1. A system for wideband antenna performance over a 3 dB bandwidth from 600 MHz to 1500 MHz, the system comprising:

  • a plurality of nested sleeves, wherein each sleeve includes one or more layers of dielectric substrate having a conductive array of resonators, wherein for at least a portion of the conductive array, the resonators are separated by a non-zero distance corresponding to less than ⅕

    λ

    when the system is operating at a lowest operational frequency, wherein each of the plurality of nested sleeves is separated from the others by a non-zero radial distance, and wherein at least a portion of the one or more sleeves includes a conductive array having resonators that include self-similar geometry.
