Waveguide-to-microstrip transition

摘要

The invention provides first to third dielectric substrates (1a,b,c); first to third ground conductor patterns (2a,b,c) are formed on one surface of the dielectric substrates and which have ground conductor pattern omission portions (6); a strip conductor pattern (3) formed on a surface of the first dielectric substrate (1a) opposite to the surface having the first ground conductor pattern (2a); a conductor pattern (4) for shorting of a waveguide formed so as to be continuously connected to the strip conductor pattern; connecting conductors (5a,b) for connecting the ground conductor patterns and the conductor pattern to each other within the dielectric substrates; and a waveguide (7) connected to the dielectric substrate so as to correspond to the ground conductor pattern omission portions. Also, a microstrip line is constituted by the strip conductor pattern, the ground conductor pattern, and the first dielectric substrate. Further, a dielectric waveguide shorting portion is constituted by the conductor pattern, the ground conductor patterns, and the connecting conductors.
