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.
