Abstract: A transit structure of a standard waveguide and a dielectric waveguide is related to connecting the dielectric dielectric waveguide to the standard waveguide. The transit structure includes: a cavity to match the dielectric waveguide and the standard waveguide, wherein the dielectric waveguide and the standard waveguide are orthogonal to each other to connect. The transit structure drastically reduces a design time by simply implementing a transit structure by using only a dielectric waveguide, a cavity and a standard waveguide on a dielectric substrate and remarkably reduces a size thereof in comparison with a conventional transit structure since all designs are finished in the size of a metal waveguide.
