Abstract:
A conversion portion structure for first and second non radiative dielectric waveguides for connecting a first non radiative dielectric waveguide, comprising a dielectric strip provided between two opposing conductive plates, to a second non radiative dielectric waveguide, comprising two conductive plates, having grooves provided therein at opposing positions, and a dielectric strip inserted between the opposing grooves, comprising:a first conversion portion, wherein a width of a dielectric strip therein is changed from a width of said dielectric strip of said second non radiative dielectric waveguide to a width of said dielectric strip of said first non radiative dielectric waveguide;a second conversion portion, having grooves of substantially the same depth as said grooves in said second non radiative dielectric waveguide, and a dielectric strip of substantially the same width as said dielectric strip of said first non radiative dielectric waveguide; anda third conversion portion, comprising a portion wherein said grooves of said second conversion portion widen in a direction roughly perpendicular to the direction of electromagnetic wave propagation and parallel to faces of said conductive plates, and further comprising said dielectric strip of said first non radiative dielectric waveguide.
