1. An antenna system, comprising:

  • an antenna controller configured to operably couple to control inputs of an antenna including an array of electromagnetic (EM) scattering elements having sub-wavelength spacing and carried by a body configured to propagate an EM reference wave, the antenna controller configured to;

    control the array of EM scattering elements, through the control inputs, to operate according to a holographic modulation pattern; and

    control the array of EM scattering elements to modulate a spatial holographic phase of the antenna itself over time to, on average, cause side lobes of an antenna gain of the antenna to be reduced.
