Patent attributes
A circuit element mounting portion provided on a dielectric substrate is configured so as to mount a high-frequency integrated circuit element, and includes a ground land and a plurality of high-frequency signal lands. The dielectric substrate is provided with an antenna element including at least one radiation element. The dielectric substrate is provided with an exposed terminal portion including an exposed ground land and an exposed high-frequency signal land. The dielectric substrate is provided with a first transmission line connecting one high-frequency signal land of the circuit element mounting portion and the radiation element. Furthermore, a second transmission line connecting another high-frequency signal land of the circuit element mounting portion and the high-frequency signal land of the exposed terminal portion, and a ground conductor connecting the ground land of the circuit element mounting portion and the ground land of the exposed terminal portion are provided.
