Abstract:
1. A transition for transmitting a mm-wave signal from one plane to another, said transition comprising: first and second transmission lines on parallel planes; a waveguide orthogonal to said first and second transmission lines, wherein said first and second transmission lines are suitable for transmitting a TEM mode signal and said waveguide is suitable for transmitting a waveguide mode signal; a support plate between said first and second transmission lines, said support plate defining a borehole with conductive walls between said first and second transmission lines; a metalized dielectric filler comprising at least one conductive layer and being disposed in said borehole such that said conductive layer and at least a portion of said conductive walls of said borehole form said waveguide, whereby said waveguide is smaller than said borehole.
