Abstract: 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.

Abstract: 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.
