Abstract
An antenna apparatus capable of improving antenna characteristics as well as miniaturizing a size is provided. An antenna apparatus includes a base, an antenna conductor, and a terminal as an external connection terminal. The base is made of a dielectric composite material containing resin and ceramic powder. The antenna conductor is arranged on a surface of the base. The terminal is electrically connected to the antenna conductor. A relative permittivity (∈r) and a dielectric tangent (tan δ) of the dielectric composite material satisfy a relation of: tan δ≦0.0024×e(0.0341×∈r).
