Would we see a day where wireless devices have software-defined antennas?

The idea is to modulate the directionality of the transmitter/receiver antenna with no bulky or moving parts.

These steered arrays have been standard radar technology for decades. The signal processing involved is not that advanced. I assume when it's needed it can be done.
