摘要： An antenna and an antenna apparatus for vehicle that can achieve reduction in size are provided. The antenna includes a dielectric body, a radiation conductor disposed on a first principal surface side of the dielectric body, and a ground conductor disposed on a second principal surface side of the dielectric body. The ground conductor is a planar conductor disposed within a rectangular region having a length LG1 in a first direction and a length LG2 in a second direction. When the ground conductor is divided into a first region and a second region, the ground conductor includes a slit that starts extending toward the inside of the ground conductor starting from an outer edge of the ground conductor in the first region.

摘要： Provided is a vehicle antenna system that is able to efficiently receive circularly polarized signals from the zenith direction. A vehicle antenna system (100) is provided with window glass (30) for a vehicle (20) and an antenna element (40) that is able to receive signals of a predetermined frequency band. The antenna element (40) is provided on a first principal plane of a dielectric substrate (43), and includes a radiating conductor (41) that is able to receive circularly polarized signals of a first frequency, and a grounding conductor (44) positioned opposite the radiating conductor (41) via the dielectric substrate (43). The normal direction of the first principal plane is less than or equal to 45° relative to the vertical direction, and the radiating conductor (41) is positioned away from the inner surface of the window glass (30) via the dielectric layer (60) in the direction of the vehicle interior.

摘要： An antenna includes a radiation plate 56 equipped with a radiation surface that radiates radio waves and a feed point that is a location supplied with power from a transmission line. When looking at the radiation plate along a horizontal direction, the feed point is provided at a position separated from a centroid of the radiation plate by a distance A. When looking along a thickness direction of the radiation plate, locations between an end portion of the transmission line connected to the feed point and an intersection portion intersecting with a peripheral edge portion of the conductor plate, overlap in the thickness direction of the radiation plate with a specified area between a third straight line and a fourth straight line.
