To ensure antenna gain in a band from a VHF band to a UHF band.SOLUTION: A window glass attached to a window frame formed on a vehicle body includes a glass plate, a dielectric having a first surface on the side facing the glass plate, and a second surface on the side opposite to the first surface, a planar conductor arranged between the glass plate and the first surface, a defogger provided on the side of the second surface and facing the planar conductor via the dielectric, a feeding unit provided on the side of the second surface and located outside the first side of the defogger, and a non-feeding conductor provided on the side of the second surface and located outside the second and third sides of the defogger, and the window frame includes a metal unit arranged along the outer edge of the dielectric on the side of the second surface with respect to the dielectric, and the feeding unit faces the planar conductor via the dielectric, and the non-feeding conductor extends along the second side and the third side and is electrically connected to the metal unit.SELECTED DRAWING: Figure 1

    【課題】VHF帯からUHF帯までの帯域におけるアンテナ利得の確保。【解決手段】車体に形成される窓枠に取り付けられる窓ガラスは、ガラス板と、前記ガラス板に対向する側の第1面と、前記第1面とは反対側の第2面とを有する誘電体と、前記ガラス板と前記第1面との間に配置される平面状導体と、前記第2面の側に設けられ前記誘電体を介して前記平面状導体に対向するデフォッガと、前記第2面の側に設けられ、前記デフォッガの第1辺の外側に位置する給電部と、前記第2面の側に設けられ、前記デフォッガの第2辺及び第3辺の外側に位置する無給電導体と、を備え、前記窓枠は、前記誘電体に対して前記第2面の側で前記誘電体の外縁に沿って配置される金属部を有し、前記給電部は、前記誘電体を介して前記平面状導体に対向し、前記無給電導体は、前記第2辺及び前記第3辺に沿って延伸し、前記金属部に電気的に接続される。【選択図】図1
