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.

Abstract
Antenna systems and related methods are disclosed. An antenna system includes an antenna controller configured to operably couple to control inputs of an antenna including an array of electromagnetic (EM) scattering elements. A method includes controlling an array of EM scattering elements to operate according to holographic modulation patterns, and modulating at least one effective EM property of the antenna over space, time, or a combination thereof to, in the average and/or the aggregate, cause side lobes of an antenna gain of the antenna to be reduced.
