1. An antenna system, comprising:
an array of antennas, each antenna to emit electromagnetic waves, wherein each antenna is presented with a load that is different from other antennas in the array; and
a control system, comprising:
a single transmitter to sequentially drive antenna sets;
a switching device to select, for each activation period in an activation sequence, an antenna set to be driven; and
a controller to:
determine an actual power output of each antenna;
determine a difference between the actual power output for each antenna and an average power output of all antenna sets; and
generate an adjusted control signal for the single transmitter based on the difference between the actual power output for each antenna and an average power output of all antenna sets such that the power output of each antenna is controlled to match a target power for that antenna, regardless of a load for the antenna.
