Abstract: Empirically modulated antenna systems and related methods are disclosed herein. An empirically modulated antenna system includes an antenna and a controller programmed to control the antenna. The antenna includes a plurality of discrete scattering elements arranged in a one- or two-dimensional arrangement. A method includes modulating operational states of at least a portion of a plurality of discrete scattering elements of the antenna in a plurality of different modulation patterns. The plurality of different modulation patterns includes different permutations of the discrete scattering elements operating in different operational states. The method also includes evaluating a performance parameter of the antenna responsive to the plurality of different empirical one- or two-dimensional modulation patterns. The method further includes operating the antenna in one of the plurality of different one- or two-dimensional empirical modulation patterns selected based, at least in part, on the performance parameter.

Abstract: Antenna systems and related methods are disclosed. An antenna system includes an antenna controller configured to operably couple to an array of electromagnetic (EM) scattering elements. The controller is configured to determine a performance parameter of the antenna system for a plurality of different combinations of different spatial holographic phases and effective mode indices having different modulation patterns corresponding thereto, and select one of the modulation patterns based on the performance parameter corresponding thereto. A method includes storing data indicating a modulation pattern determined based on a spatial holographic phase and an effective mode index for each of a plurality of different main beam angles from the antenna, and controlling the antenna to operate with a main beam pointed in each of the plurality of different main beam angles by controlling the antenna to operate in each modulation pattern corresponding to the plurality of main beam angles.

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.

Abstract: Holographic beamforming antennas may be utilized for adaptive routing within communications networks, such as wireless backhaul networks. Holographic beamforming antennas may be further utilized for discovering and/or addressing nodes in a communication network with steerable, high-directivity beams. Holographic beamforming antennas may be further utilized for extending the range of communications nodes and providing bandwidth assistance to adjacent nodes via dynamic adjacent cell assist. In some approaches, MIMO is used in concert with holographic beamforming for additional channel capacity.

Abstract: Inter-element couplings between radiative elements of an antenna can be reduced by increasing resonant frequencies for first selected radiative elements and decreasing resonant frequencies for second selected radiative elements. In some approaches, the radiative elements are coupled to a waveguide and the antenna configuration is a hologram that relates a reference wave of the waveguide to a radiated wave of the antenna. In some approaches, the antenna configuration is modified by identifying stationary points of the hologram and then staggering resonant frequencies for radiative elements within neighborhoods of the stationary points.
