Abstract
Mode converting signal launchers for efficient coupling signals between dielectric insular and image waveguides and TEM mode transmission lines. The launcher includes a conductive ground plane and an elongated high permittivity dielectric waveguide adjacent to the ground plane. A TEM mode transmission line provides an elongated conductive strip fixed adjacent to the dielectric waveguide such that a coupling region is formed having a length of at least two times the wavelength in the dielectric waveguide.
