1. A polarized twist, space-fed, electronically scanned, planar phased array antenna comprising:

  • a substrate;

    a plurality of space-fed, electronically scanned phased array radiating elements disposed on said substrate for receiving and transmitting radio frequency signals, each said phased array radiating element comprising a plurality of ortho-linear polarization phased array elements and a plurality of phase shifting elements, each one of said phase shifting elements being independently associated with one of said ortho-linear polarization phased array elements; and

    a control circuit for controlling said phase shifting elements to produce a desired phase shift in said radio frequency signals transmitted by said antenna to thereby enable steering of a radio frequency signal transmitted by said ortho-linear polarization phased array elements.
