  • Patent number: 10361481
    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.
