The invention provides a vehicle antenna device capable of ensuring desired antenna characteristics of a satellite antenna and a communication antenna. An antenna device for a vehicle is provided with: a dielectric plate mounted on the vehicle; a conductor plate adjacent to the dielectric plate; a satellite antenna provided below the conductor plate and receiving radio waves transmitted from a satellite via the dielectric plate; and a communication antenna provided below the satellite antenna and transmitting and receiving radio waves in the horizontal direction via the dielectric plate to and from the outside of the vehicle. The satellite antenna is provided with a radiation conductor that does not overlap the conductor plate, and a ground conductor that is positioned between the radiation conductor and the communication antenna, when viewed from the vertical direction.
本发明提供一种能够确保卫星天线和通信天线各自所期望的天线特性的车辆用天线装置。一种车辆用天线装置,其具备:安装在车辆上的电介质板,与所述电介质板邻近的导体板、设置于比所述导体板更靠下方且接收从卫星经由所述电介质板传来的电波的卫星天线、以及设置于比所述卫星天线更靠下方且与车外之间经由所述电介质板在水平方向上收发电波的通信天线,所述卫星天线在从铅垂方向看的视角下具备与所述导体板不重叠的辐射导体、和位于所述辐射导体与所述通信天线之间的接地导体。
