Surface-to-Surface Transition via Electromagnetic Coupling of Coplanar Waveguides

A transition is investigated which couples waveguide on one substrate (a motherboard) to coplanar waveguide on another substrate surface (a semiconductor chip or subarray) placed above the first. No wire bonds are necessary. A full-wave analysis using coupled line theory is presented and verified experimentally. The use of this transition for coupling to millimeter-wave intergrated circuits is discussed.
