Abstract

See full text

An antenna device includes a transmission line for propagating high frequency signal, and a plurality of antenna elements connected to the transmission line. The transmission line includes a first plate-shaped conductor, a second plate-shaped conductor, and a third plate-shaped conductor electrically grounded, a first central conductor disposed between the first and second plate-shaped conductors, a second central conductor disposed between the second and third plate-shaped conductors, an electrically connecting member inserted in an inserting hole formed through the second plate-shaped conductor, to electrically connect the first and second central conductors together, and an electrically grounded conductor disposed adjacent to the electrically connecting member. At least one of the first and second central conductors is provided with a through hole formed adjacent to the electrically connecting member, thereby electrically connects together wiring patterns provided on both surfaces, respectively, of a dielectric substrate of the at least one of the first and second central conductors.
