Abstract:
A microstrip patch antenna including:a substrate having spaced-apart first and second surfaces, said substrate having a thickness substantially smaller than a wavelength at a frequency to be coupled to said antenna;a conductive pattern defining a fractal of iteration order N disposed on the first surface, wherein said fractal is defined as a superposition over at least N=1 interations of a motiff, an iteration being placement of said motif upon a base figure through at least one positioning selected from a group consisting of (i) rotation, (ii) stretching, and (iii) translation;wherein said motif is selected from a group consisting of (i) Koch, (ii) Minkowski, (iii) Cantor, (iv) torn square, (v) Mandelbrot, (vi) Caley tree, (vii) monkey's swing, (viii) Sierpinski gasket, and (ix) Julia; anda conductive pattern disposed on the second surface.
