1. An electronically scanned antenna system comprising:

  • a plurality of array elements each comprising a plurality of reflecting components capable of reflecting an electromagnetic wave incident thereon, wherein each reflecting component is interconnected to at least one reflecting segment by at least one switch, wherein when the at least one switch is in a closed state a respective reflecting segment is electrically coupled to the respective reflecting component to thereby alter a reflective geometry of the respective reflecting component; and

    a control system capable of controlling the at least one switch to thereby control said plurality of array elements to provide a desired degree of phase shift to a signal reflected from the antenna, wherein said control system is capable of controlling the at least one switch of one reflecting component at the same time said control system controls corresponding switches of other reflecting components.
