WAVEGUIDE DEVICE AND ANTENNA DEVICE INCLUDING THE WAVEGUIDE DEVICE

摘要

A waveguide device includes: a first conductive member having an electrically conductive surface; a second conductive member having a plurality of electrically conductive rods arrayed thereon, each conductive rod having a leading end opposing the conductive surface; and a waveguide member having an electrically conductive waveguide face opposing the conductive surface, the waveguide member being disposed among the conductive rods and extending along the conductive surface. The waveguide member includes at least one of a bend and a branching portion. A measure of an outer shape of a cross section of at least one of the plurality of conductive rods that is adjacent to the bend or the branching portion, taken perpendicular to an axial direction of the at least one conductive rod, monotonically decreases from a root that is in contact with the second conductive member toward a leading end.

1. A waveguide device comprising:
a first electrically conductive member having an electrically conductive surface which is shaped as a plane or a curved surface; a second electrically conductive member having a plurality of electrically conductive rods arrayed thereon, each electrically conductive rod having a leading end opposing the electrically conductive surface of the first electrically conductive member; and a waveguide member having an electrically conductive waveguide face opposing the electrically conductive surface of the first electrically conductive member, the waveguide member being disposed among the plurality of electrically conductive rods and extending along the electrically conductive surface, wherein, the waveguide member includes at least one of a bend at which the direction that the waveguide member extends changes and a branching portion at which the direction that the waveguide member extends ramifies into two or more directions; and a measure of an outer shape of a cross section of at least one of the plurality of electrically conductive rods that is adjacent to the bend or the branch, taken perpendicular to an axial direction of the at least one electrically conductive rod, monotonically decreases from a root that is in contact with the second electrically conductive member toward the leading end.
