Abstract
A fixture for determining RF characteristics of a dielectric medium comprises a first coupler having an RF through-window with input and output ports, the input port connectable to a waveguide input. A second coupler has an RF through-window with input and output ports, the output port connectable to an output waveguide. A plurality of rods are aligned with the axes of the input and output waveguides and connect the output port of the first coupler to the input port of the second coupler. Each rod is passable through the dielectric media and mates with the input port so as to form a continuous waveguide passing through the dielectric media.
Claims14
A fixture for determining RF characteristics of a dielectric medium, said fixture comprising:
- an input waveguide;
- a first coupler connected to said input waveguide, said first coupler having a first RF through-window with first input and output ports;
- an output waveguide;
- a second coupler connected to said output waveguide, said second coupler having a second RF through-window with second input and output ports;
- and,
- a plurality of waveguide rod means for connecting said first output port of said first coupler to said second input port of said second coupler, each of said plurality of waveguide rod means being aligned parallel to a path of electromagnetic propagation between said input and output waveguides, said each of said plurality of waveguide rod means being inserted through a corresponding aperture of said dielectric medium and being removably connected to said second input port so as to define a demountable continuous waveguide structure passing through said dielectric medium and connecting said first output port of said first coupler to said second input port of said second coupler.
