Abstract
Antenna and related structures and circuits are described having a ground plane or ground counterpoise system that has at least one element whose shape, at least is part, is substantially a deterministic fractal of iteration order N≧1. Using fractal geometry, the antenna ground counterpoise has a self-similar structure resulting from the repetition of a design or motif (or “generator”) that is replicated using rotation, and/or translation, and/or scaling. The fractal element will have x-axis, y-axis coordinates for a next iteration N+1 defined by xn+1=f(XN′ ybN) and yN+1=g(XN′ yN′ where XN′ yN define coordinates for a preceding iteration, and where f(x,y) and g(x,y) are functions defining the fractal motif and behavior, in another aspect, a vertical antenna is top-loaded with a so-called top-hat assembly that includes at least one fractal element.
