Phased arrays are already in phones that have mm wave antennas ;) usually only 1 dimension though. But it's not inconceivable they will add one capable to reach a satellite. Obviously the number of elements and thus the gain will be lower than the one Ina starlink station. But with slower speeds you don't need as strong a signal.
