Abstract
A polarizer apparatus for RF communications including an in-line waveguide switch having a first port with a rectangular waveguide shape, and a second port having a circular waveguide shape. The waveguide switch includes a plurality of rotatable disks coupled and arranged between the input and output of said waveguide switch, each of the disks having an opening provided therein which defines at least a portion of a signal path configured to allow RF signals to propagate therethrough. The waveguide switch includes an actuating mechanism arranged to rotate the disks to positions relative to each other which modify the polarization of RF signals propagating through the openings. The polarizer apparatus includes a feed coupled to the output of the waveguide switch, the feed including a vane polarizer arranged to circularly polarize signals provided thereto from the output of the waveguide switch.
