Polarization coupler |
摘要 |
A polarization coupler includes: connector waveguide that connects circular waveguide with quadrangular waveguide arranged in an axial direction of circular waveguide and having short side shorter than an inner diameter of circular waveguide; flat conductor wall formed over connector and circular waveguides, and dividing the inside of connector and circular waveguides arranged parallel to an extending direction of long side of quadrangular waveguide; first inclined surface formed on inner wall of connector waveguide at a position facing one surface of conductor wall, and inclined toward conductor wall as coming closer to quadrangular waveguide; second inclined surface formed on the inner wall of connector waveguide at a position facing the other surface of conductor wall, and inclined toward conductor wall as coming closer to quadrangular waveguide; and coupling hole, formed in circular waveguide, for extracting one polarization-divided by conductor wall out of electromagnetic waves propagated through circular waveguide. |

1. A polarization coupler comprising:
a circular waveguide; a quadrangular waveguide that is arranged in an axial direction of the circular waveguide, and has a short side shorter than an inner diameter of the circular waveguide; a connector waveguide that connects the quadrangular waveguide with the circular waveguide; a flat conductor wall that is formed over the connector waveguide and the circular waveguide, and divides the inside of the connector waveguide and the circular waveguide arranged parallel to a direction where a long side of the quadrangular waveguide extends; a first inclined surface that is formed on an inner wall of the connector waveguide at a position facing one surface of the conductor wall, and inclined toward the conductor wall as coming closer to the quadrangular waveguide; a second inclined surface that is formed on the inner wall of the connector waveguide at a position facing the other surface of the conductor wall, and inclined toward the conductor wall as coming closer to the quadrangular waveguide; and a coupling hole that is formed in the circular waveguide, and extracts one that is polarization-divided by the conductor wall out of electromagnetic waves propagated through the circular waveguide, wherein the connector waveguide is configured by: an arc-shaped first wall surface; an arc-shaped second wall surface that faces the first wall surface; the first inclined surface; and the second inclined surface. |
