Abstract
A patch antenna system comprising: an integrated circuit die having an active side including an active layer, and a backside; a dielectric layer formed on the backside; and a redistribution layer formed on the dielectric layer wherein the redistribution layer forms an array of patches. The patch antenna further comprises a plurality of through-silicon vias (TSV), wherein the TSVs electrically connect the array of patches to the active layer.
