Abstract

A composite antenna device is provided that is capable of achieving gain enhancement of a patch antenna and further miniaturization of the entire device size. A composite antenna device capable of receiving signals of a plurality of frequency bands for a vehicle includes a base plate, a first antenna, and a second antenna. The first antenna is constituted by a patch antenna placed on the base plate and capable of receiving signals of a first frequency band. The second antenna is constituted by a capacitive antenna capable of receiving signals of a second frequency band lower than the first frequency band. The second antenna includes a top load portion disposed so as to cover the first antenna and has at least one conductive planar body functioning also as a wave director for the first antenna.
