ABSTRACT:
A dielectric carrier is disposed on a substrate and formed with a recess. A first antenna element is provided on at least one face of the carrier and electrically connected to the substrate. A second antenna element is provided as a ceramic antenna and disposed in the recess. A first dielectric layer is provided between the first antenna element and the second antenna element. A second dielectric layer is provided between the substrate and the second antenna element. The recess is formed at a position which is sufficiently away from a power supply point to the first antenna element and a point at which a potential of the first antenna element has a maximum value.
