In one embodiment, an integrated circuit antenna array is provided that
includes: a substrate, a plurality of antennas adjacent the substrate;
and an RF feed network adjacent the substrate for transmitting RF signals
to the plurality of antennas and for receiving RF signals from the
plurality of antennas, the RF feed network coupling to a distributed
plurality of phase shifters integrated with the substrate for
phase-shifting the RF signals propagated through the RF feed network.
