| 1. An antenna system, comprising:
a reconfigurable multiple sub-array antenna system including multiple antenna sub-arrays each capable of being electronically
scanned for radio frequency communications, wherein each antenna sub-array includes a plurality of elements each capable of
radiating and receiving electromagnetic energy; and
an electronically reconfigurable power management and control system to selectively power each of the plurality of elements
to generate a desired beam pattern, wherein the power management and control system comprises:
at least two converters each capable of being selectively coupled to each antenna sub-array; and
a number of power sequencers corresponding to a number of antenna sub-arrays, each power sequencer being adapted to control
a voltage supplied by any one of the converters to at least one of the antenna sub-arrays when coupled to the at least one
of the antenna sub-arrays to supply power thereto.
