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： A vehicle antenna arranged on a window glass for vehicle includes an element portion having a shape of a crank and being formed by a first element, a second element and a third element; and a feeding portion configured to feed power to the element portion. The first element has a first upper end portion and a first lower end portion, and extends in an up-down direction of the window glass. The second element has a second upper end portion and a second lower end portion, and extends in the up-down direction of the window glass. The third element extends between the first lower end portion and the second upper end portion. A first distance between the first lower end portion and the window glass is different from a second distance between the second upper end portion and the window glass.
