Abstract
An antenna device having a first material base and a second material base is provided. The first material base is three-dimensionally formed by first dielectric material. The first material base forms an opening inside, and has an antenna element arranged on a surface of the first material base. The second material base is formed by second dielectric material of relative permittivity higher than relative permittivity of the first dielectric material. The second material base is arranged in the opening of the first material base.
