Abstract:
1. A waveguide-to-microstrip transition, comprising: a dielectric substrate; a ground conductor pattern which is disposed on one surface of the dielectric substrate and which has a ground conductor pattern omission portion; a strip conductor pattern disposed on a surface of the dielectric substrate opposite to the surface having the ground conductor pattern; a conductor pattern for shorting of a waveguide disposed so as to be continuously connected to the strip conductor pattern; connecting conductors for connecting the ground conductor pattern and the conductor pattern for shorting of a waveguide to each other within the dielectric substrate wherein the connecting conductors are constituted by a plurality of vias; and a waveguide connected to the dielectric substrate so as to correspond to the ground conductor pattern omission portion, wherein a microstrip line is constituted by the strip conductor pattern, the ground conductor pattern, and the dielectric substrate, and a dielectric waveguide shorting portion is constituted by the conductor pattern for shorting of a waveguide, the ground conductor pattern, and the connecting conductors; wherein a cutout portion is provided in the conductor pattern for shorting of a waveguide.
