PROBLEM TO BE SOLVED: To realize a vehicle antenna device capable of gaining an excellent antenna characteristic without limiting degree of freedom in designing antennas while suppressing an influence on the appearance of the vehicle.SOLUTION: A window frame 10 includes: a resin panel 100 attached to the vehicle outer side of a door frame 34; an antenna 200 built in the resin panel 100; and a window guide 36 fitted into the edge part of the resin panel 100 and holding the edge part of the rear window 32. As a material of the widow guide 36, a resin with a dielectric dissipation factor is 0.67 or less is used.
【課題】アンテナを設計する場合の自由度が限定されることなく、車両の外観への影響を抑制しつつ、良好なアンテナ特性を得ることが可能な車両用のアンテナ装置を実現する。【解決手段】本発明の一形態に係る窓フレーム10は、ドアフレーム34の車外側に取り付けられる樹脂パネル100と、樹脂パネル100に内蔵されたアンテナ200と、樹脂パネル100の縁部に嵌め込まれ、後部窓32の縁部を把持するウインドガイド36とを備え、ウインドガイド36の材料として、誘電正接が0.67以下である樹脂を用いる。【選択図】図4
