Patent ID: 7236070

Claim:
An electronic component module comprising: a device-side module comprising: a first dielectric substrate that is formed with a first transmission line; and a plurality of high-frequency devices mounted on a first surface of the first dielectric substrate, at lease one of the plurality of high-frequency devices being connected to the first transmission line; a shielding means which surrounds and electromagnetically shields the plurality of high-frequency devices individually; and an antenna-side module comprising: a second dielectric substrate that is laid on a second surface of the first dielectric substrate in such a manner that they are arranged in a lamination direction and that is formed with a second transmission line that is electrically connected to the first transmission line, the second surface being opposite to the first surface; and an antenna element that is provided on the second dielectric substrate and electrically connected to the high-frequency device via the second transmission line and the first transmission line.
