Definitions
- the present invention mainly relates to a demultiplexer used for separating orthogonal polarized waves such as a VHF band, a UHF band, a microwave band, and a millimeter wave band.
- an orthogonal polarization demultiplexer has a circular main waveguide that transmits orthogonal polarized waves, a coupling hole provided in a radial direction for branching the circular main waveguide, and a circular main waveguide through a coupling hole.
- a rectangular sub-waveguide that extracts orthogonally polarized vertical component electromagnetic waves in the orthogonal direction, a rectangular subwaveguide that extracts orthogonally polarized horizontal component electromagnetic waves in the coaxial direction of the circular main waveguide, and a rectangular sub-guide in the coaxial direction A step converter for matching the wave tube with the circular main waveguide, orthogonal polarization formed in the circular main waveguide on the side of the rectangular sub-waveguide in the coaxial direction with respect to the coupling hole of the circular main waveguide
- a septum plate septum plate
- a septum plate septum plate
- the orthogonal polarization transmitted through the circular main waveguide is demultiplexed in the coaxial direction and the orthogonal direction by the septum plate.
- the polarization component parallel to the septum plate is reflected by the septum plate and taken out to a rectangular sub-waveguide branched orthogonally through a coupling hole. Further, the polarization of the vertical component orthogonal to the septum plate is taken out from the coaxial rectangular sub-waveguide through the step converter without being affected by the septum plate.
- mode conversion is performed from the mode of the circular main waveguide to the mode of the rectangular sub-waveguide in the step conversion unit.
- a quadrature demultiplexer when taking out the polarization of the component orthogonal to the septum plate, a part of the radio wave is reflected at the end of the septum plate, and a part of the reflected radio wave is further separated on the opposite septum. Reflects at the edge of the board. Then, the multiple reflected waves may overlap and strengthen at a certain frequency, and energy may be confined within the section of the septum plate. In such a case, as a result, periodic resonance called plate resonance occurs in the radio wave extracted from the rectangular waveguide. The frequency at which this period and plate resonance occur depends on the length of the septum plate in the coaxial direction. Therefore, in the quadrature demultiplexer, it is essential to adjust the length of the septum plate in order to efficiently extract energy in a desired band.
