Design of a Connector for Connecting a Dielectric Waveguide and a Rectangular Waveguide

Dielectric waveguides are transmission lines that have lower losses than coaxial cables at frequencies above millimeter waves. However, when connecting dielectric waveguides to network analyzers for experiments, mode conversion is required due to the different propagation modes between dielectric waveguides and coaxial connectors or rectangular waveguides. In this paper, we report the design of a connector that performs mode conversion to connect a dielectric waveguide and a rectangular waveguide.
