Abstract: A coaxial polarizer is provided. The coaxial polarizer includes an outer-conductive tube, an inner-conductive tube positioned within and axially aligned with the outer-conductive tube, and two dielectric bars each having a flat-first surface. The inner-conductive tube has two shallow-cavities on opposing portions of an outer surface of the inner-conductive tube. The shallow-cavities each have at least one planar area having a cavity length parallel to a Z axis and a cavity width, including a minimum width, perpendicular to the Z axis and to a radial direction of the inner-conductive tube. The flat-first surface has a dielectric length and width that are parallel and perpendicular to the Z axis, respectively. The dielectric length and dielectric width are less than the cavity length and the minimum width, respectively. The two flat-first surfaces of the respective two dielectric bars contact at least a portion of the respective two planar areas of the two shallow-cavities.
