Abstract
An integral waveguide device herein includes a polarizer component comprising a waveguide and a dielectric slab, the dielectric slab configured to change a polarization of a signal passing through the waveguide. The integral waveguide device also includes a feed horn for conveying signals between the waveguide and a parabolic antenna. The waveguide of the polarizer and the feed horn are manufactured as an integral component with the feed horn disposed at a first end of the waveguide.
Claims19
An integral waveguide device comprising:
- a polarizer component comprising a waveguide and a dielectric slab, the dielectric slab configured to change a polarization of a signal passing through the waveguide;
- and
- a feed horn for conveying signals between the waveguide and a parabolic antenna, wherein:
- the waveguide of the polarizer component and the feed horn are formed manufactured as an integral component with the feed horn disposed at a first end of the waveguide,
- the dielectric slab is configured to be inserted into an axial void that traverses a length of the waveguide,
- the waveguide includes a plurality of first apertures in a wall of the waveguide defining a first position surrounding the axial void and a plurality of second apertures in the wall of the waveguide defining a second position surrounding the axial void, and
- the dielectric slab includes a plurality of tabs configured to engage with the plurality of first apertures or the plurality of second apertures respectively when the dielectric slab is placed in the first position or the second position to hold the dielectric slab within the waveguide.
A method for manufacturing an integral waveguide device comprising:
- forming the integral waveguide device in a single piece, the integral waveguide device comprising a waveguide of a polarizer component and a feed horn, the feed horn disposed at a first end of the waveguide;
- and
- inserting a dielectric slab into the waveguide of the polarizer component, the dielectric slab is configured to change a polarization of a signal passing through the waveguide;
- wherein:
- the dielectric slab is configured to be inserted into an axial void that traverses a length of the waveguide,
- the waveguide includes a plurality of first apertures in a wall of the waveguide defining a first position surrounding the axial void and a plurality of second apertures in the wall of the waveguide defining a second position surrounding the axial void, and
- the dielectric slab includes a plurality of tabs configured to engage with the plurality of first apertures or the plurality of second apertures respectively when the dielectric slab is placed in the first position or the second position to hold the dielectric slab within the waveguide.
