y- and z-directions are each aligned orthogonal to each other. Due to the asymmetrical wall thickness the single emitters in the x-direction can be placed more closely to each other, so that when using the phase-controlled single emitters the emission characteristic can be displaced in this x-direction.

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.

Abstract: A controllable phase control element comprises a drive unit and a holder, to which at least two polarizers are attached, which are arranged one behind the other in the direction of incidence of a wave. Each polarizer is designed in such a way that the polarizer can convert a circularly polarized signal into a linearly polarized signal. The drive unit is designed in such a way that the holder and thus the polarizers can be mounted over a freely selectable angular range.

Abstract: A phase-controlled antenna array comprises at least four phase-controlled elements which are connected via a feed network. Each antenna element comprises a waveguide emitter with a signal output coupling or input coupling and a phase actuator which is rotatably attached in the waveguide emitter and contains a mounting and two polarizers, wherein each of the two polarizers can convert a circularly polarized signal into a linearly polarized signal. The antenna elements additionally comprise a connection element and a drive unit which is attached to a support and which is connected to the phase actuator via the connection element such that the drive unit can rotate the phrase actuator about an axis of the waveguide emitter. The antenna array additionally comprises a computing unit which is connected to the drive unit(s) of the phase-controlled antenna elements via control lines and which adjusts the rotation of each phase actuator.
