Abstract (en)
[origin: WO2013044032A1] A microwave transmit/receive enclosure comprises an enclosure housing including an opening and a waveguide rotator that is mounted on the enclosure housing and near the opening. In particular, the waveguide rotator includes a plurality of rectangular openings that are perpendicular to a predefined axis and there is a predefined incremental rotation angle between two immediately adjacent rectangular openings with respect to an axis that is perpendicular to the predefined axis. The waveguide rotator is configured such that a sum of the incremental rotation angles between the plurality of rectangular openings causes a change of orientation to a radio signal that is transmitted through the waveguide rotator such that it aligns with a polarization change in the antenna.
