Abstract:
1. An NRD guide transition, comprising: two parallel conductors; a dielectric waveguide sandwiched between the two parallel conductors, a first of the two parallel conductors being at a top of the dielectric waveguide, and a second of the two parallel conductors being at a bottom of the dielectric waveguide, and a height of the dielectric waveguide separating the two parallel conductors being less than a ½ wavelength of a wave to be propagated through the dielectric waveguide; a conductor rod adjacent to and substantially parallel with the dielectric waveguide between the two conductors; a microstrip line disposed on a dielectric material, the dielectric material being on a side surface of the conductor rod and the microstrip line disposed on a side of the dielectric material opposite to the dielectric waveguide, and a ground conductor for the microstrip line defined by the conductor rod; and a coaxial line, extending perpendicularly to a longitudinal direction of the conductor rod and parallel to the two parallel conductors, the coaxial line piercing the conductor rod and the dielectric material of the microstrip line such that the coaxial line connects the dielectric waveguide with the microstrip line.
