KOAXIAL-/HOHLLEITER-UMSETZER

摘要

A circular waveguide (10) is open at one end (11) for the introduction of electromagnetic waves and closed at its other end by a short-circuiting wall (12) and a conducting rod (14) is attached to the short-circuiting wall (12) so that the rod (14) is disposed along the axial line (10a) of the circular waveguide. Two probes (17, 18) to pick up coaxial-mode electric signals from waveguide-mode waves are disposed on a plane perpendicular to the axial line (10a) of the circular waveguide so that the axial lines of the respective probes intersect at right angles on the axial line. When waveguide-mode vertically polarized and horizontally polarized waves come into the circular waveguide, a coaxial-mode electric signal is induced from the vertically polarized wave in one of the probes and another coaxial-mode electric signal is induced from the horizontally polarized wave in the other of the probes. <IMAGE>
