1. A communication system comprising:
a first radio frequency (RF) module circuit;
first radio frequency front-end (RFFE) circuitry coupled to the first RF module circuit;
a second RF module circuit;
second RFFE circuitry coupled to the second RF module circuit;
a phased array antenna coupled to the first RFFE circuitry, the phased array antenna comprising:
a ground plane;
a plurality of antenna elements located in a first plane that is separated from the ground plane by a first distance;
