よく変換することは難しい。The direction 15 of the electric field of the ridge waveguide (the arrow schematically shows the direction of the electric field) is concentrated on the ridge portion and the H-plane of the waveguide as shown in FIG. 2, and has a distribution close to the TEM mode. , The conversion with the microstrip line is easily performed.
However, in the coplanar line with the ground conductor on the back side, as shown in FIG. 3, since the outer conductor 9 is on the same plane as the central conductor 8, a horizontal electric field component 16 is present. Therefore, it is difficult to efficiently convert the waveguide mode by connecting the conventional ridge waveguide.

The resulting electric field distribution is close to that of a coplanar line with a backside ground conductor. Therefore, the waveguide mode can be directly converted into the coplanar line with the backside ground conductor without using the microstrip line.
