Abstract:
A millimeter wave module comprising:1) a first substrate having a face, said first substrate further having; a) a first cavity; b) a conductor on said face of said substrate; 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; and d) an air layer in said first cavity; and 2) a second substrate having a face, said second substrate being a dielectric substrate and having: e) a microstrip having metal patterning on said face of said second substrate; and f) a connection part directly electrically connected to said metal patterning, said connection part provided on said face of said second substrate; said second substrate mounted to said first substrate by connecting the connection part of said first substrate with said connection part directly electrically connected to said metal patterning, with said metal patterning facing said air layer in said first cavity and covering said first cavity.
