Patent ID: 8912858

Claim:
A device comprising: a low loss substrate comprising, on a first side, a contact location for a mm-wave integrated circuit, and on a second side, a waveguide location; a planar transmission line extending along said first side from said contact location to above said waveguide location as a monopole waveguide feed; wherein the planar transmission line including said monopole waveguide feed extends along a single planar conducting layer; connection bumps configured to connect said mm-wave integrated circuit to said low loss substrate at said contact location; a soft laminate comprising a second cavity located below the waveguide location; the second cavity configured to receive a wave transmission from the waveguide feed and forward said wave transmission to a waveguide located below the second cavity; and a back-short located essentially above the waveguide location; the back-short comprises a first cavity of depth equivalent to about a quarter wave-length, and is configured to reflect energy into said waveguide.
