PROBE FOR CROSS DOUBLE POLARIZATION WAVEGUIDE INPUT DEVICE, CROSS DOUBLE POLARIZATION WAVEGUIDE INPUT DEVICE USING THIS PROBE, AND CONVERTER FOR SATELLITE BROAD CAST RECEPTION USING THIS INPUT DEVICE
PROBLEM TO BE SOLVED: To obtain a cross double polarization waveguide input device, a probe for this device, and a converter for satellite broadcast reception which have simple circuit design and can obtain satisfactory reception characteristics. ;SOLUTION: A probe 7 of a cross double polarization waveguide input device includes a center conductor 9 which is so formed that a front end 9a may project at about right angles to the axial direction, a non-dielectric layer 10 which is formed to cover the center conductor 9 so that the front end 9a of the center conductor 9 may be exposed, and a conductive layer 11 which is formed in a preliminarily determined range on the surface on the front end side of the non-dielectric layer 10. This prove 7 is inserted to an aperture of a waveguide- side in the axial direction to be able to receive a polarized wave perpendicular to the axial direction. Since the face of the non-dielectric layer 10 which is exposed to a cavity part remaining after insertion of the probe is covered with the conductive layer 11, the probe can be constituted in accordance with the impedance of polarization.;COPYRIGHT: (C)2000,JPO
