Abstract (en)
A system for selectively converting electromagnetic waves from circular to linear polarization or vice versa is provided. The system comprises a polarization converter including a circular waveguide (22) and a rectangular waveguide (23) for receiving or transmitting a signal. The center line (23-1) of the rectangular waveguide (23) is at substantially a right angle to the axis (22-1) of the circular waveguide (22). The unit (26) is provided comprising a metal fin (26-1) and a shorting member (27) positioned in the circular waveguide (22) at the opening of the rectangular waveguide into the circular waveguide. The fin (26-1) is at a preset distance from the shorting member (27). The fin (26-1) is movable with respect to the center line (23-1) of the rectangular waveguide (23) about the axis (22-1) of the circular waveguide (22-1) with the face thereof substantially at right angles to the axis (22-1). The fin (26-1) has a front edge positioned between the rectangular waveguide center line (23-1) and the wall (23-5) of the rectangular waveguide (23) farthest from the circular waveguide opening. Means for providing circularly polarized microwave signals to the circular waveguide are provided.
