1. A waveguide device comprising:
- an electrically conductive member having an electrically conductive surface;
a waveguide member having an electrically-conductive waveguide face that opposes the electrically conductive surface and an electrically-conductive side face that connects to the waveguide face, the waveguide member extending so as to face along the electrically conductive surface; and
stretches of artificial magnetic conductor on both sides of the waveguide member, wherein,the waveguide member includesa first portion extending in one direction andat least two branches extending from one end of the first portion, the at least two branches including a second portion and a third portion that extend in mutually different directions;
the second portion has a recess in a side face connecting to a side face of the first portion, the recess reaching the waveguide face; and
,as viewed from a direction perpendicular to the waveguide face, a distance from a point of intersection between the side face of the first portion and the side face of the second portion to a center of the recess is shorter than a length of the recess along a direction that the second portion extends.

Abstract
A waveguide device according to an embodiment includes an electrically conductive member having an electrically conductive surface, a waveguide member extending so as to face along the electrically conductive surface, and stretches of artificial magnetic conductor on both sides of the waveguide member. The waveguide member includes a first portion extending in one direction, and at least two branches extending in mutually different directions from one end of the first portion, the at least two branches including a second portion and a third portion. The second portion has a recess in a side face that connects to one side face of the first portion, the recess reaching the waveguide face.
