Yea but increasing frequency helps with that. With directional antennas the satellite would need attitude control which would benefit greatly from miniaturization. For the most part, miniaturization would come from incorporating systems on chips. Most op amps and microcontrollers are much smaller than their packages so including those systems on a single die in a single package are capable of massive savings in space. This is what made smart phones even possible .
