ABSTRACT:
A wireless communication device includes: a high frequency circuit for generating a high frequency signal, the high frequency circuit being provided on a high-frequency-circuit surface of an integrated antenna module substrate mounted on a mounting substrate; a patch antenna for irradiating radio waves indicative of the generated high frequency signal, the patch antenna being provided on an antenna surface of the integrated antenna module substrate; and a ring-shaped grounding surface provided on the antenna surface of the integrated antenna module substrate so as to surround the patch antenna. This allows reducing surface waves irradiated from the end of the integrated antenna module substrate and improving antenna characteristics.
