Abstract
Some embodiments include packages and methods of making the packages. One of the packages includes a ground layer (e.g., a ground plane) of metal formed over a chip of die, an antenna element of metal formed over the ground layer, and a dielectric lens formed over the antenna element. The dielectric lens includes a plurality of dielectric layers that have graded dielectric constants in a decreasing order along a direction from the antenna element toward a top surface of the package.
