  • Patent number: 7907031
    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.

  • Publication number: 20100090780
    Abstract: A phase shifter includes a substrate; a signal line formed on a specific region in an upper surface of the substrate; and an air gap which is formed within the substrate and changes effective permittivity of the substrate to delay phase of a signal supplied to the signal line. The phase shifter delays a phase of a signal by controlling effective permittivity using an air gap, thereby having outstandingly low insertion loss as compared to existing phase shifters. Further, the phase shifter can be manufactured in a same length as a reference line so that the phase shifter can be in a compact size.
