Abstract:
1. An apparatus comprising: an antenna undefined by an opening angle and having a first element whose physical shape is defined substantially as a deterministic fractal of iteration N≧2 for at least a portion of said first element, wherein said deterministic fractal is defined as a superposition over at least N=2 iterations of a fractal generator motif, an iteration being placement of said fractal generator motif upon a base figure through at least one positioning selected from the group consisting of (i) rotation, (ii) stretching, and (iii) translation, wherein said antenna has a perimeter compression (PC) parameter defined by: where: wherein A and C are constant coefficients for a given said fractal generator motif, N is an iteration number, and D is a fractal dimension given by log(L)/log(r), where L and r are one-dimensional antenna element lengths before and after fractalization, respectively; and wherein iteration N=2, PC is approximately 1.9, termination impedance is substantially 50Ω, and gain is substantially at least within 1 dB of unity.
