Abstract:
A millimeter wave module comprising:1) a first substrate having a face, said first substrate further having:a) a first cavity with bottom and side faces;b) a conductor on said bottom and side faces of said first cavity;c) a connection part on said face of said first substrate and around said first cavity, said connection part being electrically connected with said conductor;d) an air layer in said first cavity;2) a second substrate having a face, said second substrate being a dielectric substrate and having:e) a microstrip filter having metal patterning on said face of said second substrate; andf) a connection part connected to said metal patterning;said second substrate mounted to said first substrate by connecting the connection part of said first substrate with said connection part connected to said metal patterning, with said metal patterning facing said air layer in said first cavity and covering said first cavity; and3) a millimeter wave component having a face, said millimeter wave component having a connection part on said face thereof, and a second cavity in said first substrate with an air layer therein, wherein said millimeter wave component is mounted on said first substrate by connecting said connection part of said millimeter wave component with said connection part of said first substrate, with said millimeter wave component facing said air layer in said second cavity on said first substrate and covering said second cavity.
