Electronic component module

摘要

An electronic component module includes a mounting substrate including a shield layer and on which a first cavity and a second cavity are formed. A first electronic component positioned in the first cavity is used in a first frequency band. A second electronic component positioned in the second cavity is used in a second frequency band. Lid members seal the first cavity and the second cavity. Patch antennas transmit/receive radio waves in the first and second frequency bands, the antennas being formed on a surface opposite to the electronic components mounting surface. And, connection terminals formed on the mounting substrate are electrically connected to the electronic components through transmission lines.
