1. A waveguide device comprising:
- a first electrically conductive member having a first electrically conductive surface;
a first waveguide member having an electrically-conductive first waveguide face opposing the first electrically conductive surface, the first waveguide face having a stripe shape extending along the first electrically conductive surface;
a plurality of first electrically conductive rods on both sides of the first waveguide member, each having a leading end opposing the first electrically conductive surface;
a second electrically conductive member having a second electrically conductive surface;
a second waveguide member having an electrically-conductive second waveguide face opposing the second electrically conductive surface, the second waveguide face having a stripe shape extending along the second electrically conductive surface; and
a plurality of second electrically conductive rods on both sides of the second waveguide member, each having a leading end opposing the second electrically conductive surface, wherein,a first waveguide gap exists between the first waveguide face and the first electrically conductive surface;
a second waveguide gap exists between the second waveguide face and the second electrically conductive surface;
one end of the first waveguide gap is connected to the second waveguide gap;
at least one of the first waveguide face and the first electrically conductive surface is connected at one end to at least one of the second waveguide face and the second electrically conductive surface; and
at a connecting portion between the one end of the first waveguide gap and the second waveguide gap, the first waveguide face extends in a direction that intersects a plane which is parallel to the second electrically conductive surface.

Abstract
A waveguide device includes: a first conductive member having a first conductive surface; a first waveguide member having a first waveguide face opposing the first conductive surface; a plurality of first conductive rods on both sides of the first waveguide member; a second conductive member having a second conductive surface; a second waveguide member having a second waveguide face opposing the second conductive surface; and a plurality of second conductive rods on both sides of the second waveguide member. A first waveguide gap exists between the first waveguide face and the first conductive surface. A second waveguide gap exists between the second waveguide face and the second conductive surface. One end of the first waveguide gap is connected to the second waveguide gap, and at a connecting portion therebetween, the first waveguide face extends in a direction that intersects a plane which is parallel to the second conductive surface.
