INNER-TUBE WITH OPPOSING SHALLOW-CAVITIES FOR USE IN COAXIAL POLARIZER

摘要

PROBLEM TO BE SOLVED: To provide a coaxial polarizer which does not require complex machining processes.SOLUTION: A coaxial polarizer includes an outer-conductive tube, an inner-conductive tube 130 positioned within and axially aligned with the outer-conductive tube, and two dielectric bars 160-1, 160-2 each having a flat-first surface. The inner-conductive tube 130 has two shallow-cavities 162-1, 162-2 on opposing portions of an outer surface 230 of the inner-conductive tube 130. The shallow-cavities 162-1, 162-2 each have at least one planar area having a cavity length parallel to the Z axis and a cavity width perpendicular to the Z axis and to a radial direction of the inner-conductive tube 130.
