Abstract
A method and apparatus for a polarizer. The apparatus comprises a dielectric rod, a first array of slots, and a second array of slots. The first array of slots and the second array of slots are formed in sidewalls of the dielectric rod. The first array of slots is substantially opposite to the second array of slots. The first array of slots and the second array of slots are configured to shift a first component orthogonal to a second component in a signal traveling through the dielectric rod by around 90 degrees with respect to each other. The dielectric rod may be a solid material or comprised of layers of dielectric substrates with metal tabs.
