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.

A concentric feed is provided. The concentric feed includes an outer-conductive tube electrically connected at a base of an inner-conductive tube to an outer-conductive tube by a process comprising the steps of: configuring the outer-conductive tube; configuring the inner-conductive tube; and positioning the outer-conductive tube to contact the inner-conductive tube at the base. The outer-conductive tube is configured to include: a side-port; a first-edge surface; a first-interior surface sharing an edge with and perpendicular to the first-edge surface; a second-edge surface; and a second-interior surface sharing an edge with and perpendicular to the second-edge surface. The inner-conductive tube is configured to include: the base at a base-end of the inner-conductive tube, the base including a first lip and a second lip protruding orthogonal to a first surface and a second surface, respectively, and a central-port centered on the central axis and parallel to the central axis; and a main-body.
