Patent ID: 7227502

Claim:
A patch-antenna integrated module comprising: a patch antenna including a dielectric substrate to which at least one first through hole is provided, a first ground electrode at least partially covering a back surface of the dielectric substrate, an antenna electrode partially covering an area of a front surface of the dielectric substrate, the area positionally corresponding to the first ground electrode, a second ground electrode provided within the area in a vicinity of the antenna electrode, the second ground electrode having the through hole underneath, and a conductive material provided in the first through hole so as to electrically connect the first ground electrode and the second ground electrode; and a substrate being provided with a second through hole and stacked to the back surface of the dielectric substrate of the patch antenna, a semiconductor chip for inputting/outputting power to the patch antenna being mounted to the substrate, wherein the semiconductor chip, the antenna electrode, and at least one of the first ground electrode and the second ground electrode are connected by means of a conductive material provided in thesecond through hole provided for the substrate.
