1. An antenna unit, comprising:
an integrated circuit package containing an adaptive array of multiple slot antennas embedded in the integrated circuit package, wherein each slot antenna of the multiple slot antennas includes a planar slot antenna element at an upper surface of the integrated circuit package and a cavity embedded in the integrated circuit package below the planar slot antenna element, and wherein the multiple slot antennas of the adaptive array are embedded in the integrated circuit package directly next to each other without intervening circuitry; and
an artificial dielectric layer separated from the integrated circuit package by a layer having a dielectric constant close to one, wherein the artificial dielectric layer is placed at a predefined distance above the upper surface of the integrated circuit package, wherein the artificial dielectric layer includes a superstrate and a first grid of metal patches disposed on a first surface of the superstrate, and wherein the first grid of metal patches extends continuously over all of the multiple slot antennas in a regular pattern.
