Claim Text:
1. A package structure, comprising: an RFIC (radio frequency integrated circuit) chip; an antenna package comprising a glass substrate, at least one planar antenna element formed on a first surface of the glass substrate, a ground plane formed on a second surface of the glass substrate, opposite the first surface, and an antenna feed line formed through the glass substrate and connected to the at least one planar antenna element; and an electrical interface between the antenna package and the RFIC chip, wherein the electrical interface comprises micro via joints, wherein the micro via joints are formed within a BEOL (back end of line) structure of the RFIC chip, and wherein the micro via joints provide electrical connections between wiring of the BEOL structure and metallization on the second surface of the glass substrate, wherein a backside surface of the RFIC chip is directly bonded to the ground plane on the second surface of the glass substrate of the antenna package using a layer of adhesive material.
