1. A method of spatial control of a phased array system having a plurality of antenna elements, the method comprising:

  • providing a baseband signal;

    baseband phase shifting the baseband signal to provide a plurality of baseband shifted signals for controlling phase of each of the plurality of antenna elements;

    upconverting each of the baseband shifted signals to a radio frequency signal;

    applying each of the radio frequency signals to the plurality of antenna elements to thereby provide for the spatial control of the phased array system.
