PROBLEM TO BE SOLVED: To provide an antenna member having a coplanar waveguide for vehicle-to-vehicle radio communication.SOLUTION: An antenna member 100 includes a substrate 110, a first conductor 120 and a second conductor 130. The substrate at least includes a first lateral direction surface. The first conductor is disposed on the first lateral direction surface, and includes a feeder line unit 121 and a monopole unit 122. The second conductor is disposed at least partially on the same first lateral direction surface, and includes: two ground planes 131, 132 disposed on the first lateral direction surface in a manner adjacent to the feeder line unit of the first conductor on both sides of the feeder line unit; and two stubs 133, 134 respectively disposed on both sides of the two ground planes on the first lateral direction surface, and extending in a direction parallel to the feeder line unit of the first conductor. The two ground planes and the two stubs of the second conductor are disposed to form the coplanar waveguide. 【課題】車対車の無線通信用のコプレーナ導波路を備えるアンテナ部材を提供する。【解決手段】アンテナ部材１００は、基板１１０と、第１の導体１２０及び第２の導体１３０とを備える。基板は少なくとも第１の横方向表面を有する。第１の導体は、第１の横方向表面上に設けられ、給電線部１２１及びモノポール部１２２を含む。第２の導体は、同一の第１の横方向表面上に少なくとも部分的に設けられ、第１の横方向表面上に第１の導体の給電線部に隣接して給電線部の両側に設けられた２つの接地プレーン１３１、１３２と、第１の横方向表面上に前記２つの接地プレーンの各々の両側に配置され、第１の導体の給電線部に平行な方向に延在する２つのスタブ１３３、１３４とを含む。第２の導体の２つの接地プレーン及び２つのスタブは、コプレーナ導波路を形成するように配置される。【選択図】図１
